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!

My main storage drive. Absolutely massive though it does take a while to spin up and large files will not open on it in an expedient fashion. That’s not what this drive is mean for. If you want to store bulk media files and documents this is the drive for you

There's nothing wrong with the basic functionality of reading and writing, but it's really noisy. It comes in a documentary bag that can barely absorb shock, and I can't say it's a direct cause of the noise, but it's definitely a pretty frustrating situation.

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.

Item description is simply WRONG: "Bare Drive Only, Single Pack, (No Screws, Cables or Accessories included)" When I unpacked it (very securely packaged, btw), there was a cable included. I only glanced at it and set it aside, as the description had very clearly said no cables were to be included. What's more, I only wanted to replace an existing SATA drive with this one, so any required cables were already in place. Hooked up the data and power - nada. Win11 wouldn't see it, BIOS wouldn't see it, no indication the drive was even spinning up. Read a few reviews - a disproportionate number of DOAs. Hmmm. Tried it in another PC by replacing an existing, functional SATA drive. Same outcome. Apparently DOA. Took a look at the cable which had been (superfluously?) included. It was a power converter cable from traditional IDE power to SATA power. Rummaged around to find a legacy 4-pin IDE power cable in my bag of power supply adapter cables. Wired this directly from the power supply to the converter cable and plugged the converter cable into the SATA power port on the drive. Bingo! All it would have taken is for the seller to include a small piece of paper annotating the need to USE the included converter cable - and a correct description on Amazon in the first place. I know HD manufacturers do this, but when you buy a 12TB drive, it instantly sucks part of the joy away when it formats down to 10.9TB. That's a BIG conceptual "loss".

Used 3rd party software to check the integrity of the the hard drive and there were no bad sectors/blocks/bytes. These enterprise drives usually are only written on once, and spend the rest of their lifetime reading data.. meaning that they are in excellent condition and will usually outlast a brand new consumer grade drive. Been using this in my plex server and its been on for over 60 days straight with zero issues.

Loving these in my NAS. I was a little worried about used enterprise drives, but so far so good.

Complete hit or miss on these. I bought one 6+ months ago for $148, and now’s it’s $300!!! One before that failed after 1yr. Gimme a break, it’s a refurbished drive!!!! Mine died 3 months into use. This price hike has nothing to do with tarrifs, just a reason for sellers to raise cost. I can but a NEW Ironwolf for $350.
