With the generous announcement of Intel and Micron, QLC Flash finally ushered in the golden period of development.
QLC flash memory can hold 4 bits of data per cell, which is one-third more than TLC, that is, the capacity density under the same area will increase by 33%. However, the resulting drawback is that theoretical PE (programmed erase/write cycles ) Only 1000 times, is 1/3 of TLC flash memory.
Maxio (Hangzhou United Technology) recently demonstrated Based on Intel 3D QLC flash SSD samples, capacity up to 4TB.
The master control is, of course, its own, model number is MAS0902A-B2C, built on GF 14nm process, supports AgileECC2 error correction, SLC cache, virtual partition recovery and other features.
however, It may be that the main control is still not advanced enough. The SSD particles have only 500 PEs. According to the design life of five years, DWRD is only less than 0.3 (not considering write amplification).
Of course, the company said that the flash memory is an early version and the main control also has debugging space, which is certainly higher than 500PE after mass production.
Performance aspects , Read 562MB/s continuously, Write 520MB/s , For SATA 3, is considered excellent. The company also said that if you want to further speed, you can buy MAS0901 master with DRAM.
