Data storage expert TDK corporation unveiled the eSSD, a single-package embedded SSD chip. The chip combines a SATA 3 Gb/s SSD controller, and NAND flash in capacities ranging between 1 GB to 4 GB. The SSD controller logic is based on TDK's new GBDriver R3 controller design, and the NAND flash is of single-layer cell (SLC) type. The eSSD provides sequential transfer rates of 55 MB/s read, and 30 MB/s write, it packs an automatic garbage disposal and wear-leveling logic, along with native 128-bit AES data encryption. The package measures 17 x 17 mm, with a ball-count of 208. The chip can be part of anything, from large logic boards of embedded computing appliances, to tiny half-height mSATA SSDs. TDK is giving the chip in its mSATA board forms as evaluation samples.
