Model HUH721212AL4200 sold by Amazon Renewed at a great $18.25/TB delivered. Note these are SAS drives, not SATA.

I don't have any experience buying from here but one particular thing gave me pause— the product description says 6 month warranty (yikes) but elsewhere on the page it says Amazon Renewed's warranty is 12 months.

Might be a good purchase for those of you who have more resilient setups and can throw a bit of caution to the wind.

    fyi these are SAS drives so you wanna plug it into a sata connection you need an adapter

    • tonyjzx on 15/10/2025 - 15:10

      it dont work that way

      you need a sas controller

      if you have a sas controller you can buy a cable that breaks it out to four sata ports ie, 4 x sata hdds

      sas is a superset of sata ie. its superior to sata

      sas is a server tech… i have yet to see any consumer motherboard with sas but sure, i'd love to see one

      sas = serial attached scsi, yeah its that old, probalby more than 20yrs at this point, i used to babysit this shit all day

          just get a LSI 2008 SAS controller board for like $50?

        • Nom on 15/10/2025 - 17:57

          @ColonialBoy there's no mention of SAS anywhere on that page - all I can see are SFP+ ports and PCIe headers.

          • qwijibo on 15/10/2025 - 18:28

            @Nom: It has two SFF-8654 (8i) connectors. If they actually support SAS, you can get a breakout cable to drive 8 SAS/SATA drives off each one - so 16 drives - using a cable like this.

            Otherwise you can adapt those same connectors to pci-e slots or m.2 slots, and plug in a regular HBA, I suppose.

          That's not SAS. Just because the connectors look like some SAS interconnects does not mean it supports the SAS protocol or signalling. In the CWWK case, it does not.

          Similarly the (CWWK / Miniroute) N7 NAS board (which I have) also uses "SAS connectors" for SATA only. Good choice, as it reduces the HDD connector footprint on the motherboard.

          • ColonialBoy on 16/10/2025 - 05:55

            I should have posted this one with SFF-8643.

            • peteru on 16/10/2025 - 12:55

              @ColonialBoy: Still not SAS. Just a dense connector that gives you four SATA ports. I've got a CWWK / Miniroute NAS motherboard with two of those connectors. It's the Pro version of this one. None of them are SAS. I actually don't think CWWK have any SAS products. It's all either SATA or PCIe lanes on a dense connector.

            • Nom on 18/10/2025 - 20:53

              @ColonialBoy: @ColonialBoy the only way for any of these connectors to support SAS, is for them to be connected to a SAS controller chip on the Motherboard.

              None of these boards have a SAS controller onboard.

              That's why they're using these connectors for PCIe (connected to the PCIe bus) or SATA (connected to the SATA controller).

    For what it's worth I've had 8 of the 6TB model running 24/7 for 5.5 years with no failures, issues, etc. Great drives.

    A compatible SAS controller can be had on ebay for $20 but will use a PCI Express slot.

    • Ozzster on 15/10/2025 - 19:24

      There are USB ones or even NVME to SAS. But there is another problem. If your drive dies, or controller dies, you cannot just read the data by finding something else. You will need exact same controller to work with that data on the drive, even if it was RAID mirror. I had Adaptec one refusing to work in mirror and to work with another controller when a drive died.

      • CLGNet on 16/10/2025 - 09:20
        +1

        You don't have to have the same controller, your Adaptec likely isn't operating in IT mode and hence the incompatibility.

        Like another poster mentioned, HW RAID is a recipe for disaster.

    • tonyjzx on 15/10/2025 - 15:35

      this is pretty much it

      like sas never really took off outside of server grade shit because it wasnt that great over sata

      EXCEPT that you can have two sas ports run 8 sata drives off it and save motherboard space

      i'm pretty sure i've got a box of random 10,000-15,000 rpm sas drives in the garage - they sound like dentists drills

      • CLGNet on 16/10/2025 - 09:26

        Not sure, it's probably still the gold standard in the enterprise space? My IOM6 disk shelves over sff-8436 still does 400MB/s sustained for bulk file transfers, can finish few TB transfer in a matter of few hours, my SATA drive arrays would take at least 3 times as longer and most likely crap out in the midst of a rsync of such migrations. (Had to do 20 TB migration not long ago)

            Yes - I'm saying storage is CHEAP. Might not be as cheap but way easier to use NVME than server grade technology from the 90s

            You guys want cheap spinning disks? Fine - the rest of us are living in the modern era of chip storage - which again is very cheap and fast compared to what it use to be.

