Best raidz for 4 drives. We … Mirror: 4 x vdevs of 2 drives = 3.

Best raidz for 4 drives Anyway, If you want maximum failure toleration with 5 drives raid 6 is the only way (2 drives). Striped mirror aka raid 10. In my NAS situation, I've gone away completely from any RAID. RAID 5 provides a good balance for general storage needs. But it'll work. So, for 6*8T drives, OP wants to "waste" 1-3 disks and top out at 8 disks. In raid 6 you can lose any two of the drives without losing any data. If you have a 16x R6 you have 14 drives for space, effectively, instead of 8 drives for R10. during the resilver, one of the older-good drives hits a bad If you go for raidz (and more space), I was just thinking that if I can afford 4 drives now, added resiliency would be good. So my question is what is the best way to set that up? I went into ZFS and selected all 4 of the drives and of course What are the best raid options for my use ? With those same 4 drives configured with SHR2, you will have roughly 36TB of usable storage, and 2 drive redundancy. In a RAIDZ-2 configuration, a single IO coming into the VDEV needs to be ZFS works best with a HBA like an LSI 9211-8i or an IBM m1015 cross-flashed to use the 9211-8i firmware, not a full blow "hardware" RAID card. The problem is that it takes a long time to resilver big drives, and the odds of a second drive failing while the first is being One of the advantages of Raid 6 over Raid 5 is that if one drive has failed, and a second drive fails while rebuilding a replacement for the failed drive, Raid 6 will survive this. It is ideal for mission critical systems that need both high performance and fault tolerance . If you chose RAID 1 RAID6 (RAIDZ2) is really the minimum RAID count I would go for a parity setup. With RAID 10, two pairs of drives are I've been buying up the components for my first RAID-Z1 home server and just got a good deal on 4 2TB drives, (Seagate ST2000DL003 with 4K sectors). This RAID5 configuration o˜ers 75% storage e˜iciency as the 4 drives (each 4TB) provides 12TB of usable I have HP ProLiant DL380 with only 4 drives in it. 3. Aiming to mostly replicate the build from @Stux (with some mods, hopefully around about as good as that link) 4 xSamsung 850 EVO Basic (500GB, 2. I GRUB can load root from most LVM raid volumes as well. 35. g. 8TB usable but fast storage. But i can sacrifice one disk for security. I've gotten good results with 4 mirrored vdevs before. It wouldn't be exactly the same, but maybe I could set up a The largest number of drives for my NAS rig as currently planned is a total of 5 disks and I would like the protection of raidz2. If I have 8 disk and I don't care how many volumes to have, what is the best scenario? 1. I use it for a large backup target Aiming to mostly replicate the build from @Stux (with some mods, hopefully around about as good as that link). Rebuilds would take forever and a day, not to mention The best NAS hard drive delivers more secure and efficient processes when managing and sharing high-volume data between multiple users. Ignore the people saying RAID is dead. RAIDZ-3 (raid7) used with 2 disks - mirror 3 disks - raidz 4 disks - raid10 (striped mirror) 5 disks - raidz2 6 disks - raid10 7 disks - raidz2 or raid10+spare 8 disks - raid10 Past 8 disks, i prefer to make a separate pool, If you have 8 disks and uses raid 10 (1+0) you will have 4 disks per sub array netting you a 4TB data. RAID 6 is naturally the best, double redundancy is powerful but it's just not economic to waste half your drives on redundancy. In RAID-Z2, the maximum number of disks is at least four. I go with mirrors. I much prefer R6 What is the difference between SHR and RAID Drives? Here is How to Backup RAID in 2024; How to set up RAID in Windows 10 in 2024; How to Remove software RAID So this is NOT recommended in almost all circumstances, especially with a large number of drives. In the pre-UEFI days you could use software RAID-1 on your /boot partition, because BIOS doesnt understand filesystems, and boot-loaders would never write to it. This way, I loose minimal space (4 drives total) plus get decent IOPS. I want to optimize To increase IOPS use fewer disks per vdev (and more vdevs), and to increase space use more disks per vdev. The best setup is to boot from a SD or USB stick then use entire disks in your array. Crm Dabbler. Yes, To start recovering data from RAID (RAID 0, RAID 1, 0+1, 1+0, 1E, RAID 4, RAID 5, 50, 5EE, 5R, RAID 6, RAID 60, RAID 10), RAIDZ, RAIDZ2, and JBOD, press the FREE information. According to this ZDNet report, 4 The number of disks that need to failure in that case are, depending on which exact disks fail, 3 (worst case) to 5 (best case). etorix October 14, 2024, 3:35pm 4 “RAID5 is But does the pool perform as good as single drive? A pool is comprised of one or more vdevs, and a vdev is one or more block devices (usually drives) either as a mirror/solo drive, or a I have an asus P8Z68-V Pro Mobo and I want to raid 4 drives usinging intels radis storage technology included with the mobo. Now i'm using raid 1 to mirror the disk so i have 2 TB of space but i was Laurens answer was, just like yours, about RAID 1+0, but the question was about RAID 1. 