2 out of 5 eggsHitachi 4TB SATA Internal Drive Problem

Pros: The Hitachi 4TB Drive is what I was looking to put Inside of My Custom Built Computer, because I'm running out of Storage space.

The Specs of this Drive are Really Great.

Cons: I have been trying to get this Hitachi 4TB Internal Drive to Initialize and then Format so I can Use it. I was able to get it to Initialize, but Not Format, because when I select it, My Computer Locks Up and I can NOT do ANYTHING at all. When I disconnect the power to the Drive, then My computer works just fine. If I connect the power and Boot Up My computer, then it just hangs in the Boot process and does NOT finish the Boot Process.

I'm about ready to call Hitachi and get Tech Support on the phone to see about either Helping Me to get the Drive to show up, or have Tech Support switch Me over to the RMA Department.

4 out of 5 eggsNo issues so far

Pros: - Huge capacity
- First 4TB drive to market
- They run cooler than my previous Barracuda 1.5TB disks
- Rated for 24x7 use (though don't mistake these for "enterprise" class drives)

Cons: - Lots of other people are reporting problems (mainly high infant mortality rates).

Other Thoughts: For the last two months I've had 6 of these drives in a RAID array on an Areca ARC-1280ML (w/ 4GB BBU cache), under what I would call "medium duty" usage. Not a single problem so far, and great performance. I've been monitoring SMART stats with Hard Disk Sentinel and haven't yet seen any reallocated sectors. Temperatures stay around 35°C; and have never exceeded 42 (with push-pull cooling). The drives are just as quiet as any other modern HDD.

Taking other reviews into account, I suggest you take the time to break in new disks (exercise them with a period of intense reads/writes to weed out any premature failures) and then install them in mirrored, RAID6 or RAID-Z3 configuration. Array rebuild times for 4TB disks are huge; don't go RAID5 with consumer disks (Google "RAID 5 URE" for why).

Based on my own experience, if you heed the advice above, I see no reason to avoid this brand. All 4TB models are new and it will take time before any meaningful "in the field" reliability metrics are known. The seemingly-high DOA rate (especially on RMA replacements) is a cause for concern, but keep in mind users with negative experience are far more likely to leave feedback and those who are chugging along just fine.

1 out of 5 eggsBuyer Beware

Pros: -> Large Size
-> Hitachi Brand
-> mostly good reviews...

Cons: -> Direct experience on High death rate
-> This will be my 3rd drive in less than 9 months!!
-> Last replacement lasted barely 6 months!
-> People are not exaggerating about these drives.
-> I have purchased Hitachi drives for 15+ years and I have NEVER NEVER had a drive with this sort of reliability issue. The drive works for a while, then refuses to spin up. This 2nd drive is now presenting the SAME symptom as the first time it was replaced.
-> Googling around show this to be a common and widespread issue.
-> In my case, this drive is barely being used, just a few files here and there and it's staying cool and not overheating... so I'm not sure what the problem is. I have another 2TB Hitachi right beside this one and it's been running like a champ for several years with no so much as a whimper...
-> If Hitachi ships me another bum drive that fails again before it should, then this will be my last 4 TB Hitachi drive and possibly last Hitachi drive ever.
-> With all the problems being reported, Hitachi should offer its customers an option of refund or or ship a newer model or something which works.

Other Thoughts: -> Anyone considering this drive, should think twice if they value their data, their time, costs and the hassles with shipping these back to Hitachi for replacement again and again.

3 out of 5 eggsReviewers who don't know a bad drive when they see it.

Pros: Price, transfer speed

Cons: High infant mortality rate - some drives DOA, some make strange noises, others have lots and lots of bad/unrecoverable sectors near the inner tracks. In other words, even when a drive passes extensive tests prior to putting them into production, you often find out that as the drive fills up with data, the last 10 to 15 percent of the disk has lots of bad sectors. This obviously means that the ferrous oxide coating was applied unevenly.

Other Thoughts: To the reviewers below who reported 11 and 25MBps data transfer speeds. If it's an internal drive in your computer, and you get anything less than 100MBps, you have a bad drive.

If it's an external drive attached to a USB 2.0 port, you are limited by the slow USB 2.0 interface.

If it's an external drive attached to a USB 3.0 port, and you get less than 80-100MBps, it's a bad drive.

If you're using it in a NAS box attached via Ethernet, make sure it's a Gigabit connection, not 100-Base-T. Gigabit connections max out at 120MBps (although it is rare to max out a gigabit link on a NAS box). If it's a 100-Base-T connection (also known as Fast Ethernet), you'll max out at 12MBps.

