Hello folks,

Pardon me with this newbie hardware question. I have an

ASRock 939SLI32-eSATA2: ULi Dual x16 SLI motherboard

http://www.anandtech.com/mb/showdoc.aspx?i=2706


I just bought a
Seagate 160GB Hard Drive
7200RPM, Internal, SATA/300, 3.5 inch, 8MB hard drive.

I have a
Hitachi Deskstar 7K250 160GB Hard Drive
7200RPM, Internal, ATA/100

http://www.compusa.com/products/pro...ode=314482&Pn=Deskstar_7K250_160GB_Hard_Drive

I just did a speed comparison with:
Drive Speed Checker

http://www.benchmarkhq.ru/english.html?/be_hdd.html


The segate scored 55,159 write and 38,647 read.

The hitachi scored 32,407 write and 38,395 read.

I'm dissapointed. I thought the segate sata III drive would kick super steak bombs on both read and write tests against the hitatchi ata 100 drive.

Can you folks explain if/why the read speed is so slow when compared to the hitatch? I really hoping that I would get faster read speeds with the segate sata III. I bought the new drive to load my games faster (doom, farcry, soldiers heroes of WWII).

How do I know if this drive is running at sata III speeds? Is there another test I can do to show whether I am really getting more performance out of a Sata III drive?

Thank you in advance for your information. :)
 
You might want to try more than one benchmark to get a better idea, like SiSoft Sandra.

If the Seagate drive is running with NCQ enabled, write performance may be diminished, so you could potentially disable that. Also, check the jumpers on the Seagate to make sure its set for SATA300 and not 150 (sometimes its set for 150 from the factory for compatability reasons).

The limit of the transfer rate to the platters is Still ATA133. (Hence why a lot of people did not buy into the Sata300 thing)
While there MAY be a performance boost to running sata2, on my motherboards it did not make a difference. But it should if you stripe a couple :)

(your MB does not have the sata2 port running through the IDE bus, so thats why I said it may improve it.)

The reason the Seagate scores higher on Write is because of the HDD cache, disk writes are slower.

The read speed has nothing to do with cache, thats why its similar on both.
