HGST Ultrastar He10 | HUH721010ALE600 (0F27452) | Power Disable | 10TB SATA 6.0Gb/s 7200 RPM 256MB Cache 3.5in HDD | 512e | Enterprise Hard Drive (Renewed)

I had my doubts with some few negative feedback on the item, but I had faith in knowing decades of previous machines I had built on Hitachi drives.Upon arrival and installation, i was pleasantly relieved that it worked great right out of the box. Unlike previous drives, I did have to use the dongle adapter to bypass the new remote power down system standards, but once I did, it registered immediately and formatted fine. Tested rigorously three times using surface tests overnight.100% functional no bad sectors nor a single error warnings. Proceeded to copy my old drive and it was going at 180mb/s during that write process.Overall a great unit.Read head clicking is somewhat more noticeable in random read operation but that’s been normal for most modern Hitachi HGST drives.Heat properties are fine too. File copying took 3 hours, for 3.5GB of information. No warnings for heat related issues and PC fans stayed nice and stable.10Gb is a lot of storage! $78, Hitachi drive quality, I will take it!!

PROsPurchased 6 drives all were 10TB HUH721010ALE600, have firmware LHACT38Q.Average of power on 8067 hours or 336 days and 3 hours. Lowest received was 501 hours (20 .875 days) most were in the range of 9500 hours. Power cycle count was between 16-17 when I received drives.All passed extended 18-hour SMART battery of tests.☼ Quiet☼ Looks to be and feels to be in good shape, clean.☼ Synology RS1221+ recognizes and works with them, it doesn't complain about these drives as many RS and XS series can and do, I've been very fortunate in my cautious selections to use.I've included this to assist other Synology owners with this specific model in locating working drives -( as of 10-27-2023. /w DSM 7.2-64570 x. )If all turns out well, I'll be bookmarking this seller and watching offerings.Caution to NAS owners. I don't care what drive source you use, make sure if it's worth keeping have several tried and tested backup plans to fall back on, anything can die for any reason.CON:►►I don't recall seeing any power cables in my 6 boxes but as advertised, however, might be nice to have for a future use when a system won't handle these drives natively.▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬Initially, I started out using:WD Red Pros, after 5 years of running they still have no issues and are still in service.I added Seagate Iron Wolf Pros, after 2 years of running no issues, still in service.Now adding WD/HGSTs. - they're looking promising.(Have tried WD Gold Enterprise, those things are tanks but expensive.)I'm keeping the Red Pros and Iron Wolf Pros engaged as I integrate these HGSTs and start stressing them just in case, though I'm bit more that optimistic now than before and hope I've found a reputable source that doesn't deal in garbage.03-14-2024 Update - Still going strong on all 6 drives with 24/7 operation in NAS, no errors on RAID5 patrols and things seem to be quite happy. Going strong for the rest the of the mentioned WDs and SGs too.

I was not that bothered by the speed since I use this only for backup and it spends 29 days a month powered off, then 1 day powered on for backups.... but...I have been moving data onto this drive and I can tell you this is NOT an enterprise drive. This is a HOME drive and the knocking noises I hear inside this drive scare me. I would be worried that ANY drive made as many knocking noises as these heads do as they are moving around. It sounds like a fan spinning inside and its getting hit by a cord or string and as it bounces around and drops back into the fan again and again it makes another knock. To me.. the knocking noises are very upsetting since I have 8 of the TRUE HGST 10TB drives that are in the same JBOD box and they are all silent doing the exact same job. Only these (2) drives make these noises.I will be boxing and returning these as soon as I find a replacement. It seems maybe the HGST drives are "almost" or "completely" gone and WD is going to capitalize on the reputation for quality to sell their cheaply made drives. Since My original 4TB HGST drives (16 of them) NEVER failed me in 6 years. i have been replaceing them with these 10TB drives, but.. there is no way I can trust a drive that sounds like something is bouncing around inside to last like my real HGST drives did. I only have 8 of the real drives and I will be looking for some remaining "old" stock of them and when I find them, I will send these back. These are not broken but they are such inferior quality to my original HGST drives, that they would drive me crazy. I heard them knocking as I walked by.. while my fan was on and making noise!!!!

These drive were installed in a Synology DS220j NAS and all 4 drives reported healthy at 9.1TB which is normal for a mfr advertised 10TB HDD.Upon initial installation the drive was reported as not on Synologies approved list, but the drives work fine in all respects in the NAS.A little noisy but Ive heard worse. I have it near my working desk and I dont mind the noise in fact its a reminder things are working.It fit perfectly in the Synology into its slot and connected with the mating connectors.The adapter cables that came with the kit were not needed for my case.They were packaged nicely in sealed containers, very professional.