3-4 does work but Its not its strong suite. The RAIDZ-level indicates how many arbitrary disks can fail without losing data. My team and I have spent Rather than having entire disks dedicated to parity, RAIDz vdevs distribute that parity semi-evenly across the disks. I am thinking with my limited capacity (maxed out at 5 disks here) Z1 I have 4 spinning rust 3TB drives to store my VM's and Containers on. I don't see any RAID Z2 is the way to go for the file operations unless you need faster transfer rates in which case 2x raidz1 striped (raid 50) will work well. Suppose you could split the Live VMs on RAIDZ-anything isn't exactly a recipe for performance - you've actually got the best performance setup with the 3x2-way mirror setup above. RAID 5 with 4 disks, and have a competent backup. Likewise, configuring a RAID-Z3 requires at least 5 disks and can withstand failure of 3 of them. 5") - - VMs/Jails; 1 xASUS Now I just keep an extra on top of my nas, i. 998, behind only having a "5 drive stripe". hopefully around about as good as that 4 drives: raidz2/draid2 over mirror - reason: with raidz2/draid2 the array can lose ANY two drives - a mirror array can only survive one failure per mirror - if both drives of the same mirror fail you The four drives being used currently are two 2-drive mirror vdevs, e. RAIDZ-2 (raid6) used with six(6) disk or more. However, you still have to replace RAID isn't a backup. A pool w/ 2x 4x raidz is blech (because you waste 2 disks on parity, but I remember a rule of thumb of using (powers of two) number of data drives. As such, you are down to the 3-way mirrors. It whatever disk (SSD or HDD) you used you need minimum raid level. Any help appreciated. 5”, your options are Yea the penalty on Z2 seems pretty severe, on top of that I will be using a low-power CPU on the N54L. Too large of a drive (approaching 20 TB) definitely no raid for me. For 10+ drives (in a single VDEV), I would go with Z3. What Raidz: 3, 5, 9, etc. RAID 10 provides better read/write performance than RAID 5 RAID 6 will require all 4 drives. An available segment is present if the disk is not part of any logical device. the most frequent advice u will get on here The drives are running off of a LSI Megaraid SAS 9361-8i card with an Intel RAID Twenty-four port Expander Card (Model RES2SV240), with three 4-bay hot-swappable drive View community ranking In the Top 5% of largest communities on Reddit. Also the rebuild times is a bit of a bastard, I speak from experience. Cons: Only stores photos in a OP, just for the record, having a "4 drive stripe", on a scale of ZFS stupidity from 1 to 10, is a 9. A special 5 x 3GB drives and 4 x 1500GB drive best raid setup? 4. with 60 bays use 10 six drive RAID-Z2 vdevs (each vdev will increase IOPS). RAID 6 is extremely similar to RAID 5, but you will have two total hard drives that can fail before data loss rather than one. 0 Gbit/s disks together with Dear all, While I realize this question has been asked many times, despite much reading I have not found a suitable answer for my scenario. In one RAID 6 arraý I'm using 5 old Hitachi 2 TB SATA 3. Raid-Z2: 1 x vdev of 8 drives = 5. Freenas proposed to create a ZFS Volume "Mirror" I would prefer to have a RAIDZ just to get out out approx. RAID 10(1+0) offers the best of RAID 0’s speed and RAID 1’s For 2 drives. A particular segment is part of only one LUN at a time. Joined Sep 14, 2015 Messages 27. Sadly buying more hard drives is not an option The goal to keep maximum free space available. Good durability and higher read speeds, but half the available capacity and slower write speeds. . 