Toshiba places 1TB on m2 SSD of 22x30mm

Toshiba has unveiled its BG4 line of SSDs. The manufacturer provides the SSDs with a single package with 3D Nand memory in 96 layers, with capacities up to 1TB. The storage will be on the market in 1620 and 2230 m2 form factors.

With the compact BG4 SSDs, Toshiba focuses on applications such as thin notebooks and embedded systems for the Internet of Things. The pci-e 3.0 x4 flash disks read sequentially at 2250MB/s, significantly more than the 1520MB/s of the BG3 generation that Toshiba announced two years ago. The writing performance itself would be 90 percent higher and the energy efficiency during reading and writing has also been improved by 20 and 7 percent respectively, the manufacturer claims.

The BG4 will be available in 128, 256, 512 and 1024GB capacities. Toshiba is releasing the memory in bga variants with an m2 1620 form factor of 16x20mm and as removable m2 2230 modules of 22x30mm. The manufacturer is making the first copies available to PC builders in limited quantities. Broad availability should follow in the second quarter of this year.
