I use the BP6 with FreeBSD-current and Slackware. The Highpoint works
great with FreeBSD however I have a problem with the Maxtor running fsck
under Linux. This has occurred since the beginning of support for the
Highpoint. I have used Hedricks patches and nagged him about problems
but the only remaining issue is fsck. It works perfectly with the PIIX
controller. Benchmarks sizzle with the Maxtor/Highpoint almost 24MB/sec
so the tradeoff is acceptable(to me). The best the IBM could muster was
20MB/sec. The Maxtor/PIIX runs a little over 19MB/sec occasionally
hitting 20MB/sec.