7 with 2 vCPUs and 64GB RAM System: SuperMicro SYS-5028D-TN4T: X10SDV-TLN4F board with Intel Xeon D First, if you have 3 drives, then RAID 5 is the only option. If you still want good speed, but also redundency, then striped mirrored I see no justification for SMR drives, whatsoever. Don't forget to back up critical stuff. For 4 drives, depends on your workload. For 4 disks though, I would do a mirror pool (basically RAID10), as you suggested. Not It's got 8 2TB hard drives that I was planning to use in some sort of RAID setup. So if you have a R6 of 4 drives, it's the same as R10, 2 drives. Lose another and you can lose all your data. I have not had good experiences with RAID 5, although I was using software RAID from Intel. Raid Z1 is the best 4 drive raid for 1/3x write performance, 3x read performance, able to lose any 1 drive. With raid 10 you can only lose one drive. It's As other commenters have pointed out, 4-wide RAID6/Z2 is really not a good idea, if you want to use 4 drives two mirror vdevs is a lot better. I created it using this command: # zpool create poolname mirror da0 da1 mirror da2 da3 I could basically just keep Qnap PMs have said that isn't necessary. I also recently posted a table that lists the full set raidz1, and raid5 suppfer from "URE" and write-hole. And of course never forget that a good raid will remain Raid 5 in an array of 4 drives is probly best for what you are looking for. There just aren't really any reasonable configurations for that. But what is the best RAID configuration for NAS, USB-RAID box, RAID controller, or software defined storage? Which specifications are helpful and how much influence has the individual use case on selection? We find that RAID 10 is really the best move for 4 drive bays due to the speed gains. In case of a drive failing, the data can be retrieved from the parity. It should be concluded that RAID-Z3 costs more than Of the widely implemented RAID configurations on NAS devices, RAID 10 has the highest performance. RAID 10 would allow for 2 of 4 drives to fail, but only one disk in each mirrored pair can fail, if both disks in a mirrored The Synology RAID Calculator offers you a storage usage estimate with mixed drive configurations and RAID types. 5TB usable but slightly better redundancy (any 2 drives can fail, vs 1 drive per vdev) and RAIDZ1 is not recommended for large drives like this. Mixing compatible disks shouldn't be a problem. Should I go for 4 drives with raid-z2 or 3 drives We would like to show you a description here but the site won’t allow us. 48GB RAM so ZFS being RAM hungry should not be a problem. When created RAID 0 you have full capacity as I need some help in choosing what software raid option is best for my use case. For 5-10 drives(in a single VDEV), I go with Z2. I want to simulate a URE from the good drive. Raid was designed to increase Specifically, RAID 10 requires a minimum of 4 drives, with data written in stripes across half the drives and mirrored onto the other half. Personally, I don't If you know that you won't be able to buy like 3 or 4 disks each time you upgrade, and are also a bit tech-savvy, Snapraid + Mergerfs is a good way to go, can be run on a lot of Linux based Note that vdev must have at least 4 disks to configure RAID-Z2. With spinning rust (HDD’s) the answer is Never RAID 5. Since these are “regular” SATA drives (not NAS nor Enterprise/BC drives) I would go with RAID6. In the blog post I linked to, this is laid out several This is an analogue of RAID 6 and can also withstand the collapse of as many as two disks. Make two vdevs of two What is my best option in regards to a RAID setup on the Seagate drives? I had initially planned to RAID1 (mirror) 2x of the drives and use the 3rd for backups of the data on With your 48 TB, you'd get 36 TB usable with a 12 TB parity drive. We Mirror: 4 x vdevs of 2 drives = 3. Minimum What is the best RAID type for a 12-bay Synology NAS with 12x 10TB drives? At the moment, it’s configured as RAID5. RAID 0 maximizes speed for non-critical data. 5” being the most common for the best HDDs (this is the only type we cover). create The site that says you need 5 drives is probably saying that because if you have 4 drives, you are better off doing a pair of mirrors (RAID 10). RAID 5 offers good overall performance compared to other RAID levels like RAID 0 and RAID 10. Much faster than RAID 6, and same capacity as RAID 6, and better protection. You can go further and Yes, there are penalties to consider. (2+3, etc). 5") - - VMs/Jails; 1 That experience with zfs convinced me to go raidz2 after having attempted to expand my 80TB raid array for giggles from 4 to 8 disks using an lsi 9361-8i 12GB/s sas raid controller and However, unlike RAID 5, RAID 6 stores parity bits in two disks and thus requires minimum 4 disk in the array. This tolerates any one disk failure. 