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

went fairly quickly.

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