Intel launches 3D-based QLC NAND-based SSDs with PCI Express interface

  • July 23, 2018

Intel Corporation has announced the launch of a mass production of solid state drives based on a 3D flash QLC NAND (storing four bits of data in a single cell). The new SSDs use the PCI Express interface and are designed for data center (data center). It is noteworthy that a very concise announcement was made on Twitter, and then somewhat supplemented by an e-mail sent to the press.

It is known today that Intel solid state drives based on 64-layer 3D QLC NAND flash memory will be shipped in 2.5-inch form factor with U.2 interface using PCI Express 3.1 x4 bus and NVMe protocol. According to Intel, the new SSD will be part of the D5 family, indicating that the corporation is preparing to reorganize its range of drives.

As for the Intel D5 SSD based 3D QLC NAND, earlier this year, the company has already announced plans to introduce a 2.5-inch QLC drive capable of storing up to 20 TB of data. Apparently, the maximum capacity of D5 will be exactly that.

Considering the maximum capacity of the Intel D5 as well as the type of memory and its features, the manufacturer places this SSD as a solution for write-once read many, which requires relatively high performance both in terms of read speed and in terms of random operations. Micron positions its 5210 ION (based on 3D QLC NAND) as a replacement for hard drives. Apparently, the Intel D5 will be offered for approximately the same segment of the market, and the main advantage of the SSD will be precisely the performance that will be at times higher than the fastest HDD, both in absolute numbers and in IOPS / TBit conversion.
