Hello, Hier is a problem that we have with a FreeBSD 4.3-REALEASE and I think that it is more a bug that a problem. We wanted to run a system with installed 3 Promise FastTrack ATA/100 controllers with 10 70GB IDE Hard Drives. Internal IDE controllers were turned off and a SCSI Hard Drive was used as booting device. On 4.2-RELEASE using vinom we managed to run RAID-10 (or what vinom calles RAID-10) and we had perfomance of 30 MB/sec sequential writing to this ata harddrives. But the 4.2 system was unstable and crushed 3 times in 2 days during the havy load. On 4.3 system it seems to be more stable (but we did run it only several hours) and the performance was horrible: about 8 MB/sec for writing.