            If you want storage volume - there's a affordable tape drive you can buy right here with 15TB to make you feel good

              @eddyah: Your link points to tape cartridges that are $120. If you are going to go LTO-7 (which is preposterous as a substitute for online storage), you need to factor in the cost of the drive. That'll run you $5,600 ~ $12,000, depending on which one you pick. Oh, and those drives are SAS - the same SAS you are bagging as "server grade technology from the 90s".

              As far as NVME SSDs go, can you please tell me how much it would cost to replace 156 TiB (172 TB) of HDD storage with NVME SSDs? How exactly would you connect all those NVME SSDs to one file server?

      They could be cold spares which someone found at the bottom of the rack :)

      There are 4TB drives for around $75, and they are great value with Amazon's 1 year warranty.
      https://amzn.asia/d/7GBjrht

      I recently bought used 800GB Enterprise SSDs off eBay. The endurance rating on those drives is 14,600 TBW, while consumer discs are rated for 600TBW.

      When I tested the discs, they had 99% of their endurance remaining. One disc had a few errors and the seller immediately sent a replacement.

      Buying used Enterprise stuff is not for the faint hearted, but well worth the risk if you know what to look for.

      • wisc on 15/10/2025 - 21:36

        What did you use to test them? I also bought a drive for proxmax, zfs arc and l2arc.

        I got it for the plp, and figured if its just for proxmox it should be easy enough to rebuild if it fails

    • Whiplash on 15/10/2025 - 17:10

      Data centre drives are made or binned to a higher grade than consumer drives. Running 24/7 is thought to be more forgiving than constand on/off on motors, plus the ones that fail early have already been trashed.

      So these survivors are usually pretty good for civilian use for a few years.

      Think a thoroughbred horse now put out to stud for its retirement.

      Just buy one spare unit extra when one goes down so you can rebuild… Then be prepared to rebuild the whole lot as that failure is the canary in the coal mine

      • fullerms on 15/10/2025 - 17:22

        And remember kids

        RAID ≠ Backup
        RAID5 is worse than RAID0 (mirroring). You get the same single disc redundancy in both, but you could lose a second disc when rebuilding a RAID5 array.
        RAID5 < RAID6

          And the extra strain on the remaining 4 disk's rebuilding after a failure is sometimes enough to cause a second fail.
          Do not ask how I know about this from seeing it happen in production.

        • metalslaw on 15/10/2025 - 19:18

          Coming at this from a home user perspective,

          Given the size of the drives these days, I think it's crazy to build a raid 5 (or more) array, unless you really need the speed, for a 10GbE network, and you have enough money to actually have 2 offline backups of the files (with 1 of these sets offsite).

          The reason I think it's crazy, is because Raid is not a backup method. And a rebuild can not be relied upon 100%. Rebuilding even a 5 drive raid 5 12-24TB drive array will push the drives to 100% for at least a few days or more, and that's just asking for another failure, which ofc, if you don't have actual backups, could lead to total data loss.

          For a 2.5GbE home network, you only really need a single 2 drive raid 1 array to nearly saturate a 2.5GbE connection. And really, you are better off having actual offline (and offsite) backups, instead of also running this with or without 2 additional drives in a mirror (and still needing actual backups).

          The best option for most home users will always be JBOD'ing drives for data storage needs (with 2 full offline backups, of which 1 of these is offsite), and if need be, running a 2 drive raid 1 array, for doing work on across a 2.5GbE network.

          A 2 drive raid 1 array also suits being run as a steam library drive… Because you don't care that much if the data is lost, as you can just re-download the games (albeit it would take forever again). But the speed improvement across a 2.5GbE network is worth it. And you can have your complete library downloaded, and be able to play any game in your library, without having to wait to download it… And if the game needs ssd speeds, you transfer it onto your gaming pc's ssd drive, and play from there.

          Back to original topic. And for anyone still on a 1GbE home network, there is absolutely no reason to not keep it as simple as possible, and just JBOD everything. Because even single disk by itself, is enough to saturate a 1GbE network connection. Do the suggested 2 drive (1 offsite) backup I've suggested, and you should be data secure enough to cope with most disasters.

            @metalslaw: I got several SATA drives for $1, some of which 10k raid series of smaller sizes. Perfect use is to stripe them in RAID 0 to combine size and speed, and they perfectly replace SSD on a PC without M2. It is not noisier than just average SATA 7200. Read speed like 300 Mb/s, write about 200+ Mb/s, can't say it is way slower than SSD in reality. I tried RAID 5, it was horrible.

