I run a 2.1.5 system with the 2940UW card and a few Seagate Elite drives.
I've been quite happy with the performance. Here are some iozone
measurements I took:
Writing the 64 Megabyte file, 'iozone.tmp'...33.671875 seconds
Reading the file...20.984375 seconds
IOZONE performance measurements:
1993024 bytes/second for writing the file
3198039 bytes/second for reading the file
The Elites are fast/narrow drives, I don't have any fast/wides or ultras.
That considered, I'm pretty pleased with these numbers. On the same logic
board I get about 2100k/sec from reasonably good IDE drives.
