Don't need hardware RAID? Want to access your drives as individual volumes without dealing with management interfaces? Or using a non-hard drive SAS device such as a tape drive? Then a 12Gb/s or 6Gb/s host bus adapter is what you need. They are also great for DAS units with on-board RAID controllers, and provide better performance than port multiplier units if multiple drives are accessed at the same time. Most of them also support SAS expanders. Couple these HBAs with our SAS / SATA enclosures for a complete JBOD system.
Broadcom SAS HBAs are the most popular and they have drivers for just about every OS on the PC. If you need a card for your Mac Pro, Areca SAS HBAs would be your solution.
