Pros: Works with Server 2008, 2008 R2 and 2012! Does not conflict with onboard RAID or SATA.

Cons: Software only RAID, so it's limited to RAID levels 0/1/5. PCI-X

Overall Review: I was having a tough time trying to get an Adaptec or LSI PCI-e RAID adapters to work on my new 2012 build. Both cards were a few years old, but I wanted H/W RAID and onboard memory. Neither of these cards played well with my onboard SATA. After 2 days of mucking around, I remembered I had this old card in inventory. Plugged it in and BAM! (after I loaded the Sonnet Tempo SATA Gen2 PCI-X adapter driver). Performance isn't as good as a full H/W RAID solution, but I was able to get the capacity I was looking for.
