I'm trying to figure out if I need a separate RAID card or if I can get the embedded one (S2600CP2 motherboard) to work fast and reliably. Without write caching (WC) enabled on a VD I'm not going to get enough performance and WC of course is not fault tolerant without a BBU or equivalent. If I upgrade (with the C600 RAID key) and enable SSD Caching, does this provide the equivalent performance to WC while at the same time providing increased fault tolerance?
In other words, does SSD Caching on a RAID1 array speed up performance while having some benefit to data protection in the case of an unexpected power loss, i.e. will I get the performance and data protection somewhat equivalent to one of the cards with included Flash and BBU (e.g. RS2VB080)?
Also, would I enable WC now on an array with SSD Caching, or never use WC?
Thanks,
Nick.
