Toshiba HDKPC08 3T Drive

[lionelhutz]

NCIX.ca is running a sale on these for $129 and they reportedly have a 2 year warranty. What the heck is the story with Toshiba HDD? I thought they were bought by Hitachi and then WD bought Hitachi. I went to storage.toshiba.com and there are drives but I didn't see anything about this model. I tried Google searching "Toshiba HDKPC08" but that didn't bring up any manufacturers web site info. Some info on the web says it's basically the same as the Hitachi drive.

 

So, would you buy them?

 

FYI, NCIX is also selling Toshiba 2T for $89 and 1T for $60.

 

Edit - doing more reading, it seems for WD to buy Hitachi they had to sell the 3.5 drive business to Toshiba. So these are basically Hitachi 3T drives. Maybe I'll have to pick a couple up.

They are just mislabelled on the ncix website. The model on them is actually DT01ACA300. I bought three of them myself. I'll report back on their performance when I get them precleared.

I think from memory that the Toshiba's are hitachi drives. My memory isn't that great but I think I read somewhere that WD had to get rid part of the drive business when it bough hitachi and sold that part to toshiba.

Hitachi had 3 year warrantee, and Toshiba only 1 year locally here in Europe

 

[bonzi]

Yeah the drives I got show up as Hitachi Deskstar 7K3000 HDS723030. Also says Hitachi on the label in addition to Toshiba.

[lionelhutz]

I'll be seeing them soon. I ordered 3 of them, should show up this week.

[downloadski]

I now see them advertised with 3 years warrantee, i asked the company that offers them if this is correct.

The prices are going down here for this drive, 127,50 euro (excluding shipping)

Bought 3 of these as well. 2 of them are already working in the backup server. So far so good.

Warranty check on mine was until Sept 2014 so barely even 2 years....

 

I doubt you'll get 3 years if you purchase them.

So for those of you that already have these drives how are the temps when they are spun up? I'm debating getting 9 of these right now or waiting a few weeks/months till the ABA 5900 rpm versions are released.

 

Will be running the drives in 3in3 hotswap modules so they won't be too tightly packed.

Mine are in 4in3 hotswap bays and they run 2-3 degrees hotter than the WD green drives.

[Talos]

Thanks for that Lionel. Those temps are pretty good for 7200rpm vs 5200 rpm drives. Think I will just go with 9 of the ACA drives then.

That is what the company claims, i asked it via email, and they confirmed.

They sell for 143 euro, including shipping.

Cheapest seller is 127,40 withouth shipping.

 

For one disk the difference is 10,65 euro.

 

 

I bought 4tb hittchi from them, and they shipped in retail boxes, while other companys shipped in bulk package. Perhaps the warrantee differs between retail and bulk ?

 

Can you tell me what the initial speeds with preclear were ?

I have some old b series hitatchi 1 tb in my server which are slow, and i might replace them with these. Or perhaps other transfer results to these drives if you have any.

Here's the times and speeds from the reports.

 

== Using :Read block size = 8225280 Bytes

== Last Cycle's Pre Read Time  : 6:42:16 (124 MB/s)

== Last Cycle's Zeroing time  : 5:43:35 (145 MB/s)

== Last Cycle's Post Read Time : 15:50:10 (52 MB/s)

== Last Cycle's Post Read Time : 15:52:29 (52 MB/s)

== Last Cycle's Total Time    : 30:32:09

 

This one was precleared on a slower PCIe x1 add-in card.

== Last Cycle's Post Read Time : 20:05:44 (41 MB/s)

== Last Cycle's Total Time    : 34:10:27

 

Compare to say a WD15EARX

 

== Using :Read block size = 8225280 Bytes

== Last Cycle's Post Read Time : 12:37:16 (33 MB/s)

== Last Cycle's Total Time    : 25:17:10

 

Or a WD15EADS

 

== Using :Read block size = 8225280 Bytes

== Last Cycle's Pre Read Time  : 5:46:41 (72 MB/s)

== Last Cycle's Zeroing time  : 5:04:02 (82 MB/s)

== Last Cycle's Post Read Time : 11:06:47 (37 MB/s)

== Last Cycle's Total Time    : 21:58:37

 

Which sadly was faster than the newer EARX which replaced it. The EADS had randomly appearing and dissapearing bad blocks.

 

Or a Hitachi HDS5C3020ALA632 = 5K3000 2T drive.

thanks.. will order one to test and replace a slowing down old 1 TB

These are the disc temps in my server, well into a parity check:

 

Seagate 3TB ST3000DM001 31°C

Seagate 2TB ST2000DL003 28°C

Hitachi 3TB HDS723030BLE640 30°C

WDC 1.5TB WD15EARS 28°C

WDC 2TB WD20EARX 28°C

WDC 1.5TB WD15EARS 29°C

Hitachi 2TB HDS722020ALA330 32°C

WDC 1.5 TB WD15EADS 29°C

Hitachi 3TB HDS723030BLE640 30°C

WDC 2TB WD20EARS 27°C

Hitachi 3TB HDS723030BLE640 29°C

Seagate 2TB ST32000542AS 27°C

 

The Toshiba (Hitachi) 3TB seems to be running 1 to 3°C hotter than the coldest "green" drives, also a couple of degrees colder than my Hitachi 2TB (HDS722020ALA330).

[UhClem]

I'm curious about these new Toshachi 3TB drives. For those who have them, could you run the following command on each of them and report the results (nnn MB/sec):

hdparm -t /dev/sdX

(replace sdX as appropriate)

 

And, for luca, could you do the same command on your Seagate 3TB (ST3000DM001) and the (older) Hitachi 2TB (HDS72020ALA330).

 

Thanks.

The Toshiba 3TB does appear to be a noticeable update of the Hitachi 7K3000 3TB (HDS723030ALA640) [which would typically measure ~155].

 

Note that the hdparm (-t) measurement only looks at a very narrow portion of the drive, and is not appropriate for any decision making.

 

For example, your Seagate 3TB measurement seems somewhat low; I would have expected 170-175. But do not worry; if hdparm allowed a user-specified offest for the -t test, you could verify this variance. You can use the dd command if you wanted, e.g.,

dd if=/dev/sdX of=/dev/null bs=1M count=256 skip=5K

will time 256 MB of reading (256 * 1M) starting at an offset of 5GB (5K * 1M). By varying that 5K parameter, you can witness the variance, even within the "outer" (ie, fastest) cylinder range. Note that dd reports MB/sec whereas hdparm reports MiB/sec.
