HGST/Hitachi (HUA723020ALA641) Ultrastar 7K3000 2TB 64MB 7200RPM 3.5" (Enterprise Grade) SATA III 6.0Gb/s Hard Drive

The reason for my 3 stars on longevity is because I've only recently installed this drive in the last few weeks, so I haven't been able to judge its longevity. But, can I say WOW!? We have a backup archive located on an older XP machine with fairly recent motherboard, which can handle SATA II. This hard drive is installed in that machine. I'm using Acronis 11.7 to push backups from various mission-critical computers to this Hitachi hard drive. Here are my observations. First I had a Western Digital Green drive in the place where this new drive is now installed in the hard drive cage. That "green" drive always was a bit slow on backups, anywhere between an hour to 3 hours for a single image to be copied. So I had to spread out my backup schedule so as to not overload the XP computer's max of 10 connections (user sessions). One Acronis backup takes three user sessions in XP, so you can only run three backups at a time (and even that is risky). As you can imagine, to backup the images for 10 mission-critical computers would take days, not just hours. As the green drive aged over the past few years, the backup times got slower and slower, almost as if it was getting too full, even though I managed the space enough to have at least 30% drive space available, even with all backups on board. The aging of the drive sent the backup times into orbit, with 6 to 10 hours needed for just one backup. After about four years from new install until now, the green drives eventually died. I started doing research on what guys were recommending for a good, reliable drive these days, and other than Samsung (with expensive price tag to boot), I saw Hitachi is making some noise with certain lines of their drives in the realm of longevity, efficiency and reliability. Enter this Hitachi drive into my backup schema. WOW, WOW, WOW, images are now only taking a MAX of 34 minutes to perform! Some backups of the C drive image are now transferred in less than 20 minutes! This is across a gigabit network on a SATA II serial drive controller running XP! I'm impressed! So the green drive wasn't a good choice at all, even from the beginning. I knew they suffered on performance a little bit, but I never realized by how much. We're trying to stay economical here, so please don't rag me about XP or using cheap drives, etc. I can't complain too badly, the XP machine has been a breeze to manage, with no security issues at all and the green drive did last about 6 years with 24/7 operation. This little backup rack mounted computer has been reliable as sin. But, the Hitachi blows the old performance away, even with the same motherboard, NIC and SATA controller. I can only imagine what the time saved would be if the PC had a SATA III controller. In any case, I can now run much faster and more frequent backups instead on settling for one-a-week like I did with the old drive. If this drive lasts for 5 to 10 years, it'll be worth every penny. I installed the "green" drive back in 2015, I hope to get slightly longer time out of the Hitachi. MTBF is really no good indicator of real-life longevity for any hard drive, but I think I can rely on the word of lots of professionals who have had good luck recently with Hitachi. So here I am giving it my first whirl in a long time. I do have some old Hitachi EIDE drives, which I believe to this day would probably spin up and perform just fine. Though drives are not made that way anymore, I think Hitachi has proven they know what they are doing when it comes to hard drive manufacturing. (update) 6 months later in January 2020, the drive is still going strong and fast. Backups have not failed once in the last six months, which is a record for this PC. This drive continues to perform very well in our Windows XP backup computer. This computer is dedicated to just doing nothing but making copies of backups to the onboard drives. The computer is a rack mount unit and contains two of these Hitachi drives. We use Acronis to perform the backups. I can't begin to tell you how awful slow it was to back up with Acronis on the old WD Green drives. I'd have to space the backups at least 12 hours apart, and even then, the backups weren't reliable. With the Hitachi drives installed, the backups only take about 20 to 35 minutes to image the C: drive from the host computer across a gigabit network. Very impressive. And we have not missed ONE SINGLE BACKUP since I installed these drives last summer. Which is a historical event for me. Other drives, whether they were WD or Seagate, always had reliability issues. I had always thought it was an Acronis or a Windows issue, but now I know it's not true. It's just lousy HDDs. I feel for the people who have bought these drives and have had duds with them, and that can happen with any platter HDD today, please give them another shot. I had a bad one of these Hitachi drives, too, it lasted a couple of weeks and died, but the Amazon vendor promptly replaced it. The drives have been great. Now comes the long haul, but I thought I would at least update you on the last 6 months with these Hitachi drives, I can't praise them enough for a spindle drive. So far, so good!) 28APR20-Update: Something to keep in mind when doing image backups of your C drives in Windows, make sure you have cleaned up your shadow storage in Windows, cleaned out the temp files in the System 32 directory and set your Windows Backup and Recovery options for as small as you dare. This greatly affects how much storage is used by your image. Your image is going to include all the junk space as well as the obvious usage that Windows reports in the explorer window. So be certain you have this all cleaned up and under control, else you could wind up using your HDD space for backups a lot sooner than you think. I discovered this after having abnormally large hard drive usage in Win7, after I cleaned up the shadow storage through a DOS command line, I was able to shorten the Windows backup and recovery space and re-run my Acronis backups with considerable relief of the backup space used (about 50%), so it's vitally important to conserve your remote backup space with these methods. Now I can use more of the space on these Hitachi drives for more backups for other computers! The drives are still going strong with fast, reliable backups, not a single backup job with Acronis has failed since I installed them in the summer of 2019.

