Other than SAS being the only one to use SAS drives, what is the difference between these two types of raid? If they are both 6Gb/sec, which would be better for SSD's? I am wanting to set up a raid in my Dell Precision T7400 in a PCI express 16X 2.0 slot. I am going to be using eight Samsung 512Gb 840 pro's in two raid 10 configurations of four each. One for each operating systems I plan to run. I have been looking at an LSI MegaRAID SAS 9266-8i for about $550.00 and several SATA III raid controller cards that are much less expensive. Any and all help is greatly appreciated.
