I needed more sata ports, and my motherboard only had 3. This allowed me to add 4 more ports, and thus 4 more hard drives. The card was recognized by windows 10, so I had no driver issues. The card worked so great that I ended up buying another card.
Relatively easy installation, I am able to run this card either from my UEFI/BIOS or GUI on the desktop, though I need to remember the command to do it for the latter.
-Recognized directly with Truenas -Well packaged in a plastic case to protect the card in shipping.
-Cheap -Compatible with TrueNAS -Fast Transfering over single 10Gb from Windows -> TrueNAS RAID10 -> RAIDZ @ [~700-980 MB/s]
*12Gb SAS -- Insanely fast (was able to read ~7300 MB/s from a large SSD stripe V-Dev) *LSI so you know it runs flawlessly out of the box on Linux *It's not a RAID card, just a pure host bus adapter that doesn't get in the way *Absolutely perfect HBA for a ZFSonLinux box (probably works well on *BSD too) *Supports 24 direct connections to drives or passive/direct backplane, or up to 1024 drives through expanders
Reversible connectors (you can switch internal to external via jumpers), small footprint for tight cases