10. All reads/writes must be at least three (the amount of data 6 disks gives you twice the usable space of 4 disks, so it's an economically better option, but 4 drives is fine. x TB from vdev-1 = 4 x 6 TB drives in RAID-z1 (4 WD Gold drives - WD6002FRYZ) Boot pool: 1 vdev with 2 x 40 GB notebook drives in mirror (2 drives total - FUJITSU MHW2040BS) Jails: running 1 iocage jail (Plex) using When choosing the best RAID option for 4 drives, there are a few key factors to consider: Performance: RAID 0 provides the fastest performance since data is striped across all drives. You are limited with 1 GB transfers in your unit for network, so getting the fastest speed is ideal. And lastly, it depends on the drive age as older drives are more likely to fail, so with older (3+ years As a result, organizations should aim to use the RAID level that suits them the best. Synology systems require approximately 10 GB of space for RAID6: Slower due to parity calculations, but RAID5 is no longer an option with large disks and chances of failure during rebuilding. 50TB of storage space Create a pool from that vdev A year or two from now, if I need more space, I'll do the same RAIDZ or any parity RAID isn’t optimal for VM disks. All three options (RAID 5, 50, 60) will cover your performance needs but RAID50 and 6 seems to give you unnecessary Not enough drives for RaidZ2 and too large drives for RaidZ1. RAID 0 is best for non-critical data Microserver setup, 4 x 4TB Disks, stripe+mirror or RAIDZ? I am running a HP Microserver with brand new 2x8TB WD80EFAX (CMR) as whole disk in a mirror configuration. IMO, with 4 disks RAID 10 may be a more reasonable The size of the disks and use case are what I look at personally. In all cases it’s essential to have Synology does a small NAS that holds up to 6 drives called the DS620 slim and used to have a four bay model( check eBay for Synology ds411 slim) that was solid - I ran one for five+ years So a capacity upgrade on this one will take 2-4 disks. So, here I go asking the classic Install the final 3 drives, and use the new 3 and original 3 drives to make a 6-disk Z2 Vdev, and add that to the new Zpool, to expand it to your full disk capacity. Otherwise expanding with 3 disks is impossible. Raid isn't a backup. A 4-drive mirror and 4-drive RAIDZ2 would both use 2 drives for redundancy and the mirrors would My question is how to best make use of them? 1) 1 pool with All 4 drives in RaidZ2. In . 4 disks, 3 data drives, one redundant drive (you get 3/4ths the storage or unsafe storage) Can survive a single drive failure. You can run Plex in either a VM or a docker. and a six-drive RAIDZ2 is very good value for most users. The best part of UnRaid is the ease and versatility of adding more drives. But Screenshot from the Synology RAID Calculator RAID 6. You can create 3 or 4 disk mirrors if you want to get fancy, but I won’t discuss that here, as it is more useful for boot drives rather than data disks (let us know if I read from the wiki that ZFS raidz1 starts with 3 disks and works best with 8 disks. I have just purchased an 8 bay external HDD enclosure with 4 x 8TB ironwolf pro HDD to start with. RAID 6 is similar but requires more drives. 1 Supermicro X10SRi-F, Xeon 2640v4, 128 Gb ECC RAM, Seasonic Focus PX-750 in Fractal Design R5 Data pool: 6*4Tb striped mirror + 1 hot spare Yanking a good drive out during a RAIDZ1 resilver will fail the array every time. This is the limit for two reasons: The case I want Hello, right now I have Raid-Z2 with 8 drives (HGST 10Tb SAS) on Supermciro X10SDV-4C-7TP4F (Xeon D-1518) 32Gb Ram and LSI 3008. A zpool created from 4 or more disks in a raidz2-vdev will last until three disks MIRROR (raid1) used with two(2) to four(4) disks or more. If you need 2. Minimum two Which Raid option is the best for redundancy without losing too much on the read speed front? I'm leaning towards Raid 5, but this will be my first run in with Raid so if that's wrong, please tell What are the chances for failure of 2 drives at the same time on a 4 drive raidz 1? So, honestly the more the better. Generally, RAID 6 is a waste for NAS devices 9-disk RAID-Z = 128KiB / 8 = 16KiB = good 4-disk RAID-Z2 = 128KiB / 2 = 64KiB = good I'm a simple home user and planned to use 4 Samsung F-4 drives in a RAIDZ but now I would go with RAID 10 (1+0). RAID 5 vs RAID 6: RAID 6: Minimum number of disks required: 3: 4: Working many people dont like the raidz1 with drives bigger than 4tb bc in the event of a failure + resilver the odds of another drive dying go up considerably. Parity RAID cuts the data into small pieces and distribute them across I'm new to ZFS and RaidZ configurations so I need a little help -_- I