prior to purchasing this, i was informed about studies done on internal harddrives used by many companies and through that, hitachi seems to be the gold standard for longevity or how long the drives lifespan is. many reviews though who have purchased from this line seem to have received old, used drives or completely be dead on arrival.i am very pleased with the drive and the seller. i'm also glad that despite a few 1 star ratings here and there, it did not dissuade me from making a purchase. the package came in excessive bubble wrap, that made the main package bulky. inside was another box with another layer of bubble wrap around the drive itself, and then the non-static packaging. i don't see how any of the drives delivered or shipped this way could be used or old, my drive seemed brand new.on the drive itself- i don't see why reviewers state it's loud and excessive. it's dead silent....does not make any noise or sound, and seems to run very cool.- the drive itself i believe winds itself down when not in use so in essence it isn't being read by the computer 24/7 which i believe contributes to it's lifespan. but when you do attempt to access it, it does take a few seconds to load back up, which is logical.- the drive copies very quickly, i can't see for a need to have greater speeds than this. this is probably the most affordable / quality drive in the market.- the drive uses about 19 gigs out of it's 2tb availability.

Because I didn't have any problems with the seller and the HDD is cheap, it receives 4 stars. Its pretty fast for a 7200RPM drive, i think its reliable, but my only complaint is that its really loud. When things write or get read from the drive, the drive vibrates like crazy. I replaced it with a Seagate HHSD and that drive is much quieter. Online I read that Hitachi holds the reputation for being the most reliable drive, so I keep this Hitachi as my system backup drive. If you don't care for the sound though, this is a great drive.

I replaced a failed drive in my ZFS array. easy fix.

I purchased other Hitachi products before, but the build of this one that I received seemed less sturdy than I had anticipated for this type of drive. Ended up returning it and opting for another drive that was more well-reviewed and higher-rated.

Pros: Plenty of space, had never power cycled before I used it, actual Hitachi hard drive (not rebranded HGST), fairly cheap for price.Cons: Can be loud when reading/writing intensively. But perfectly fine for a large Steam library, music library, video library, etc.Other thoughts: If using on a desktop computer with Windows, please look up "Symbolic Links" and "Directory Junctions". It'll make installing games easy, since it'll redirect "C:\Steam" to "D:\Steam" (example), so you'll never have to modify the installation directory again (nor worry about registry problems). You can also do the same for certain programs (like game mod management tools), music and video libraries, etc. Symbolic links mean you can have folders that open in different devices (like hard drives or SSDs), but that all appear to have the same directory ("C:\Steam" for example) even though the files are located on the hard drive. This makes keeping your OS on an SSD and your game libraries on an HDD much simpler and better. It'll save you time, be more convenient, and you won't have to move files around or tinker about with the registry (nor reinstall or repair existing installations of games or other programs).

Es un dos termas con muy buenas referencias. La velocidad de acceso normal. Pero hace un ruido terrible....

Ho acquistato questo prodotto ricondizionato ed ha le stesse prestazioni di uno nuovo, sia il lettura che in scrittura, molto silenzioso e perfromante.

Disque conforme, facile à installé. RAS

Fantastic Hard Drive works very well and a really great price

Looks like a good solid drive. I have it in an enclosure and plan to use it as a backup drive. It mounted up OK and formatted with no problem. It is quiet but did make a rapid clacking noise on occasion while formatting and running Chkdsk. These drives are rated highly for reliability so I'm hoping it outlives the WD My Passport that I was using for backup - it only lasted a few months. I did learn one thing from the experience - the drive warranty is meaningless on a backup drive. If you have a bunch of data on a drive that has failed and you cannot erase it, do you really want to send it back to the manufacturer as a RMA?
