Fixstars unveiled the world's highest capacity SSD in the 2.5-inch form-factor, with a SATA 6 Gb/s interface, the Fixstars SSD-6000M. This drive offers 6,000 GB of unformatted space, and uses 15 nm MLC NAND flash chips. The underlying controller is unknown, but the drive offers reasonably high sequential transfer speeds of up to 540 MB/s read, with up to 520 MB/s writes. The drive supports modern SSD features, such as NCQ, TRIM, and SMART. The drive is 9.5 mm thick, and may not fit in certain kinds of notebooks. The company plans to launch the drive some time in July, 2015, backed by a 3-year warranty.