            • metalslaw on 15/10/2025 - 19:52

              @Ozzster: As long as you have a backup, and the array is on your own machine, yes, you can go wild with raid 0 sata drives (as long as you have 2 backups), unlees you have 0 because you don't need to worry about losing the data e.g. steam library.

              Your use case is definitely a good one.

              Over a network, it's a different story ofc.

              One reason I brought up the steam library over network using raid 1 max for a 2.5GbE network, is that this is an effective use of raid for a home user over a fairly cheap network. You can share this library between multiple machines. e.g. In my case, my everyday pc, my sim rig, and my tv pc. I thus don't have to have multiple duplicates of games across each device. I just have 1 set, that is shared. And then if I need ssd loading speeds for a specific game e.g. for when a UE5 game does dynamic loading while playing (looking at you Black Myth Wukong), I move it to the local machine's ssd, and play from there.

              Anyway, just food for thought.

            @metalslaw: Hardware RAID is a bad idea and has been for the last decade. JBOD and modern file systems all the way. I'm partial to BTRFS, it works better for me than ZFS. Parity based RAID (RAID5/6 and friends), especially at the block level is also an old technology that's past it's prime.

            I find that for the last decade BTRFS worked really well for me. I have a filesystem with 8 drives - a mix of 20TB, 22TB and 24TB WD Red Pro NAS HDDs. It used to be 14 drives, but I replaced all the 4TB and 8TB drives. Data is RAID1 (2 copies), metadata is RAID1c4 (four copies) and BTRFS is smart enough to balance it all without wasted space. All drives are attached using a mix of LSI SAS HBA and onboard SATA ports. Best case scenario I can get about 1,200MB/s reads, but that kind of performance is rare. The system has 2 x 10GbE and there is another BTRFS filesystem with multiple SSDs that go at over 2GB/s, so I could saturate the network. That's rare though. Backups go to two other systems using a combination of rsync, Proxmox backup server and BTRFS send/receive. Each method has it's pros and cons.

            I'll have to play with CEPH soon, just waiting on Amazon to deliver a bunch of SSDs for my nodes. Ceph allows you to distribute your data over many hard drives, different computers or even across sites. The redundancy and failure domains are configurable. Ceph also has support for snapshots and deduplication. Combine all that with multiple copies of the data in different locations and your file system is your backup solution too. Marry that with HA clustering and you are looking pretty good. Definitely not a consumer level turnkey solution. ;-)

            • Ozzster on 16/10/2025 - 08:01

      Actually, I agree with the neg, but not for the same reason. They are extremely resilient drives and the batch of 3 I got from them all tested perfect, SMART, low level format..etc.

      My gripe would be, the batch I got about 3 months ago, the price was $179 per drive on eBay, that's not counting cashback which shaved another 12% off. 2 days after the eBay plus sale was over, they increased the price to $199. It never came down ever since.

      Heck! it is still $199 on eBay right now as it has been, for the past 3 months.

    Hey, I love SAS drives. These are Not the old scsi interfaces types, but much newer. Yes, you Do need a SAS controller, and Yes the connectors to the controllers do type vary. Theres some good videos on YouTube explaining them. So some guys say there isn't much to be gained by using SAS drives, but there is. For starters newer SAS Hdd drives have 12gb/s transfer speed ( all mechanical sata hdd are 6gb/s )
    These faster drives need a later series controller typically a 93xx series which handles 12mb/s. 92xx type controllers only handle 6 gb/s, no matter the drives. Be careful with contrller ads, always check the speed ans specs. Secondly, yes, these drives, when cheap are used, they have come typically from data centres but have been looked after temp and environment wise. But they aren't home grade construction like most sata drives , they are enterprise grade, built for long use - built with fully supported platters - bearings at both axis points and in most cases, superior electronics, the larger ones with vibration sensors etc.. And lastly they are much cheaper for huge capacies.
    As a side note, some controllers are flashed " hba" this means the controllers dont act like a raid controller, but just as any other hdd controller, one connection to each drive, and each drive operates on its own as an independent drive.
    I have 3 older business Xeon "game" machines and one Chinese motherboard homebuilt Xeon gaming machine. I have SAS drives in all of them, and have almost zero problems.
    The smaller capacity 3.5" 1 or 2 Tb SAS drives are close to giveaway prices from some vendors .
    Oh yes, it all sounds a bit technical, but I have learnt about it all, and use them, and I'm 75.

