Kioxia Unveils 162-layer BiCS 6 NAND Memory and a Prototype PCIe 5.0 Solid State Drive up-to 30TB

Kioxia Unveils 162-layer BiCS 6 NAND Memory and a Prototype PCIe 5.0 Solid State Drive up-to 30TB

Kioxia has revealed a prototype PCIe 5.0 SSD on WeChat in China. It's twice as fast, with sequential read and write rates of up to 14 GB/s and 7 GB/s, respectively. It also has Kioxia's new 162-layer bics 6 memory.

This is a 103 percent and 67% performance increase over existing PCIe 4.0 solutions. The prototype was a server SSD named CD7. In terms of capacity, it will range from 1.6 TB to 30 TB, with one to three drive writes each day. Unlike the CD5 and C6, the CD7 has an eight-channel memory controller. 

The FL6 is the next-generation model of the CM6. Because of its high endurance (60 drive writes per day) and large storage capacity (ranging from 800GB to 3.2TB), this PCIe 4.0 SSD is primarily suitable for processing demanding read and write workloads. If you compare it to its predecessor, it is 7 percent and 135 percent faster in both random reading and writing than the previous version. "Xpoint," as Kioxia refers to its FL6 SSD, is a reference to the 3D XPoint products from Intel and Micron, respectively. These solid-state drives (SSDs) are marketed by Intel under the Optane brand name and are intended to serve as a transitional step between DRAM and NAND memory.

Bics 6 memory is an excellent beginning. It has a total of 162 layers. It becomes more difficult to scale when there are a large number of layers, however Kioxia claims that this has been handled by making each layer itself smaller. As a result, the amount of data has increased in density. For this iteration, the power circuit is also moved under the chip rather than next to it, which improves efficiency. A bics 6 chip would be 40% lower in size when compared to a bics 5 chip.

I knew my brand new comp would be out of date in a year or two but never thought the SSD would suffer the same fate. PCIe5 - 14GB/s and upto 30 TBs sound like M.2 ssd's are about to move on.

these are likely multiple m.2 sticks or using m.2 controllers embedded on a card

The pci express 5.0 nvmes are going to be very , very fast ! The new controllers are insanely fast and iops trough the roof. This makes my Sabrent Rocket Plus 2TB x4 Raid0 obsolete :eek: .

These speeds don't matter much as long we are bottlenecked by the CPU and file system on Windows.
We really need Direct Storage to take advantage of these speeds.
Until then, this is only useful in a handful of situations.

^^ This right here 100% true. The only way to reach reasonable speed on high bandwith , high speed , high iops storage set up is to overclock the cpu and tweak the windows 10 file system , on my case i test this with fast nvme's 4.0 in Raid0 on a highpoint Raid card that runs at pci exprees 4.0 x8 , even 5.7Ghz Rocketlake is not enough , as it keeps scaling in benchmarks as ssd / cristal disk , etc ... sad but true :/ , cpu bottleneck and file system is real.

Direct Storage cannot come soon enough !
