I can only speak for a 9690SA-8I, but this thing is amazing. It handles FSs over 2TB pretty well: twa0: <3ware 9000 series Storage Controller> port 0xc800-0xc8ff mem 0xfa000000-0xfbffffff,0xfeaff000-0xfeafffff irq 16 at device 0.0 on pci4 twa0: [ITHREAD] twa0: INFO: (0x15: 0x1300): Controller details:: Model 9690SA-8I, 128 ports, Firmware FH9X 4.10.00.007, BIOS BE9X 4.08.00.002 And with 8 1TB in a RAID5 drives it gives me: da0 at twa0 bus 0 target 0 lun 0 box:~>diskinfo /dev/da0 /dev/da0 512 6999924277248 13671727104 851025 255 63 -Andre > > We are going to use FreeBSD 8.0 and Bacula, but first we obviously need to > create a working RAID. > > My questions are: > > - Are HighPoint RocketRaid controllers a good alternative to 3ware > controllers?