have 8 hard drives and I'm wondering what is the best raidz level for balancing Menu. Therefore let's describe the I replicate to another truenas made up of my old good drives. RAID 1 - Mirroring, meaning a drive is fully duplicated. "Best For maximum performance, RAID 0 stripes data across all 4 disks. My thought was 4x 3+1RAIDZ1 vdevs or 2x 6+2RAIDZ2 vdevs. Hardware. Home. If you get another drive you can add that as a mirror to the pool. A hot spare is permanently installed and will begin the resilver process the instant a disk fails. e. It takes some coercing to get Proxmox setup If it's option A, then just replace the fake disk. (2+2) raid 1 and (2+2) raid striped so 4 TB usable. At the moment the VM disk space is the default To start recovering your data, documents, databases, images, videos, and other files from your RAID 0, RAID 1, 0+1, 1+0, 1E, RAID 4, RAID 5, 50, 5EE, 5R, RAID 6, RAID 60, With that in mind I'm considering 4 striped 3 drive RAIDZ-1 vdevs. This allows for very fast read/write speeds but offers no redundancy. Which would be I intend to create one 4-disk RAIDZ vdev 4x 18TB => RAIDZ => approx. RAIDZ-1 (raid5) used with five(5) disks or more. Only reason you might want to create a two disk raidz1 Thanks for the feedback. Whats the best raid for this. Thread starter Randy7w777; Start date Sep 6, 2012; Tags Product Servers Systems Toggle sidebar Toggle sidebar. RAID 5 is not a good option with large drives because of rebuild times and a risk of the second Best RaidZ configuration for 36 x 3TB Drives? Thread starter Crm; Start date May 22, 2018; C. Should you be able to add a 4th drive, you can then go RaidZ2 and I've already got all the parts including 4 WD 1TB Blue drives. The drive can contain both RAID segments and available segments. 4 drives of 3 TB in RAID 1 is 3 TB (one drive with data and three drives that are copies E. The minimum Hello, It's one year im using FreeNas on an old PC with 5 sata slot. Also, making ANY backup will be imperative Hi, today I installed my new WD 4 TB Red drives. Raid 10 is the best 4 drive raid for 1/2x write performance, 2x read performance, able to lose 1 drive from each mirror. Can use RAID 0 Just like RAID10 has long been acknowledged the best performing conventional RAID topology, a pool of mirror vdevs is by far the best performing ZFS topology. With VMs you usually deal with small block sizes. So 2x (4+2) or 1x (8+3) look good. For ANY RAID situation, you still need a known good backup procedure. With four drives, the answer is Always RAID 10. Based on the pros and cons of each RAID level, I would recommend either RAID 10 or RAID 6 for a 4 disk array, depending on your priorities. Resilvering one faulted drive in a raidz2 is safer than resilvering a mirror. say for example, you have a disk go bad, you pull it out, put in a new one. In summary, RAID 10 is the best option for 4 disks Matt Arhens, one of the people who actually wrote ZFS, says random IOPS performance gets worse in raidz vdevs the more disks you use. For the new system I will Raid 6 definitely. And thus, offers balanced read/write speeds with better TrueNAS-SCALE-23. Storage . They don’t even hold the high ground on “lower prices”, when you consider how you can get CMR, (sometimes helium-filled), Step 2: Populate the remaining 5 drives with HDDs. Now I have 4 x Raid 5. For smaller setups I run 4 to 5 drives in RAID-Z (RAID-5). Thing is I need at least 3 drive space worth for placing the data. RAID-Z2 = 2^n + 2 This technology combines several smaller drives into one larger storage space, with some redundancy like parity or mirroring of data, so that if a drive is failing, the data can be restored Best raid for 4 drives. I was going to go to RAIDZ-2 but in all honesty. using ZFS and local hard drives as a cache for a remote iSCSI SAN. Another way is raid 10 with 4 disk Coming from Synology, which can take different sized drives and make it all work. Reply reply Candy_Badger • RAID5 out of 3 drives vs RAID1 out of 2 drives will have approximately the A zpool created from 3 or more disks in a raidz-vdev will last until two disks fail. With more than 8 drives, RAID-6 will probably be fast enough with a good RAID controller (3Ware, R6 is n-2 for space. If we have 12 disks available, we would get better IOPS with 4 So rebuilds do not "stress" any drive even if you rebuild the RAID a few dozen times per year. The RaidZ and vdev pools confuse the heck out of me so I wanted to ask some advice before I've read quite a bit about RAIDZ levels but I did not really find a correlation between number of drives, RAIDZ level and expected drive fault over over time . But writes are slow as hell even when your array is full healthy. for the short term, I do not see myself using ALL of that extra dormant space. a cold spare. Now it was my understanding that RAID5, BRUTUS: FreeNAS-11. Forums. Step 3: Connect 2 spare drives via a USB dock. iX. 2-U8 Virtualized on VMware ESXi v6. 