[Techpowerup.com] A-Data Cashes in on Smart Response and Embedded Markets with New mSATA SSDs
Intel's Smart Response technology is doing wonders to the low-cost SSD market. The technology lets low-capacity, usually low-cost SSDs to be used as caches for hard drives, improving the system's overall responsiveness. The technology makes these low-cost SSDs more of a component than a product (such as 2.5-inch SATA SSDs), and hence it makes sense to offer them in the mSATA form-factor. Intel made its headstart by launching the Intel 311 "Larson Creek" series 20 GB SSD that comes in both 2.5-inch SATA 3 Gb/s and mSATA form factors. While mSATA makes it easy to deploy the technology into notebooks, desktop motherboard vendors such as Gigabyte thought it would be nice to give their motherboards an mSATA slot.
Capitalizing on this very market is A-Data, with a couple of new low-cost mSATA SSDs in the ISFM series. First is the ISFM-XM13, an mSATA SSD driven by a SandForce SF-1200 series controller. Even with some of the controller's channels unoccupied (due to obvious lack of space to put NAND flash chips), this card doles out decent transfer rates of up to 250 MB/s read and 170 MB/s write. This card comes in capacities of 30 GB (32 GB with 2 GB overprovisioned) and 60 GB (64 GB with 4 GB overprovisioned). This card uses MLC NAND flash. Next up, is the ISFM-IXM01, that looks to be using a JMicron-made controller. The bigger difference here is the use of SLC NAND flash on one of its two variants, which traditionally offers higher rewrite cycles. The other variant uses MLC NAND flash. The SLC variant offers transfer rates of 90 MB/s read and 90 MB/s write, and comes in capacities of 2, 4, 8, and 16 GB. The MLC variant gives you 150 MB/s read, 120 MB/s write; and comes in capacities of 32, 64, and 128 GB.
