MDD - HGST He10 (HUH721010ALE601) 10TB 7200RPM 128MB Cache SATA 6.0Gb/s 3.5inch Enterprise Hard Drive (Renewed)

I'm using this for video storage on my home server, it's plugged into one slot on one of four USB 3.0 double docks. So far I'm quite happy with it.The drive arrived well packed, clean and pristine. The exterior looked like brand new and the S.M.A.R.T system showed nothing remotely alarming. It's been powered on for between 4 and 5 years, just like the description states.You must format the drive to use it. If you want an entire 10TB partition you have to use something like GPT formatting. GPT comes standard as an option in Windows. Otherwise you have to create several smaller partitions that your disk formatting can handle. Really, if you don't know about this stuff, you probably shouldn't be buying hard drives in the first place but I'm just throwing it in here as a "heads up".This is easily the noisiest drive I own. I'm not complaining because it's not that noisy but compared to the other 7 externally mounted and 8 internally mounted drives I have it's noticeable. It doesn't make that nasty buzzing noise hard drives used to make but more of a muted chuckle as the heads seek. Kind of reminds me of when my coffee pot finishes brewing but much quieter than that. This is not a problem for me as where the drive is located it's not an annoyance or distraction. YMMVThe USB dock where this drive is mounted has no problem powering the drive without the included adapter cable. Which is a good thing because the adapter cable wouldn't work on that sort of mounting connection anyway. If your drive isn't spinning up, this is why. These drives were (claimed to be) tested before shipping and the odds of you getting a totally dead drive are very, very low. It makes no economic sense to ship failed drives. The odds of someone not knowing how to deal with the power configuration of these drives are much, much higher. Exhaust all connection problem possibilities before you declare your drive DOA. Use the included adapter pigtail or try a molex to SATA adapter and then if you can't get it to spin up, you might have a rare but not impossible dead drive. Even though they're tested things can happen in shipping that can kill your drive.The five year warranty is provided by the seller NOT the manufacturer. This is an important distinction that I see at least one reviewer failed to appreciate. HGST/Western Digital is NOT extending the warranty on these drives. If your drive fails within the 5 year warranty period you CANNOT get a replacement under warranty coverages from HGST/Western Digital. Your only remedy is to file a warranty claim with the seller who is NOT an authorized dealer for HGST/Western Digital and does not speak for the manufacturer regarding warranty issues.That said, while we can be fairly certain the manufacturer will still be around in 5 years there's no reason to have a lot of confidence that the seller for your particular drive will still be in business and have a drive to swap with you. Many times companies that pull and swap data center drives are formed ad hoc on the spot just to fulfill a drive replacement contract. The profit from reselling these drives goes into the calculations for bidding the job. In fact the company fulfilling the replacement contract will often sell all the pulls to another company which will test and resell them, then close down after all the drives are sold. This isn't always the case but it's the situation often enough that you need to be aware of it.The point here is that the 5 year warranty is a gamble. While we can all hope that the seller will still be around to honor any warranty they've made -- The truth is that might not be the case.What you're really counting on here is that the drive is rated for 2.5 MILLION HOURS "MTBF" or "Mean Time Between Failures". That means that the average lifespan of these drives is rated for 2,500,000 hours running time.You're relying on the claim that it's been tested and no bad clusters or sectors or other problems have been detected. Whatever the power on hour count might be is an insignificant fraction of that 2,500,000 hours the drive is rated for. It's not uncommon for regular desktop drives to last between 100,000 and 250,000 hours. Even if you get half the 2.5 million hours out of these drives you're still getting significantly longer usable lifetime than you would with a standard desktop drive.That's why you would buy these drives. Not for the warranty.All of that said, the warranty is only a primary concern IF you have a drive go bad and IF you can get the data off of it before it dies. We all know that the cost of drive replacement, which not trivial, is insignificant in comparison to the data loss that occurs when a drive dies unexpectedly.Any machine made by mankind, and any of the components that go into that machine, will eventually fail. You should be using some sort of drive monitoring system or software that either constantly checks drive health or that you use on a regular basis to check your drives.So far, I'm very happy with this drive's capacity, performance and condition. I never thought I'd be able to afford a good drive of 10TB capacity and it turns out that I can thanks to this drive and this seller. As data centers ramp up their storage capacity and swap out drives for "failsafe" reasons we should be seeing even larger long duration drives becoming available and the price should keep dropping.It's great to have enough storage. I'll probably buy more of these in the not too distant future.

2.5 years later working fine, 10 tb hdd purchased no issues using for plex shows up as a normal hdd

This is exactly what I expected. A used enterprise hard drive with several years of poweron hours. The first drive died after a couple days, probably got rattled too much in shipping or something. The amazon return process was very convenient just dropping it off at a wholefoods. They ship out a replacement right away without waiting to receive the old one. The replacement has been working fine for several weeks now.Can't really fault the seller for the fact that a few drives will be DOA once in a while. The main thing is that you get what you pay for and a replacement is sent if needed. Would buy again.Also it's good that they include a sata power cable converter for the drive. I wouldn't have even known I needed it until researching how enterprise drives work. Maybe it should be even more explicit in the description that you need to use the converter, as I see a couple comments saying that the drive didn't power on, which might mean they didn't use the converter cable.UPDATE:After getting a replacement for the first drive that died instantly, the replacement drive died after a few months of use. I don't even know if I could try to get another replacement or refund, and at this point I don't care anymore. I'll just take the loss I guess. My new advice: DON'T GET THIS DRIVE

There is a relatively low failure rate on these, but given the cost, and if you're running them inside of a raid where you have redundancy, that's a very small price to pay for the amount of savings you're getting.This is basically a must buy if you're running a home large storage pool or data lake.

I bought 3 of these for a home NAS. It's one of the best $/TB you can find, and in a density where you don't need a dozen drives. These are refurbished from enterprise data centers, so they have a lot of use, but are a high grade product to start with and have clean sector scans using smartctl, and this seller offers a new 5-year warranty, so I'm satisfied with the liklihood of getting a long life out of them. My home NAS has a pretty light workload anyway.These drives are delivering about 250MByte/sec data transfers on sequential reads, (i.e. with Linux's hdparm -t /dev/sdX) which is better than any of my other spinning drives.One thing not entirely clear from the product description is that the drives are using a new version of the SATA power standard where the pins formerly designated as 3.3v power are now used to perform a hard reset of the drive. This product includes a power connector extension that isolates the 3.3v pins so that you can use the drives even if your power supply has a 3.3v wire (orange). This could be a problem if you have a NAS backplane that supplies 3.3v power. You don't need the special extension if you are using molex-to-sata adapters or if your backplane is powered by 4-pin molex connectors, because the old molex power only has 12v and 5v on it anyway. In fact, I've never seen a drive that actually requires the 3.3v pin to be powered. Anyway, just a detail to be aware of before you buy.
