3D QLC NAND promises to become a significant phenomenon on the consumer SSD market thanks to its relatively low cost per gigabyte, further pushing down already dropping SSD prices. As one of the leading suppliers of turnkey SSDs, Phison for its part demonstrated QLC SSD prototypes at this year's Computex, using QLC NAND from both Micron and Toshiba. To date, Phison has validated three of its controllers for use with 3D QLC NAND flash memory: two SATA controllers and one PCIe controller. The PS3111-S11T and PS3113-S13T are aimed at entry-level SATA SSDs, whereas the PS5013-E13T is designed for inexpensive PCIe 3.0 x4 NVMe drives. The S13T and the E13T support Phison’s 4th Generation implementation of LDPC-based ECC as well as other modern features designed to...
