Hitachi 4TB CoolSpin - $274.95 shipped

We at Greenleaf have tested this very drive on a multitude of hardware, including the popular Supermicro AOC-SASLP-MV8 and Monoprice SIL3132 SATA controllers as well as a long list of motherboards.  The drive (and the other hardware) passed every test.  You do have to use a beta version of unRAID (we used unRAID 5.0-beta-14).  Check the Greenleaf Hardware and Software Blog in a few days for the full report.  If you've been itching to try a 4TB drive, I say go for it!

That's awesome, thanks! Been running 5.0b13 for over 4 months w/ success so have not upgraded to 14 yet, but will update to 5.0 official once released. Have been selling off my Win7Pro surplus to save up for some 4TBs (will be going to Win8 instead in the near future). Still have one left at this moment (8 sold) if anybody is interested. ebay

What's the speed on this puppy on the outer tracks?

 

What's the speed on this puppy on the outer tracks?

 

About 120-125 MiB/sec ... if you test it on the SiI3132 :) .

 

Seriously, I'd be interested too.

 

[When attached to a modern controller], try:

hdparm -t --direct /dev/sdX

 

Thanks.

Hmmm, I would have expected more speed.

But not if it is connected to/controlled by a SiI3132 (as one of the two "validated" controllers by Rajahal).

Full Hitachi 4 TB hard drive review is published! Check it out in the Greenleaf Hardware and Software Blog! A big thanks to UhClem and WeeboTech for your suggestions as to performance tests to run...you'll find the full results to all requested tests in the review. Enjoy!

Excellent article! Thanks for the benchmarks. Seems to perform well.

[ To borrow a phrase :) ] :

Hmmm, I would have expected more speed.

On the hdparm test, my 5K3000 2TB does 131.07 MB/sec -- and that is a 667GB/platter drive, vs the subject 5K4000 4TB, which, at minimum, is a 800GB/platter drive. Rajahal, if you still have it, and also have an accurate scale, could you provide its bare weight in grams. (I still have not found a reputable source for whether it is 5 or 4 platters, and a weight might allow for accurately deducing it.)

 

Aside (to Weebo): Did you not find any inaccuracy in the review's description of your test script?

 

Thanks, Rajahal, for the early glimpse.

I noticed an error, a couple times it mentions 30GB of data, when the test only runs up to 10GB.

Raj, you will need to adjust that.

 

 

Raj if you still have the drive, can you test it on A windows machine with hdtune (read only mode is sufficient).

It peaked near 140MB/s, but I would have expected it to be around 145-150 at it's peak.

In any case it's still a sweet drive to own. The only thing that concerns me is how much data loss could occur if the drive goes bad.

lol, I know right?  My current server itself is only 6.5tb.  Can't wait for these to drop in price.

Thank you Weebo and UhClem for the feedback!

So the it tests the same outer-most 10 GB of the platter over and over?  It doesn't progress inwards on the platter at all?  If that's the case, then I don't understand why the speed drops so systematically.  I certainly want to correct the mistake and my mis-understanding of the writeread test.

I don't have the drive anymore, but I believe prostuff1 still does (unless he has already shipped it to the customer).  I'll pass along these requests.

I Also noticed your SSD was benching at only SATAII speeds for a SATAIII drive. I ran the same tests on mine and was closer to the 480MB/s  mark

Yes, I believe the SSD was being run through a SATA II controller.  Good catch.

For anyone wondering and for those that asked:

 

1. I do still have the drive and have weighed it.  It weighed in at 693 grams

 

2. I was finally able to get UBCd4win loaded via USB so I could test with HD Tune as requested.  The drive specked at:

Low: 112 MB/sec
High: 141.9 MB/sec
Average: 131.6 MB/sec

Access Time: 9.1 ms
Peak: 203.3 MB/sec
CPU Usage: 5.2%

 

Hope that helps everyone and answer the questions asked.

One would need at  the very least 2 of these to take advantage of the capacity!!! With the price of HDs at the moment it's rich!!! :(

Especially considering that 3TB drives are going for about $140 now and as low as $115 with some (coupon) effort!

Awesome, thanks Raj!

 

Thanks to prostuff1! He did most of the performance testing.

Not a problem.

 

The real thanks goes to Trevor for allowing us to test the drive and being patient while we did so.
