Micron is giving its datacenter one bit extra as the company is close to rolling out disks with 4-bits-per-cell for the nearline storage drive market. The new memory is expected to have a shorter endurance than TLC NAND flash memory but can deliver more capacity for the same price. AnandTech writes Micron plans to debut QLC-based SSDs with SATA interface later this year.
The drive will be positioned below the existing 5200-series SSDs and will be aimed primarily at read intensive applications (or the so-called WORM — write once, read many workloads). The QLC-based SSD will have a feature set aimed at hyperscale datacenters and will compete for the place currently occupied by high-capacity 7200 RPM HDDs, reports The Register.
At the A3 Technology Live conference in London last week, Micron revealed a wafer with 512Gb (64GB) 3D QLC NAND flash memory chips. These disks will fill a gap between high-capacity SSDs and high-performance SSDs.
