but how it performs on raid 0 array??To enhance the write performance of RAID 5, Intel® Matrix Storage Manager software has implemented a RAID 5 volume write-back cache and coalescer. The volume write-back cache allows writes to be buffered and improves coalescing. The cache is disabled by default, but can be enabled by the user through the Intel® Matrix Storage Console. An Uninterrupted Power Supply (UPS) is recommended for use if the cache is enabled.

it seems that there's an improvement over the default setting. some reports stated that different vendor may produce different performance results with the volume write-back cache enabled. just make sure you have an uninterrupted power supply (UPS) in order to avoid the things we do not want when this feature enabled.
