Thread: RAID motherboard against low-cost controller

There is a motherboard with two embedded controllers:
SATA: NVIDIA CK8-04 Pro, 4 Ports
Silicon Image SiI3114, 4 Ports

Will differ if the performance and reliability if you like to hang across this array controller Promise FastTrak TX4650. And what advantages do I have low-cost controllers over a 2-name above, embedded in a motherboard.

There will be faster than the Silicon Image. The main advantage of this controller to another - it is "little blood" using SAS-disks, and this is a very drastic increase in speed server applications. Unfortunately, these controllers (Promise TX2650/TX4650) sufficiently large amount of criticism for stability, so it's responsible for their applications, we recommend not venture.
