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

PROs Purchased 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.

It's a quiet hum. I couldn't get it to initialize and got really frustrated. Connect 5 different ways and it didn't show up. Put it in the box to send back, did some reading and decided for one last try. Stuck it in the caddy and off it went. Win10 still popped up a "I-don't-see-u box" but it's there. Copied some files and it's really fast. Smart was wiped, only 72 hours on it and 38 starts. May 2019 MFg so worst case, it's 16000 hours. Crystal disk likes it.

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!!!!

Purchased this 5x tested all 5 drives. all 5 passed 0 bad sectors and no issues with smart test. however when I purchased them they mentioned having the power disable adapter and even the instructions say use the included power disable adapter. In 5 drives I only got 1. Not the end of the world but some thing to keep in mind. also only 1 drive was above the average 5 or so years at 6.5980 years now time will tell but I do buy these drives and so far good luck and good drives. good value for money They do include instructions for power disable and include kapton tape so +1 for them.

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!!

bought two. ONE makes an annoying sound, like a slow rythmic "brrt......brrt........" MOST of the time, but can only hear it if room is really quiet. and once i moved my computer below the desk, i never notice the sound. the other one is totally silent all the time. these drives are fast, and my computer and software always cooperates well with them. which is what is expected. love the huge size. of course, MUST use the power adapter cord to, not sure about what it is or whatever - the normal power cord in a computer plugged into some other "older" looking connection, or whatever. ONLY 4 months i've used them! hope they remain working for a long time! we'll see! ....but, there IS a 3 year warranty, right?? i think i saw that in the details. anyway, later people

Multiple buys. Some problems but seller made it right.

I have been using these HGST refurb drives for years and never had one fail... until now. I hooked it up and it showed up weird. I use a third party disk utility since windows is so weak and it showed two drives with 0.00 space available. this, right out of the box. Played with it for a while but got nothing but weird error messages of various sorts. was never able to get it to been seen like it was supposed to. This time i did a replacement rather than a refund because i figure i just got a lemon. Got an exact replacement. didn't work either. started to troublshoot and it turns out that the first one may have had a bad power adapter they included to use with non-power disable systems (which my system does support power disable but i do not need it) It melted one of the wires on my power supply molex adapter. When i used a good supply cable and the adapter that came with the new unit, it worked. so keeping it. the problem with this kind of refurb stuff is that unless you get it from the manuf, these third-party people do not always know what they are doing.
