Re: RAID 0 on Promise Fasttrack Speed P4C800-E Deluxe

I could have sworn that early on in your post you stated, correctly, that
your motherboard does NOT support SATA II. Sooo, why would you expect to
get 300MB/s for a transfer rate using an SATA II harddrive?
P.S. Even if your board did support SATA II you need to know that the 300
MB\s transfer rate that you mentioned is a theoretical maximum and is
actually unobtainable in the real world.

Alright, I just bought 2 new 320gig western digital 16mb cache, SATA II
(300 MB/s) drives. I have a P4C800-E Deluxe which I know only supports
SATA I. I set up a RAID 0 array last night, installed a fresh copy of
Windows Vista Beta 2, and have been running tests with HD tach 3.0. My
burst speed for the drives is only about 107 MB/s where my ATA133
Maxtor gets about 115 MB/s. The average read speed for the RAID array
is double what the Maxtor is, about 80 MB/s, but I still expected the
RAID to have much higher burst speed. In theory it should be 300 MB/s
but I'm not even getting the burst speed of a single ATA133 drive which
is upsetting. I just flashed my BIOS and disabled legacy USB support
because I read that might help. I have ran the test a bunch of time.
The promise drivers are the latest ones. Any help?
