johnnyMon Posted March 20, 2006 Posted March 20, 2006 Actually, those numbers look about right. You're only off the theoretical by about 10% so you should feel good about it....Start saving your lunch money now so you can get the second drive by the time you need to do a clean install.

Redbeaver Posted March 22, 2006 Posted March 22, 2006 Actually, those numbers look about right. You're only off the theoretical by about 10% so you should feel good about it. It's the same with a RAID-0 array. You don't get exactly twice the performance because you have two drives. Start saving your lunch money now so you can get the second drive by the time you need to do a clean install. but dude, isnt the new Raptor150s SATA2? my WD250Gb SATA2 is posting a burst around 175Mb/s...... and his average are in the 70's MB/s. My average is about 90Mb/s. how could a fat single-drive WD2500KS 250Gb SATAII/3.0 w/ 16mb cache beat the crap of the brand-new Raptors150 wit 10,000rpm???

johnnyMon Posted March 22, 2006 Posted March 22, 2006 ^ Maybe I should install the Nvidia IDE SW driver? Gurus here say not to install it if I'm not running RAID, but maybe it will make a difference. Right now I'm pretty sure Windows sees my Raptor as an IDE drive. I would need to image my hard drive first in case it messes something up. I've read a few horror stories about this driver, but that was a little while ago. Share this post Link to post Share on other sites More sharing options...
soundx98 Posted March 22, 2006 Posted March 22, 2006 Raptor 150's are SATA 1. WD said they were shipping that way for "system compatability". Scuttlebutt is that they will have a SATA 2 enabler program in the future. Share this post Link to post Share on other sites More sharing options...
Redbeaver Posted March 24, 2006 Posted March 24, 2006 ic. but even my older 160Gb WD SATA1 can reach about 135Mb/s burst and 95mb/s average. how come 10,000rpm doesnt help at all? Share this post Link to post Share on other sites More sharing options...
blinker0 Posted March 25, 2006 Posted March 25, 2006 See if anyone can figure out whats going wrong here three 74G Raptors [/img] Whats wrong with this picture?

I aint got much hair left after all the head scrartching trying to figure this one out Share this post Link to post Share on other sites More sharing options...
SoyoJoe Posted March 25, 2006 Posted March 25, 2006 Probably your cluster size, i would have used a 16k stripe and a 4k cluster. Share this post Link to post Share on other sites More sharing options...
blinker0 Posted March 25, 2006 Posted March 25, 2006 Probably your cluster size, i would have used a 16k stripe and a 4k cluster. Already tried that.. I/O meter And ATTO. Both show a improvement when the third drive is added.. Only HD TACH Shows that it is actualy slower Share this post Link to post Share on other sites More sharing options...

blinker0 Posted March 25, 2006 Posted March 25, 2006 Put it into 2 equal partitions, Disabled read caching and Command queing. edited last post to show stripe and cluster size Share this post Link to post Share on other sites More sharing options...
Tecklord Posted March 26, 2006 Posted March 26, 2006 Put it into 2 equal partitions, Disabled read caching and Command queing. edited last post to show stripe and cluster size I can disable command queing but where do you disable read cache?
