Kioxia has announced that they have a prototype of PCIe SSD drive 5.0 on the WeChat social network. This SSD drive is twice as fast, with sequential read and write speeds of up to 14GB / s and 7GB / s, respectively.
Kiioxia also has a new 6-layer BiCS 162 NAND memory in development. Represents a 103% and 67% performance increase over existing PCIe 4.0 drives. The prototype was an SSD server called CD7. In terms of capacity, it will range from 1,6TB to 30TB, with one to three drive writes per day. Unlike the CD5 and C6, the CD7 has an eight channel memory controller.
Advances in memory technology
The FL6 is the next generation model of the CM6. Due to its high endurance of 60 disk writes per day and storage capacities ranging from 800GB to 3,2TB, this Kioxia PCIe 5.0 SSD is designed to handle demanding read and write workloads. Compared to its predecessor, it is 7% and 135% faster in both random reading and writing than the previous version.
Xpoint is a reference to the 3D XPoint products from Intel and Micron, respectively. Intel markets these solid state drives under the Optane brand name and they are intended to serve as a transition step between DRAM and NAND memory.
The Bics 6 memory will have a total of 162 layers. This will make it more difficult to climb when there are a large number of layers, but Kioxia claims this has been handled by making each layer smaller. thus, the amount of data has increased in density. For this iteration, the power circuit also moves under the chip instead of alongside it, improving efficiency. A BiCS 6 chip would be 40% smaller in size compared to a BiCS 5 chip.
