Cheaper than current eastdigital refurb prices for equivalent disks.

Not quite as good as the previous metrocom deal, but you do get next day delivery, 12 month warranty and straightforward change of mind returns if you don't like the look of its hours/cycles.

I believe the Zip deal should apply but don't have an account to check at checkout.

          How loud is the click thump? I'm not hearing any thumping noise on mine. I am using a dock with UASP. Make sure your drive is snug in the dock. I stick old gift cards between the dock and HDD to reduce the vibration.

          • dunnoz on 24/03/2025 - 12:25

            @zealmax: Yeah my dual dock has gaps, so it could be moving slightly.

            Once I put it in my NAS, it isnt as loud and all scans shows the HDD are healthy.

    Thanks op. ZIPSMILE worked using zip as payment and $10 off.

  • Bearlion on 21/03/2025 - 12:30

    Eastbay out of stock for many disks, I got a great deal on new 12TB Exos $232 december last year

  • MelBorn on 21/03/2025 - 12:50

    so what's the age and onhours? i assume it's already 5 years and ~20k hours?

    good deal if they haven't wiped the SMART data, bad if they have something to hide

    • HiBeam on 21/03/2025 - 13:28

      1198 days 23hours, power on time 28,775. Health shows as excellent.

    • frugaljerk on 21/03/2025 - 22:11

      The few I got have power on hours of ~28800, and a very low number (single digits) of power cycles.

  • Rage Roze on 21/03/2025 - 13:54

    Anyone know how long the deal will last for? Might buy second one if the HDD I get is a good disk

    • Pest85 on 21/03/2025 - 20:50

      Its a part of the Big Smile Sale from Amazon.

      Amazon is running an incredible sale event – the Big Smile Sale – and you’ve got until midnight Sunday March 23 to shop the red-hot deals.

  • Mikael on 21/03/2025 - 13:55

    Not delivery until 3rd April WA. OH well. Read here if any dramas with them. Gonna put in unraid for media.

    • Mikael on 22/03/2025 - 12:09

      Order placed but haven't taken money out yet. Hopefully they don't just send locally and cancel WA. Says delivery 2 April now

  • zealmax on 21/03/2025 - 22:30

    Received mine with 28,900 hours. Doing a surface scan now and it sounds really good. No clicking, just a smooth low pitch humming 270 MB/s. I am using a dual HDD dock. Might grab another one.

  • DreadEmperor on 22/03/2025 - 10:31

    Did they bump up the price? Showing up as $319.00 per unit in cart.

    • snep on 22/03/2025 - 10:43

      It's a little odd - I had one in my cart already which is still showing $271 at checkout even after refreshing the page and clicking through again. But opening a new tab it adds to cart at $319.

      So seems it may have been bumped up, yeah. I'll expire it.

    ordered and recieved. 28991 hours, 37TB read, 30TB written, powered on 6 times. Double boxed with a heap of bubble wrap.

    • McMaferMur on 22/03/2025 - 13:36

      Wow 3 years always on. This must be mining activity, right?

      • GUYANDSON on 22/03/2025 - 13:52

        nah, might have been used for chia farming but not for plotting. The read/write is way too low for that. Stored data and just sat there in a machine for the most part.

        Wow 3 years always on. This must be mining activity, right?

        These are enterprise drives; they will typically be left on from the time they're plugged in as servers don't get switched off.

        • Mikael on 22/03/2025 - 14:09
          +1

          Agree. Most likely server drives. 99% they will be fine. My guess is max 1 faulty in the whole batch. Probably gonna be the one i ordered lol

    • zealmax on 22/03/2025 - 14:50

      Mine had 3 powered on with the same number of hours as yours. Ordered another one today. I am planning to use them as offline backup with snapraid parity.

    • neflardio on 23/03/2025 - 23:30

      How are you interpreting the read/write values?
      I'm using Hard Disk Sentinel, and it says reckons my 3 drives range from 38tb - 42tb write and 8-12tb read. The read value is really low so wondering if Hard Disk Sentinel is misinterpreting the vendor specific total read/write fields.

        i have a feeling smart data attributes 241 (F1), 242 (F2) are in LBA (1 sector / 512B). what are the raw values for these attributes?

            @neflardio: those numbers you listed previously appear to be correct

            91997667140*512/1024/1024/1024/1024 = 42.8 TiB

            28194280292*512/1024/1024/1024/1024 = 13.1 TiB

            • neflardio on 24/03/2025 - 13:19

              @c64: Thanks! Very interesting usage numbers if correct.
              For those interested, my drives also have approx 28k on hours and 5-6 power cycles.

              • Rage Roze on 26/03/2025 - 20:54

                @neflardio: That seems par for the course as mine

                I just ran surface test and I'm getting errors right at end of the test. Did I get a faulty drive from Metrocom?
                I havent heard any weird sounds besides my first time booting it up with subtle click sound
                The fastest tranfer speed I got over it from WD RED NAS to that drive is around 160MB/s

                  @Rage Roze: That could be a problem.
                  Do a reverse surface scan (i.e. scan backwards) to see if that area really has a problem.

