Toshiba has already demonstrated a new generation of CM6 and CD6 series.SSDSupporting PCIe 4.0 X4 will replace current PCIe 3.0 CM5 and CD5, respectively, for enterprise and data center markets. The former is U.3 interface, and the latter supports dual PCIe interface.
Toshiba BCiS 96 layer stacked 3D TLC flash memory particles are used for both. The peak reading speed can reach 6.7GB/s.
At the same time, Toshiba is also developing the XD5 series of follow-up XD6, for ultra-large data centers, more powerful with Oh low power consumption, low latency, and different from CM, CD series of high-performance, new features.
XD5 uses M.22110 CCTV, XD6 will add EDSFF E1.S (1U Short). In fact, Toshiba is very interested in EDSFF series interfaces, followed by E1.L, E3.S, E3.L and other specifications.
However, Toshiba's PCI 4.0 SSD is still far from mass production. CM6 and CD6 series will be the fastest next year, while XD6 will be after 2020.
As for the consumer market, Toshiba SSD is basically OEM, so there is no need to rush to PCIe 4.0.
XG6,XG6-P 's next-generation XG7 may not be available until Toshiba's 100-tier stack flash memory is ready, and it is Toshiba's practice to match the new SSD with new flash memory.
