Toshiba launched three new series of SSDs based on the new PCIe and NVMe protocols. The products span everything from traditional notebooks to high performance PCs to datacenter SSD offerings. Each series is manufactured with a Toshiba developed controller and NAND. We use PX02 and PX03 SAS3 SSDs as well as some lower cost 480GB Toshiba SATA SSDs in the datacenter and all have performed well for us. It is exciting to see Toshiba come out with new offerings especially the PX04 series.
Here are the descriptions from the press release:
Toshiba 2015 NVMe SSD Lineup
HIGH PERFORMANCE NOTEBOOKS AND PCs: The XG3 family of SSDs is the industry’s highest capacity[3] (1024GB[4]) client NVMe SSD available in M.2 Type 2280 form factor and optimally designed for high performance notebooks, 2-in-1 PCs and all-in-one PCs. The XG3 in M.2 Type 2280 form factor supports up to four lanes of PCIe 3.1, which has a maximum interface bandwidth more than six times that of SATA 6Gbits/s[5]. The XG3 is also the industry’s first NVMe SSD available in 2.5-inch SATA express form factor. The XG3 SSD family is equipped with Toshiba’s proprietary Quadruple Swing-By Code (QSBC®[6]) error-correction technology, a highly efficient error correction code (ECC), which helps protect customer 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 specification, Pyrite (TCG Pyrite).
THIN NOTEBOOKS AND TABLETS: The BG1 SSD family is the world’s smallest NVMe SSD[7], available in a single 16mm x 20mm package (M.2 Type 1620) or a removable M.2 Type 2230 module with up to 256GB in 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.
SERVERS AND STORAGE APPLIANCES: The PX04P series of enterprise SSDs are designed for servers and storage appliances needing scalable power and performance settings. The PX04P series2.5-inch NVMe SSD has the industry’s lowest power consumption[8]. With only 18 watts active power driving maximum performance, the PX04P’s combined power plus performance bring low TCO demanded by today’s enterprise data centers. The PX04P series also supports up to four lanes of PCIe 3.0, and is available in either a half-height half-length (HHHL) add-in card or a 2.5-inch form factor with SFF-8639 connector. The PX04P series eSDDs are also equipped with Toshiba’s QSBC® error-correction technology.
