What filesystem should I use?

ext3:
I use this on all our boxes now. Occasionally, something winds up in lost+found, but the benefit of 5-second reboots rather than 5-minute reboots is phenomenal.

Reiserfs:
also journals, but it's recovery from power-fail may be less robust

How about DMA?

Switching on DMA modes for HDD increased the latencies on my system a lot. So I switched them off. Of course now HDD access is much slower, but since a real-time system normally is not used as a file server this drawback is not very important.

Wonder about SCSI?
