LSI HBAs are acknowledged as the most Linux compatible/friendly and
highest performance HBAs/RAID cards available. The 9211-4i is the least
expensive HBA in their lineup, a PCIe 2.0 x4 card w/4 ports. It is
capable of full 4GB/s PCIe 2.0 x4 duplex throughput with sufficient
drives/SSDs attached, much higher performance than Intel Southbridge
SATA controllers.
It does also offer hardware RAID 0/1/1E/10 if you choose to use it.
This is not fakeraid but the same firmware RAID on LSI's RAID cards.
You can boot the OS directly from an array as with any RAID card.
However due to lack of write cache DRAM it is much slower than their
full up RAID cards, but on par with the performance of Linux md RAID
0/1/10 at low spinning drive counts (2-8). The RAID function is not
suitable for use with SSDs as the ASIC is simply too slow for the high
IO rates.

$192, $48/port, w/breakout cable for 4 drives.
Ya can't go wrong with LSI.
