Toshiba Prepare NVMe SSD XG5 With 64-Layer BiCS

Through Dell World, Toshiba features their newest laptop that works with NAND 64-layer for the first time, known as NVMe SSD XG5, designed for mainstream systems to high performance.

The Toshiba XG5 uses four PCI Express 3.0 lines to achieve up to 3000 MBps of READ performance sequentially and 2100 MBps WRITE performance sequentially from its 3-bit per cell (TLC) NAND 3D.

The new 64-layer BiCS NAND support is expected to hijack the sophisticated workload at high speed, but Toshiba does not seem to be disclosing random performance for a typical configuration because each OEM will design constraints based on thermal and electrical consumption requirements.

Regarding its own power consumption, the Toshiba XG5 SSD uses less than 4.6W in read state (Read) on, and can even drop to 3W for active writing (Write).

While idle consumption is only about 3mW. The drive will initially be marketed as an OEM SSD client with capacities ranging from 256GB to 1TB.

This latest series will use 256Gbit BiCS and 512Gbit BiCS mixtures, depending on the size of its capacity. The aftermarket buyers will receive a modified version under the OCZ RD product line. (The same thing happened on RD400 which is similar to Toshiba XG3).

Given that Toshiba has to complete the time-consuming qualification of some OEM customers then it is unlikely that there will be any retail branded models until the end of this year.

With drives on display at Dell World, it can be assumed that XG5 will be in the company’s back-to-school system later this year.

Toshiba and its manufacturing partner Western Digital plans to utilize BiCS for a number of devices by 2017.

NAND 3D technology will surpass the NAND planar in output bits produced and delivered in the second half of 2017. One representative of Toshiba even revealed that the latest SSD XG5 will provide similar XG3 resistance with 15 M Planar MLC technology.

So far it is still unknown how well BiCS compares to the NAND 64-layer 3D technology made by Samsung and IMFT. However, a definite increase in output bits will reduce supply problems and impact on current SSD price adjustments.

The NAND race seems to be heating up again with the latest additional 3D technology that is able to reset clock resilience and spur lower prices that help users adapt.