                  I think that you did a surface Read test.
                  I would do a "Disk repair (read test with sector repair)" or "Reinitialize disk surface (DESTRUCTIVE - all data will be removed)"

                  • Rage Roze on 25/04/2025 - 00:22

                    @nige0090: Just following up on this. I finally got around pluging HDD directly to motherboard & it passed hard disk sentinel's Write test (DESTRUCTIVE). No errors on my end.
                    Looks like usb sata dock was failing on me when been read too long in one go

            • Mikael on 02/04/2025 - 16:18

              @c64: @c64
              Got mine today. on the 241 it says 0012901477A7 and 242 says 00038B01B4B6
              No idea why letters in the output.
              This is in Hard disk sentinel. With your calculations on write is only 0.6 Tb. that doesn't seem right. Or just a drive that hardly got used in their config.

              Found it. arghh. Should've looked under. 38.9 tb written and 7.4 read

              • c64 on 02/04/2025 - 16:35

                @Mikael: they are hexidecimal numbers

                0x0012901477A7 = 79726671783 decimal
                0x00038B01B4B6 = 15217046710 decimal

                • Mikael on 02/04/2025 - 16:42

                  @c64: Thanks. Not bad values then. 37tb written 7tb read.
                  Running a full test now. Gonna take a long time but rather test it now then failing in my unraid.

      • Aussie Tim on 27/03/2025 - 12:35

        You are lucky, four of my six drives arrived today and have 299TB written each and 75TB read.

        This is with circa 28800 hours each

        Given the drives are rated for a workload of 550TB/year I guess that's OK but its higher all round than I would have liked

  • skillet on 22/03/2025 - 21:56

    Well done guys pushing sustainability to the furthest. Thank you WD for not renaming this drive. Thank you HGST for making such a solid product, thank you who ever enterprise for not drilling a hole into HDD, thank you Metrocom for reselling these, thank you OP for posting this recycling deal, thank you for taking the risk buying used disk. These helium drives will last at least 7 years in a mid size business, in my work servers they transfer an average of 40TB per month each. I have witness at least 212 of these HC550s 14TBs SAS variant operating at 54C for almost 5 years with no performance degradation, it's a very reliable disk, we are actually looking forward for warranty claim but seems like its not happening. Actually even HC520 are also very tough. Most of the HGST Helium filled HDD are solid.

      They were probably going to turn them into swiss cheese then realised people would pay $300 each for drives with 30k hours

    • c64 on 24/03/2025 - 10:47

      why would you let them cook at 54C? the WD HC550s are rated at max 60C.

      seagate claims, for their drives, that over ~40C is going to increase the the AFR https://www.seagate.com/au/en/support/kb/hard-disk-drive-rel… .

      they also allow for 250 power cycles per year

      • skillet on 24/03/2025 - 18:57

        Hardware is cheap, power to cool down the servers isn't. Plus it reduces carbon footprint, that's what the management thinks so we reduced the cooling power.

        • Nom on 24/03/2025 - 19:26

          If the drives are rated to 60c then I wouldn't think twice about running them at 54c 🤷🏼‍♂️ It's in spec, so what's the problem ?

          • c64 on 24/03/2025 - 19:48

            @Nom: sure, it is not exceeding the maximum rating, but it will also probably be decreasing the lifetime of the drive

      • Nom on 24/03/2025 - 19:30

        122F is 50c - they're saying that temps over 50c will increase the rate of failure. Not 40c.

        • c64 on 24/03/2025 - 19:47

          "The product shall achieve an Annualized Failure Rate - AFR - of 0.73% (Mean Time Between Failures - MTBF - of 1.2 Million hrs) when operated in an environment that ensures the HDA case temperatures do not exceed 40°C"

          for a seagate exos drive, seagate say their AFR is based an HDA case temp of <= 30°C

        • Mikael on 30/03/2025 - 22:19

          Mine is on its way. Probably Wednesday. Good to upgrade drives in unraid. Swap this to a bigger parity drive to start with. Just got one.

  • Mikael on 31/03/2025 - 13:37

    Random question and probably shouldn't be here.
    I get mine tomorrow or Wednesday. Going to use it to replace my 6tb parity drive on unraid and use that later as data drive. Question. Do i just plug it in and assign it as parity. When built remove the second parity (6tb) and assign that to data drive? OR do I have to replace it first in same slot as current parity is and do it this way? Hope it makes sense.

  • Mikael on 03/04/2025 - 21:11

    Ran full check using HDD sentinel pro. All perfect.
    37tb written 7tb read. Pleasantly surprised. Currently building parity in unraid. Write speed around 220MB/s
