Hmm, I still think that SCSI would be best in highdemand situations, however it should be possible with some pretty good figures using EIDE/ATA drives. And no our current ide (more wdc) driver has no support for this, that situation could change though given the right circumstances..... -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Soren Schmidt (sos@FreeBSD.org) FreeBSD Core Team So much code to hack -- so little time.
