Super Talent's RAIDDrive II Plus seems to know only one trick

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."

Why in the heck would they USB 3.0 connect the SSD to the board? Are you sure that is correct? That would completely blow away any reason to use a PCIe interface card. Yeah I can't see any reason to purchase something like this.

In reply to my own post, if you read the other article, its not actually USB.. Its SATA over a USB connector.
