Solid-state drives with NVMe & PCIe protocol/interfaces

August 12, 2015 // By Graham Prophet
With low latency and power efficiency, Toshiba Electronics Europe has added three families of solid state drives (SSDs) fitted with high-speed PCIe interfaces that provide high-bandwidth point-to-point links with the processor and reduce system bottlenecks. The drives use the NVMe (Non-Volatile Memory Express) protocol.

All three SSD families make use of Toshiba-developed controller platforms and Toshiba’s own state-of-the-art MLC NAND flash memory. For high performance notebooks and PCs, the XG3 family of SSDs is housed in M.2 Type 2280 form factor and is the highest-available capacity (1024 GB) client NVMe SSD designed for high performance notebooks, 2-in-1 laptop and all-in-one PCs.

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/sec. The XG3 is also the first NVMe SSD available in a 2.5-inch SATA express form factor. The XG3 SSD family is equipped with Toshiba’s QSBC (Quadruple Swing-By Code) error-correction technology, a highly efficient error correction code (ECC), which helps protect data from corruption, improves reliability, and extends the life of Toshiba SSDs. Engineered for power efficiency, the XG3 series also features lower power state modes and is the first Toshiba product, along with the BG1 SSD family, to support the Trusted Computing Group security specification, Pyrite (TCG Pyrite).

For thin notebooks and tablets, the BG1 SSD family is the smallest NVMe SSD, available in a single package measuring 16 x 20 mm (M.2 Type 1620) or a removable M.2 Type 2230 module with up to 256 GB capacity. Designed for thin notebooks, 2-in-1/convertible notebooks and tablets, the BG1 family enables PC OEMs to produce thin mobile PCs and tablets while offering a better performing alternative over SATA SSDs for mobile PCs. The BG1 SSD family supports TCG Pyrite and features lower power state modes.

For servers and storage appliances, the PX04P series of enterprise SSDs is designed for servers and storage appliances needing scalable power and performance settings. The PX04P series NVMe SSD has the lowest-available power consumption, with only 18W 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
