As opposed to the slowly developing HDD market (our recent roundup covered the entire year), solid state drives are evolving at a much more rapid rate and bringing us more news in a shorter period. There are SSD products with new controllers, with PCI Express interface, with new firmware, etc. We, at X-bit labs, have to be running fast just to stay where we are and keep you in touch with the latest market developments.So in this review we are going to take a look at an SSD designed as a PCIe controller and check out if it is better than a RAID array built out of two ordinary 2.5-inch SSDs. We will also benchmark low-capacity SSDs based on the SandForce controller.
