| Kioxia Releases First PCIe 4.0 SSDs: CD6 & CM6 Following through on their roadmap for transitioning to PCIe 4.0, Kioxia (formerly Toshiba Memory) has announced the availability of their first two PCIe 4.0 SSDs. The CD6 and CM6 SSDs target the datacenter and enterprise markets respectively, with a common hardware platform but some differences in configuration, features and performance. The CD6 and CM6 use a next-generation SSD controller from Kioxia. As with most NVMe controller designs, the switch to PCIe 4.0 has triggered a switch to 16nm FinFET fabrication in order to permit higher performance within the same power limits. The CM6 uses an 18-channel controller while the CD6 gets a slightly cut-down 16-channel version. Both drives are using Kioxia's 96L 3D TLC NAND, which helps improve performance, especially for write. Both models will feature capacities ranging from 800GB up to 15.36TB, and the CM6 will also be getting a 30.72TB model a bit later. The drives use the 2.5"/15mm U.3 form factor, backwards compatible with U.2 backplanes, but also supporting newer tri-mode SAS/SATA/PCIe backplanes and HBAs. Kioxia believes they are the first to start shipping PCIe 4.0 U.3 drives to customers. https://www.anandtech.com/show/15537...0-ssds-cm6-cd6 |
