    OK, but they tweaked the internal counters

    3/5 rob - See all my reviews Verified Purchase(What's this?) This review is from: Hitachi Ultrastar A7K3000 2TB 64MB Cache 7200RPM SATA III (6.0Gb/s) Enterprise 3.5-Inch Hard Drive (HUA723020ALA641 (0F12470)) (Certified Refurbished) (Electronics) The drive works fine, everything is OK, but they WIPED the S.M.A.R.T. data, so the power on time shows fresh, but they didn't hide the self tests, the last of which was completed at about runtime hour 23000, so these are very old well used drives, better be a part of a redundant array or something. It would be silly to depend on one of these. Help other customers find the most helpful reviews  Was this review helpful to you? , October 10, 2016

    SMART reported 0 Power_On_Hours

The logged tests had all passed, though. I ran a full disk write test overnight, which also passed. So far, no problems, and I have self tests (nightly short, weekly long) running automatically with no errors after over 1100 powered-on hours in my own system. Good value for the price, and I spent a few dollars on a SquareTrade plan just in case: SquareTrade 2-Year PC Peripherals Protection Plan ($0-$50).

    Not new at all: Used 15,123 hours in the past

    1/5 Unda (France) - See all my reviews Verified Purchase(What's this?) This review is from: Seagate Barracuda 1TB 3.5-Inch 7200RPM 32MB Cache SATA 6.0Gb/s Internal Desktop Hard Drive (Electronics) This is a fraud!! This hard drive is NOT NEW AT ALL. And not only "not really new", this has been used 15,123 hours in the past (internal drive data)! It goes without saying that this hard drive has probably spent 1.7 years in a server, running 24/7, and thus has a much higher chance of failure than a brand new one. I'm going to contact Amazon about that and will update the review accordingly, but those hard drives definitely are refurbished ones., March 26, 2015

    goHardDrive - no mfg warranty, 1yr vendor warranty

    Product Comments:Product itself is high quality, sequential write for empty disk tops out at 150+MB/s at the outside down to about 115MB/s at the inside of the spindles. The disk is an enterprise drive and has no Acoustic Management; when you have random read/writes the heads repositioning is noticeably audible.Seller Comments:Seller - goHardDriveAll interaction with the seller was excellent, however:Drives have 1 year _Vendor_ warranty. Checking the serial at HGST yields a response to contact the vendor, ie. no manufacturer warranty.Both drives I received had previous SMART self tests at 8000-9000 hours, yet drive reports 0 hours of service. All other SMART data was clear leading me to wonder these drives have been previously used and cleared by TTL command.Single drives from seller come in small USPS Priority Mail box with double layer of bubble wrap and sealed anti-static bag, this is a bit sparse on padding.

    Another great Hitachi drive and quiet too.

    5/5 NOLAexpat (WINDERMERE, FL, US) - See all my reviews Verified Purchase(What's this?) This review is from: Seagate Barracuda 1TB 3.5-Inch 7200RPM 32MB Cache SATA 6.0Gb/s Internal Desktop Hard Drive (Electronics) Shipped quickly and even delivered early. Great status updates from seller and Amazon as always. Hitachi drives are the absolute best and I really won't use anything else but i was a bit hesitant to order the Ultrastar as i assumed it would be noisy since it's an enterprise class drive but i was wrong. This drive actually spins up and runs maybe even a little quieter than my other desktop drives. There is no whine and i really can't hear the arms during access at all. It formatted 100% with zero bad sectors and is working great. I would recommend this drive for any application.

    Not "new" as described

    2/5 J. Murphy - See all my reviews Verified Purchase(What's this?) This review is from: HITACHI 0F10452 2.0TB SATA 3.0Gb/s 7200 RPM 32MB Buffer Hard Drive Bulk (Electronics) Unit was described as "new" and "OEM Pull". Well, the OEM pull part is true. The drive I got in August 2014 was made in October 2010. The "new" part - not so true. S.M.A.R.T. data show 28,465 hours of use and 79 power cycles. It looks like this drive was pulled from a data center or server where it was used 24/7 for the last 4 years. Two stars because the unit is, for the moment, working perfectly. But I will probably return it or ask for a replacement, as I do not want to rely on such an old drive for the PC I am repairing.

