No, both the SX4000 and SX6000 RAID controllers have hardware-based XOR calculations. As such, they would (in theory) have better performance for RAID5. They can also use large SDRAM caches. The FastTrak TX2000 controllers use BIOS mappings to do mirroring / striping / JBOD. You really are better off using software-based RAID instead. The only time to use these is with an OS that doesn't natively support RAID, such as WinXP Home or Win95. Promise has a poor record of Linux support, in my experience. You're much better off using a 3ware product for hardware-based IDE RAID. -B -- Brandon High [EMAIL PROTECTED] Epinions, Inc.
