The latest achievement of Toshiba in the field of flash memory was the mass production of the world's most advanced 64-layer 3D NAND TLC (in the definition of the company - BiCS TLC) with a capacity of 512 Gbit. Packing several such crystals in one case allows you to produce a capacitive single-case SSD. In other words, to produce very small in size solid-state drives for compact computing. So, in the new series of budget BG3 SS3, the company introduced a number of models in the form factors
M.2 1620 (pictured left) and M.2 2230 (pictured right).
In the form factor M.2 1620 it's just one chip with a contact group BGA for wiring to the board - models with a capacity of 128 GB and 256 GB have a height of 1.35 mm, and models with a capacity of 512 GB of height 1.5 mm. In the form factor M.2 2230 are presented the same capacity, but with the possibility of self-installation by users in the scrap M.2. The length of the drive is only 3 cm. In both cases, the chip includes a memory controller supporting the NVMe 1.2.1 protocol and the PCIe 3.0
x2 interface.
The drive does not have built-in DRAM memory. Buffering is carried out by allocating space in the system memory (Host Memory Buffer, HMB). It is also possible to work in the mode of transferring a TLC cell into a pseudo SLC. This will definitely speed up the work of the drives series , although the stated steady speeds are so good for a single-case SSD. It is reported that in the read mode the speed reaches 1520 MB / s, and in the write mode - 840 MB / s.
Toshiba BG3 SSD series is designed for budgetary use. The price of the issue is not reported. The drives will be supplied to OEMs via OEM channels. There is an opinion that the price of SSD of this series will be close to the cost of SATA HDD drives of similar capacity. If necessary, the new series models support the TCG Opal Version 2.01 data protection technology. Demonstration of the development will be held August 8 at the Flash Memory Summit 2017.
