First failed testing, waiting on exchange to arrive. Update, 2 of 5 drives failed testing, others working fine.
Received the seagate ironwolf 10tb drive, box was fine, physically no issues. Started seatools to test it, passed the short test. Started the long test, a several minutes later walked past and noticed the drive activity led wasn't even flickering, turned the monitor on and found that it failed, "likely due to unreadable sectors".Luckily i ordered this to expand my nas storage and not to replace a failed drive so not time critical.I have requested a replacement via outletpc and will update this review after testing that one. This purchase was giving seagate hard drives another chance after several drives failed in the past (spread over years). If the second drive fails, i'll have to switch to wd red pro 8tb, only a $11 cheaper than the ironwolf, but 2 tb smaller in storage. The real test will be if the replacement drive passes testing and works in the array, i'll order a second 10tb ironwolf drive in a few weeks, hopefully that drive will pass testing as well. Update: changing stars to 4, as the drive seems quite nice. Seatools short passed, but the long test passed, but only took a few hours, not trusting that. Ran dban 3 passes, took a few days, passed that, and smart info looks fine. Just put it in the synology nas, right now rebuilding, looks like it will take around 16 hours.Interesting thing is that the nas shows a ironwolf testing button (says beta, and the drive passed), and has a ironwolf logo instead of the generic hard drive logo.Will be ordering 2 more in a while one so the array can expand to use the new space, and a third so i can have a tested spare ready to go.Considering it takes so long to test huge drives a spare is a good thing to have handy.5/9/17 after the first (replacement) drive tested good and incorporated into the array just fine, ordered another 10tb drive, it tested good and as well went into the array just fine. Ordered a third drive (fourth if you include the original that was exchanged). Took longer to test than i thought the others did by about a day maybe a day and a half. Ran seagate tools long smart test and when i went back a few hours later it had failed with a code, just got done doing the return process for the drive, and awaiting another.Two failed drives out of four, not great. The two in the array passed an additional test pass after they finished the array rebuild.I'll keep an eye on the two in the array, and update this with whatever happens with the next drive when it arrives and hopefully passes its tests.Update 5/17/17: fifth drive tested good, and will be a spare, waiting for one of the other drives to die someday. It was packed in a box without any packing material, unlike the other drives i ordered, but it looks to be fine this time.Conclusion, 2 of 5 drives failed testing using seagate tools tests, then dban for multi-pass wipes, then seagate tools again.One of the drives failed the seatools long test quickly. The second only failed the long smart test after being wiped for almost 5 days.As with all drives test them before you put them into service.This is the last update as i am looking for a new job and shouldn't be wasting money on more drives.