No matter how your drive is connected, you MUST do extensive tests prior to putting the drive into production. That means completely fill the drive with data and observe the data transfer speed - drive will gradually slow down as it reaches the inner tracks. Then copy all the data back to another drive to ensure that the data can be read once it has been written. Then erase the drive and repeat the full write/read-back test a second time. Only then will you have confidence that the drive is truly a good one.

Any noises or clicking sounds you hear during the test phase will only get worse over time. Best to RMA noisy drives even if they seem to pass the initial test phase.

Finally, during the write/read-back tests, if you notice that sometimes the drive is transfering data at a speedy rate, then occasionally slows down dramatically, then speeds up again - this is an indication of weak/bad sectors. When the metal oxide coasting is applied unevenly to a platter, the result is a drive that passes the initial test at the factory, but isn't one you would want to own.


These days, two drives in a RAID1 configuration is the minimum to ensure that you don't lose your data. Three to 8 drives should use RAID5. And 8 or more drives should use RAID6 for a second level of redundancy. Yes, you will have to buy an expensive controller card to get RAID6, but if you are serious about preserving your audio or video collection, not to mention priceless family photos, you MUST accept the fact that every hard drive in the world will eventually fail, and you never know it will happen. If you are using a single hard drive of any capacity, large or small, to store data that is precious to you, you are being terribly foolish.

I have purchased hundreds of hard drives in the last few years from all the major manufacturers, and used them for RAID6 arrays in corporate environments. Trust me when I tell you that if you skip the test phase I described above, you WILL lose data at the worst possible time.

4 out of 5 eggsCheap, big, slow

Pros: Huge size is great for backups and the price is very cheap compared to buying Network Attached Storage. It didn't arrive DOA.

Cons: 11.5 MB/sec write speed is very slow but since I'm using it just for backups it's not a big deal. I wouldn't use it as a primary work drive.

2 out of 5 eggsHigh DOA rate

Pros: Lots of storage space, with decent (100MB/sec+) read/write speeds. Once I found working drives, no other issues encountered so far. I use these in a RAID configuration for a home rolled HTPC (Ceton InfiniTV 4). They are able to keep up with 4 simultaneous recordings, as well as playback to 3 extenders at the same time.

Cons: Bought 2 of these, and had to RMA 9! (yes, NINE) drives to find 2 working drives. All of them just clicked like they couldn't access the platters. I don't know what the root cause problem is, but there is NO reason that I should have to go through 11 drives to get 2 working. Poor quality assurance. I want more, but will definitely wait for the next generation of drives to correct the DOA issues.

3 out of 5 eggshuge drive priced reasonably

Pros: very large drive for a reasonable price with expected performance. sustained 120 - 125 MB/s read / write (non sequential) writing 2GB files roughly 10x using AJA System Test.

Cons: two out of the three drives arrived DOA. sounded like the head wasn't able to get out over the plates, just repeated clicking sounds. immediately packed them up and sent back to Newegg for RMA.

disappointed at the 66% failure rate but i'm assuming something drastic must have happened either with shipping or storage to account for those failures. otherwise have read these drives do not fail nearly as often.

Other Thoughts: these are being used for offline archives in production so admittedly these are not being put through their paces to evaluate performance and longevity. roughly 4TB's of data are being written to them, duplicated, then sealed up into a pelican case until the inevitable. however, during the 1-2 days of data dumping they do operate at relatively cool temperatures and perform as expected.

i'd consider using these in an HTPC environment with a software raid 1. even at uncompressed blu ray / 1920 @ 60 fields a second your read speeds will be fine on these. just be careful, all drives inevitably fail and unfortunately these seemed to be a statistical anomaly!

another reviewer stated 20-25MB/s read / write and i am simply unable to recreate that performance level.

2 out of 5 eggsslow slow slow

Pros: high cap - low price

Cons: slow -- i get about 25 MB/s transfer rate to them. that is right, transferring my film collection to the new pair of these formatted together for 3.7T. the entire 3.7 Terabyte collection is taking 1 Day and 17 hours to copy all the files. I spent TWO days, trying them in Dynamic, Raid, etc -- they are just slow. bout as fast as floppies

Other Thoughts: i am suing a I7 EXTREME on a Fatal1ty X79 mobo -- all the other drives xfer to and from each other at 180-230 MB/s -- except these babies.
