First time working with used drives, but costs have gotten so high I figured it was a good time to given them a try. Order two of them and so happy with them I order two more :) Have them in a home server running 24/7 and no issues for the past 6 months. Would definitely keep them in mind for my next drive needs.

I ordered 6 for a 4 bay NAS figuring at least one would be DOA and to keep one as a spare since it was such a good price. 1/6 was DOA sounded like maybe an actuator was bad tough to tell if it was due to shipping.They are shipped in antistatic bags in plastic shock resistant harddrive caddys in a cardboard box. SMART data is consistent with their description. Lowest time on for me was 29000 hours average seemed to be around 32000. Power cycles were low on all about 20. Extended tests on the 5 working drives all showed healthy without any bad sectors or incorrectables.Great deal for enterprise drives with a great warranty. These work well for those that have some fault tolerance so that if you do need to use the warranty it’s not a big deal. At 5 years I am expecting to RMA at least 2 but that is not a problem with my fault tolerance. I’m still spending much less money than buying new.Thanks goHarddrive!

As a recent purchaser of the Helium Platform Enterprise Hard Disk Drives for my customized computer, I am thoroughly impressed with their performance and reliability. These drives have seamlessly integrated into my system and have exceeded my expectations in terms of speed and durability. Their high-density storage and optimized data transfer rates ensure efficient operation, even with heavy workloads. The helium-sealed design not only enhances reliability but also contributes to quieter operation, which is a bonus. Overall, these drives have proven to be a valuable addition to my setup, offering the performance and reliability required for my demanding computing needs. Highly recommended for anyone in search of top-notch storage solutions for their enterprise setup.

Seemed to be packed well, and in good shape. Worked for a few days, then failed in the middle of a 'save' operation and wasn't even recognized by my computer's BIOS. Returned for full refund.

I've been running 4 of these drives in my NAS (RAID-10 array) for about a month running low-bandwidth but consistent read-write workloads(aka no drive sleep), as well as some burst read-write workloads.Unfortunately my sample size is too low and too short to make any assumptions, but all drives passed my initial tests, and reported no SMART errors thus far.I am wary of cheap drives, but these are reasonably fast and cheap. I would say if you wish to purchase this product, make sure you have a good backup plan in place (RAID is not a backup).Only thing that makes my wary is that these drives are abnormally loud when compared to my experience with enterprise drives, however I'm unsure if the drive noises are 'normal' for this model or early signs of failure. Although you probably won't notice this externally unless you try to listen.I will update this review occasionally to provide feedback as time passes. But these drives appear good.3 month update: No drives failed, still noisy, but fully functional with no issues.

Great volume for a great price, if you're willing to roll the dice. I bought (4) 12TB drives for a RAID5. They arrived well packaged in separate boxes with a SATA to SATA cable in each one. Literature in each box explains that these drives have a remote power disable function, and that the included cable may be required if your system does not support this feature.Unfortunately, one of them arrived DOA (click of death, not detected by BIOS or seen in windows disk mngr when placed in a USB cradle. Another, while working, makes a disturbing grinding noise when it spins up. MDTech's support is fair enough, but they have to get the drive in hand before they'll ship the replacement. I know this is pretty normal, but now I get to wait a week or so, AND visit the delightful people at the local post office to get it sent back.I knew I was buying used drives and there is some risk. I suppose 'three outta four ain't bad'... but my project is now in limbo.

I used 4 of these drives in my TerraMaster NAS. They have been working flawlessly to back up the hard drives in my 3 computers for the past 3 or 4 months. Their In-service hours (reported by S.M.A.R.T.) seemed rather high, but none of the drives have not exhibited any problems and have no bad sectors.

Drive shows 100% health, only 23.5K hrs on it. Wicked fast shipping (overnighted from Florida to Maine). Great drive for backup or data hoarding, not that fastest or most responsive drive but great for bulk backup. Helium drives are noisy when the heads move and formatted capacity is 10.9TB. Super happy with the purchase! I'd have no problem loading a NAS with a bunch of these.If you don't see this updated there has been no change in the drive since this review was posted.
