NVM Express solid-state drives are the future, and Toshiba is bringing that future a little closer today with the release of three NVMe PCIe SSD families. These product lines are targeted at "high-performance notebooks and PCs, thin notebooks and tablets, and servers and storage appliances."
The XG3 series of drives may be most interesting for the PC enthusiast: they're the ones meant for "high-performance notebooks and PCs." Toshiba says that XG3 drives will be available in an M.2 2280 (or gumstick) package, as well as a 2.5" SATA Express form factor. No matter which flavor you choose, XG3 drives will be available in capacities up to 1TB, and they can connect to as many as four PCIe 3.1 lanes. They also offer support for the Trusted Computing Group's Pyrite storage security specification. We've contacted Toshiba to see if we can get some performance figures for these puppies.
On the business computing front, the PX04P series of drives offers NVMe performance with low power consumption. Toshiba claims these drives can run at full tilt while sipping 18W of juice, which could mollify those who need to worry about energy costs at data-center scale.
Finally, the BG1 series puts up to 256GB of NVMe storage on a (presumably soldered) 16-mm by 20-mm package, or a removable M.2 2230 module. These drives are supposed to offer better performance than SATA drives in thin tablet PCs and convertible notebooks. They offer TCG Pyrite support, as well.
Toshiba says it'll begin sampling these new NVMe drives in Q4 of this year.
