Clevo D900T slow drives?

I have mobo revision 6.3 and 2 sata 300 drives in a RAID0, you would expect to see really fast performance, but no. I just ran HD Tach and my performance is about 20% less then Sata 150. I just defraged and I keep my drives in great shape. Is there a setting in Bios that I can change to make them Sata 300 speeds? I do notice that every time I boot, it says Scanning IDE Drives but I never really took it into consideration. Btw, my scores were 80mb/s sequncial read, 106.7mb/s burst speed and random access time of 16.1ms. These are the drives I'm using http://www.newegg.com/Product/Product.aspx?Item=N82E16822116039

 

don't confuse the sata-rating with real harddrive performance. the rating just gives the max theoretical throughput of the sata-link between hdd and mobo. the hdd itself is usually much slower.
and given the 80mb/s are the average over the whole disk, this roughly is what you should expect from 2x 80GB 7k2 in RAID 0.
if you want more, get faster(bigger) hdds

 

is this using intel storage matrix? is "write back cache" enabled? HD tach is a tricky beast... did you have any other programs running in the back ground? try booting in safe mode, and re-run the HDtach... looking at the link, dont expect awesome performance from those drives...

 

Thanks for the posts, I do believe it is just the drives unless someone that knows alot about the D900T tells me different. can you suggest anything faster, can't afford SSD's yet so don't even consider that an option.

 

Either 2x 320GB 7200rpm, or 2x 500GB 5400rpm would give you the best non SSD performance (in raid-0 of course).

 

for the cost of 2 fast 7200 rpm drives you can get the 128gb kingston v series ssd for 250.00

 

128GB vs 1TB?

Yes you get slightly more speed, but is it enough to justify it?

 

It has been a while, I cant remember if version 6.3 supports SATA 300 drives. I thought all D900T boards under v6.5 used SATA 150, but I could be wrong there.
You arent going to get insane speed when using an SSD. I had an 80gb intel x-25M in my D900K, and it capped at 120mb/sec continuous. It wouldnt go any higher.
Your drives should be decently fast, yes upgrading them would give you higher performance, but unless you plan on keeping that laptop for a while, I would start saving up for a new one.

Yeah, I plan on keeping the laptop for a while, even replacing the motherboard with a D900K should the need come up. I just did the test because I noticed while playing Left 4 Dead, although I loaded fast, most everyone else loaded faster. Just kind of a nit-picky thing since everything else is really fast, Geforce 7950GTX, P4 3.8ghz cpu, 4Gb's ram, plays Crysis at 24fps and Bioshock at 30fps. Sure, I don't have DX11, an HDMI port, external pci-express 2.0 or a decent battery life, but it does have heart (woot for sappy specs) and it won't be replaced until Fermi equipped laptops come around
