Toshiba 7200rpm 4 gig, about 200 MB/sec

What's your testing methodology? You could be seeing page caching from the OS.
I'm puzzled how a tiny 4GB drive can make those numbers.

Not really a
I think he probably meant the terrible bytes. :rotfl:

I think the free version of HD tune only tests to 2TB.

Wotty wot wot.
We use some of the 2TB Toshiba's (DT01ACA200) at work, and we also see ~170-180MB/s sustained off them. (Reads 170-180MB/s, writes 160-170MB/s, with both slowing as we get towards the end of the platter)...
Block size = 64K, queue depth approx ~128 (avgrq-sz), file size is 500GB-1TB+. (OS = Ubuntu 14.04.3LTS).
eg (iostat output).

Chewy509
Wotty wot wot.
During write, it's our own forensic acquisition software generating the load (so is dependent on the source device and contents as well), but when the source is an SSD, the SSDs read performance easily outstrips the write performance of the Toshiba... All our software uses O_DIRECT for cache bypass hinting for both read and write, not that it really matters when you're transferring TB's at a time...
But here is the iostat output when # dd if=/dev/zero of=/dev/sdf bs=1M

Have the 3.5" drives developed any interesting technology improvements since being split off from Hitachi?

Solid... Fast... Grande storage...
By Richard Brookes on July 31, 2013
Size: 3 TB Verified Purchase
After a lot of review reading and research into larger capacity hard drives, I settled on this Toshiba because of the size to price ratio,low power consumption, and the 7200rpm spindle speed.
There seems to be a huge reliability problem with large 1TB plus drives on the market, I had a very hard time finding consistent good reviews on ANY manufacturer. I was seriously considering a Western Digital "Green" drive, to use in my Home Theater PC, but this was going to serve as my main operating system drive as well as storage, the slowish speeds concerned me. I found this Toshiba (yes it is a re-branded Hitachi) on sale, and most of the reviews seemed favorable, so I bought it.
I've had it for about 4 months, and it is getting close to full already, let me say this; the drive is fast, seemingly reliable, and I'm very happy with it. I got the retail box for the manufacturer's warranty, to be safe, but seems like a terrific drive. My system boots fast, has no problem reading and playing high def video, and it is QUIET, and according to the specs (I have no real way to test this) power friendly, which is what I need for a Home Theater machine.
Highly recommended product.
Thank you for reading my review.
