Bonnie++ on the Mylex cards I tested with a few years ago gave quite poor
results. The performance of reading and writing large files sequentially on
an array of U160 disks was significantly less than on a single cheap IDE
disk.
The seek times were quite good however, so doing an upgrade through dselect
went fairly quickly.

This is annoying. But they aren't alone, there's CCISS and IDA as well.
