The Super Talent RAIDDrive II Plus is a rather interesting take on a PCIe SSD card, it's USB 3.0 connected 25nm MLC NAND storage is on one PCB with a SF-2281 to handle the traffic and on the second PCB is an LSI 2108 RAID on a Chip and 1GB of DDR2-800.  That LSI RoC can support most RAID modes, giving you either higher performance or increased reliability all on a single PCIe SSD card.  For testing purposes The SSD Review used RAID 0 and found that except in one certain scenario the card was outclassed by a single Intel 480 SSD.  If you are not scared of a tough price of $4/GB on a 2TB device and need fast large block sequential reads and writes with no expectation of quick random reads nor writes this is a good choice.  Otherwise you might want to consider other alternatives but the technology on this device is rather intriguing.

"The second type of PCIe add-in-card storage takes more of a brute force approach. These devices typically have off-the-shelf SATA/SAS controllers and connect via a PCIe bridge. Think of a HBA/RAID card connected to a SATA SSD, but on a single card. These designs have many advantages and disadvantages. While the cost and time-to-market can be low, they are inherently limited due to the architecture."
