Marvell QLC-capable flash controller can do 670k IOPS

Half an hour ago I wrote about the QLC-based Intel SSD 660p and now there's news of a new QLC-capable controller from Marvell. The quad-bit-per-cell NAND flash memory is cheaper but has even lower endurance than triple-bit-per-cell (TLC) NAND flash memory. Over at CES 2018, Tom's Hardware heard that various companies are working on QLC-based SSDs.

One of the upcoming QLC-capable controllers is a new Marvell model that will replace the existing NVMe 1.1 Eldora (88SS1093). The unnamed controller will target the consumer, cloud data center, and enterprise segments.

QLC NAND flash memory requires enhanced error correction technology and one of the key features in the new Marvell controller is NANDEdge ECC technology.

Tom's Hardware saw the controller in action at CES 2018 and reports it can do 3500MB/s and 670,000 IOPS in combination with 3D TLC flash memory. The availability of the first disks with this controller is unknown, but it will probably be later rather than sooner.
