Unified Serial RAID Controllers for PCIe

Benchmark Results

RAID Initialization Time

We used eight Seagate Savvio 10K.2 hard drives to determine the time needed by the controllers to create a RAID 5 or RAID 6 array.

Clearly, the cards with the faster XOR accelerators complete the array creation task quickest. However, all products support background initialization, which reduces available performance but lets you start using the array right away.