    You cannot ‘adapt’ your SATA ports to SAS.
    Consumer NAS’s will not accept SAS.

    To run these drives most users run used ex-enterprise SAS cards flashed with IT-mode firmware. These are called HBA’s. These drives are really only useful for people with roll-your-own type servers/NAS’s which can install these cards. As a result used SAS drives are worth less than SATA drives on the used market.

    I don’t think this is a good deal. I’d want to pay $5-10 per TB to consider used ex-server SAS drives.

      Can't comment on the deal but appreciate the info. At first I was quite interested for my current NAS but sounds like its not a good direction to go for me. So appreciate the info.

    If I could see SMART before purchase I could consider it as a deal. Otherwise, it may be a drive after 45k hours on duty with thousands of bads just waiting to rest in peace in landfill.

      The batch I got from them has 32k hours, better then the 60k hours 2nd hand 6tb drives I got from another place, and the 12tb drives are circa 2019 from memory

        For 32k hours I wouldn't pay this much. I played roulette with Toshiba Red around this uptime, and it died during first linear read test while before had just a few bads.

        • CLGNet on 19/10/2025 - 16:55

          totally fair, just sharing my experience and speculation about the hours the disks might have been running already. afterall, I'm not touching them either unless they went back down to $179 listed price on eBay like they used to have it at. (then pair with the minimum 10% ebay flash sales with the shopback, and it might be worth it).

    Buying a refurbished HDD is a terrible idea, even if it really was refurbished.

    I'd wouldn't use these for anything I even remotely care about even if they were free.

    • CLGNet on 16/10/2025 - 11:05

      Enterprise drives, especially direct data centre pulls or the over commissioned ex government hobby toys are totally great, these refurbished ones made 5 to 10 years ago are probably still way more stable than those "New NAS SATA" drives on the market.

      The truth is, the more people think they are worthless, the better for users like me to find hidden bargains, like I said, they were 179 before, the 10tb ones are 159, and metrocom jacked up the price to 199 after selling them cheap. (Most 12TB SAS preowned in oz with free shipping starts around 225 bucks and most actual listings are 250 bucks or above)

        If the organisations originally using these no longer trust them to the point they have replaced them (presumably due to age), is that really something you want to risk your data with? I'd hope you're atleast got a layer of redundancy.

          The data centre pulls and over commissioned government toys purchased by government and commissioned by its contractors are being put on 2nd hand market for a reason. Not because they "No longer trust the hardware" nor entirely because of "old age"

          It's more because they are no longer fit for purpose, and the main purpose for data centres are because the ever growing demand for more storage from all levels of consumers (think about YouTube, Netflix and the ever growing demand for 4k, 8k contents, compound with recently increased NBN speeds national wide). Government? well, we all know how they play the annual budget games, they have to spend in order to get, think all those government vehicles in the auction, a lot of them are pretty mint thx to our tax payers money.

          I will take one of these (assume they are same batch from what I've got from Metrocom before) over any NEW wd REDs or Seagate Ironwolves manufactured today.

          :-)

        I tell you what. Metrocom are laughing all the way to the bank!
        Most 7+ year-old enterprise drives are discarded when datacentre equipment is decommissioned. Companies usually pay IT recyclers to properly sanitize or destroy the data, but many take shortcuts… often just doing a simple format.

        I’ve sourced a few drives from Metrocom and found recoverable data using basic recovery software from SATA drives. While SAS drives are typically less risky since they’re used in RAID arrays, a lot of these HDDs seem to come from overseas distributors, sold cheaply and without proper data wiping.

        im currently working in datacentres and every equipment decommissioned are tracked, i cant even get my hands on these hdd as they are contracted through 3rd party of which we require NAID AAA certificates.

        anyway.. I wouldnt spend 200+ on an older HC520 7+yr old thrashed drives. HC550.. maybe.

    I've bought a couple over the past week to replace some failing 12TB shucked drives in my RAID-Z2, which are reporting SMART errors.

    I'm running them on an old Adaptec 7500 series RAID card (in JBOD mode), flashed with firmware to allow both SAS & SATA drives.

    Here is the SMART info from the Amazon drives:

      smartctl -x would be more revealing, especially since it should list temperature history, cumulative I/O stats and most importantly error logs.

  • gamerkonks on 28/10/2025 - 09:53

    Anyone know if it's okay to mix SAS and SATA in a R720 with a PERC H730P controller?