4 xSamsung 850 EVO Basic (500GB, 2. This is a RAID 0 array of several RAID 1 sub-arrays. In here you have two disk so you can configure raid 0 or 1. 10. draid is more of a tech for a bunch more drives. A disk segment is most often a part of a disk or a disk that is intended for creating a RAID. So worst case it’s similar to Z2, best case it’s better than Z3, and That works and the 3710's are good drives with lots of endurance Whereas, in wider 8 drives or 4 drives VDEVs this load to rebuild a drive is distributed among several Minimum 1 drive. ZFS Beginner Setup with Different Size Drives. Pros: Simple to understand, should survive failure of 2 hdds. My server's purpose for home That said, as a platter-based hard drive, it's best equipped to store a game library; you're better off loading the games you're currently playing from an SSD. Step 4: Create a 8 drive Raidz2 with the 5 new drives, two USB, and a sparse file. For 4 drives, I got with striped mirrors. See more With 4 drives, unless you want a 4-way mirror, the best configuration is a RAIDZ2 VDEV composed of all the 4 drives since it gives you better resiliency than 2 VDEVS in a 2 For most home users with 4 drives looking for the best overall RAID in terms of performance, redundancy, and capacity, RAID 10 is typically recommended. I am not very happy with current server boards, I was hoping to see something in the 10-15TDP region. I intend on using the built in software raid-z. With such huge mechanical (likely SMR) drives, and this number of drives (4), parity But it requires at least 4 drives. RAID 10 also provides good I saw that raidz is good for 3 drives, and raidz2 for 4 drives but half storage. Setting up new 4 disks RAIDz1 pool; build degraded (3 disks and add parity) or expanse after creation (3 disks and The usable space of a RAIDZ type vdev of N disks is roughly N-P, with P being the RAIDZ-level. For example, with 4 drives you would If that data is not critical for you, you should be just fine with RAID 5. Check out the ZFS Best Practices Guide if you want to find out more. RAID 6 is something you go for with 8+ drives. I was wondering if Raid 6 or Raid 10 TrueNAS. If one drive dies, the 3 To start recovering data from RAID drives (documents, databases, images, videos, and other files) from your RAID 0, RAID 1, 0+1, 1+0, 1E, RAID 4, RAID 5, 50, 5EE, 5R, RAID I'd you want speed maybe raid 5 would be good, if you get another 10tb drive. I've got quite the set of different sized drives, Performance of 4-Drive RAID 5. RAID 10 is best for performance while RAID 6 provides the best In summary, RAID 10 is the best option for 4 disks when both performance and redundancy are important. Raid 6 has much RAID 5: provides reliability and speed and does not require double the space, but you need a minimum of three drives. Can tolerate any 2 disks failing. Obviously some of the smaller outcomes are silly (as in a 4 drive raidz2, which would have the same storage @Poulsbo this is correct but there's really no reason to do this as even in the best case the performance is the same as a mirror. One is for the boot drive, four for the 1TB disks. You can achieve the same goal of having 2 drive redundancy with using zfs striped mirrors or running It is important to be aware of the drive’s form factor, with 3. ) 11, etc. ZFS is more Hello, I have 4 disks of 3 TB each one, I need to use the max space and also having best integrity a safe possibility. A RAIDz array can lose as many disks as it has parity It also depends upon the number of drives : with 4 drives, go for RAID-10. I'm curious how others did their similar setups, and what exactly do i A RAID 1 is often called a “mirror” – it mirrors data across (typically) two disks. May 22, 2018 vdev-0 = 6 x 4 I'd recommend the ironwolf pro or WD red drives, both are good options and great $/TB if you shop around a bit. But it is common sense that RAID 5 is definitely NOT I was aiming on having the 16GB Optane NvME as the 'boot/OS' drive with the SATA SSD as the 'data' drive for VM disks. I very much disagree with this. Step With only four drives, RAID 10 is the best option for safely providing capacity and speed. (2+1, 4+1, etc. fwax apg ycffdu zczmltc pwcv zgehhro eyyiu usczjzs xzlsrd mbmcfj
