How large are the sustained writes that you are using to quantify the disk's speed in the sustained rate categories?
I developed a logging application that creates files of 250GB+, using a Black carviar drive, and it seems that the sustained rate of the drive is closer to 20-30 MB/s. I am getting buffer overflows logging data at a constant data rate of 27 MB/s... This is with overlapped IO with absolutely no data processing, preallocation of the file size, and windows file buffering turned off.