    1 of 2 is bad (not able to create a partition)

    Another time the quote: “You get what you pay for” become very true. 2TB for $69.95 per each did not ring the bell loud enough, or I didn’t want to hear it. Also I was not careful and I did not read the feedback (refer to the review provided by another unlucky customer on August 11, 2014).I purchased 2 Hard Drives. Both of them are extremely loud, 1 of 2 is bad (not able to create a partition). Both drives were manufactured in December 2009, yes – only 5 years old. There were used (probably working 24/7 on some server – but this statement is only my guess, other statement are facts). The drives were sold by New World IT. I’ve just requested a return and refund for these 2 drives (1 completely defective). Waiting for confirmation from the seller (again - New World IT).

    LOUD

    2/5 Nonentity - See all my reviews Verified Purchase(What's this?) This review is from: HITACHI 0F10452 2.0TB SATA 3.0Gb/s 7200 RPM 32MB Buffer Hard Drive Bulk (Electronics) It makes a horrid sound and read/writes at about 60mb/s. Had to format it myself which took about an hour or two. (Two terabytes is a lot to format). Sounds like someone rolling around on a creaky bed. I'm afraid it's going to snap the actuator arm in half or something, it's so loud. My friend said to not buy Hitachi and I see now why it was so cheap...

This review is from: Hitachi Ultrastar A7K2000 2TB 3Gb/s SATA 7200RPM 32MB Internal HDD Hard Drive (Certified Refurbished) (Electronics) This drive has multiple re-sellers, I made sure to purchase from goHardDrive. This is even mentioned in the item description. Drive arrived 3 days early and in perfect condition. Ran two full tests (which kept my computer and the drive active constantly for over 30 hours). Passed 100% with both the HGST/Hitachi tools and Seagate's SeaTools software. No faulty sectors, as advertised.Very pleased with the quietness of lack of vibrations from this drive. No issues installing the drive, and while I think it could have been packaged better for transit (antistatic bag, wrapped in a layer of bubble wrap and put into a flat rate USPS box that was too small, then put into a Priority Mail envelope.); the drive arrived with no damage.

    I am happy with these

    I have two of these drives for my desktop, one for games, and the other for media, and both have worked very well. I am happy with these, as well as the price. Only difficulty is finding a reasonably priced backup drive to use, as I now have close to 5 TB of storage space, and 5 TB drives run over $100.I tested it at ~125MB/s sequential write, but in practice I cannot reach those speeds. Coming from a gigabit connection at my old place (and getting gigabit in a week or so at my new one), Steam would frequently have to stop downloading because the hard drive couldn't keep up, limiting my download speed to ~25-30MB/s, and often dropping to zero while the drive writes and unpacks. This is not an issue on my SSDs, where Steam has reached 75-90MB/s. However, considering I have ~190 Steam games, and about 160 are currently installed on one drive and ready to play at a moment's notice, I consider this a EXTREMELY small inconvenience.As others have said, it is quite... 5/5 Brian A. - See all my reviews Verified Purchase(What's this?)

    Great for its Price

    5/5 kmind (USA) - See all my reviews Verified Purchase(What's this?) This review is from: HITACHI 2TB SATA 7.2K 3G 3.5 (Personal Computers) This hard drive is great for its price.It's the cheapest 2tb hard drive on the market, its life-span is large, and its performance is bearable. It is definitely my go-to HDD.I highly recommend coupling this with an SSD, else you may have some dissatisfaction with the lengthy PC boot-up time and transferring of large files.The only drawback I have is the noise. If you're one of those people that must have your computer as quiet as possible, then perhaps you should rethink this purchase. It isn't loud - at most it makes a quiet murmuring. I found that when wearing headphones, I couldn't hear it at all.Overall, this hard drive is great for mass storage. Installing your OS on an SSD and using this for storage, it's hard for me to find anything negative about it. If you require the disk space, then I highly recommend this Hitachi hard drive.

    Best Hard Drive For The Price

    5/5 Kyler Greenway - See all my reviews Verified Purchase(What's this?) This review is from: HITACHI 2TB SATA 7.2K 3G 3.5 (Personal Computers) To simply put it, I truly love this hard drive. Back in December of 2015 I build a custom gaming pc. In the pc I had a 2tb western digital hard drive, however I was quite saddened when just after 4 months of use my WD hard drive completely died. My fix to the solution was purchasing the Hitachi 2tb hard drive that I am doing this review on. Have been using the hard drive for 6 months now and have had no issues what so ever. I also think that it runs a little bit faster than my old hard drive is well as it was also cheaper. Can't get a better hard drive for the price!
