It is only worth it if you are willing to drop the fu$$ies to do it right! I have a hardware card from Adaptec and a 5-disk Intel hot-swap SCSI cage in my PC. OK, so I am a bit extreme... but... Motherboard RAID? Can't be trusted, in my opinion. Better than nothing, but... In the case of my RAID 5 of 320 SCSIs, it works well. Much less wait for Windows Explorer or the like when I am in a multitasking frenzy! Data seems to move a LOT faster that single drive. I have not benchmarked with RAID 0/1/5 or anything, but just know that if you drop the cash, at least one guy is happy with the results! kc
