SubjectRe: 3ware 9550SX problems - mke2fs incredibly slow writing last third of inode tables

In my experience, the 3ware SATA controllers which are not NCQ-capable
have very, very lousy write performance with some drives, unless you
enable the write cache (which is, of course, a bit dangerous without
UPS or battery backup on the controller).
