Pros: None really other than it appears to work with 6 drives. Software drivers not easily found and installed. Also, complicated manual and many modes and firmware options.

Cons: Performance sucks! I purchased the card for its 6Gbps interfaces. However, in Raid 10 mode, the read performance is 250MBps, instead of 1GBps. I did not realize that this is not a real RAID card, allowing double performance associated with striping. The card is deceptively advertised, listed under Raid cards. Apparently RAID 10 reduced overall performance.

Overall Review: Don't buy for performance, only data security (if that)
