Toshiba today announced three new families of solid state drives (SSDs) fitted with high-speed PCIe interfaces. The drives use the NVMe protocol and all three SSD families make use of Toshiba-developed controller platforms and Toshiba’s own MLC NAND flash memory.
The XG3 family of SSDs is housed in M.2 Type 2280 form factor and targeted at notebooks and PCs and available up to 1 TB. The drives support up to four lanes of PCIe 3.1, which has a maximum interface bandwidth more than six times that of SATA 6.0 Gbits/s. Toshiba claims the XG3 is the industry’s first NVMe SSD available in a 2.5-inch SATA express form factor. The SSD family is equipped with Toshiba’s QSBC (Quadruple Swing-By Code) error-correction technology and also features lower power state modes. It is the first Toshiba product, along with the BG1 SSD family, to support the Trusted Computing Group security specification, Pyrite (TCG Pyrite).
The BG1 SSD family is the world’s smallest NVMe SSD, according to Toshiba. It is targeted at thin notebooks and tablets and available in a single package measuring just 16mm x 20mm (M.2 Type 1620) or a removable M.2 Type 2230 module with up to 256GB in capacity. The BG1 SSD family supports TCG Pyrite and features lower power state modes.
The PX04P series of enterprise SSDs are designed for servers and storage appliances needing scalable power and performance settings. Toshiba claims the PX04P series NVMe SSD has the industry’s lowest power consumption, with only 18 Watts needed to power the drive at maximum performance. The PX04P family also supports up to four lanes of PCIe 3.0, and is available in either a HHHL (half-height half-length) add-in card or a 2.5-inch form factor with SFF-8639 connector. The eSSD family is also equipped with Toshiba’s QSBC error-correction technology.
Samples of Toshiba’s newest lines of NVMe PCIe SSDs will be available in Q4 2015.
