The new SSDs include the CM6 and CD6 Series PCIe 4.0 NVMe SSDs. According to the company, the new drives can hit speeds as high as 6.9GB/s. ![](https://www.storagereview.com//wp-content/uploads/2020/02/StorageReview-KIOXIA-PCIe4-SSDs.jpg) Back during the Flash Memory Summit, KIOXIA (still under the Toshiba banner at the time) first announced and demoed the CM6 and CD6 series of SSDs. This PCIe 4.0 SSDs are made possible through the release of the AMD EPYC 7002 series of CPUs that brings PCIe 4.0 support to x86 servers. KIOXIA was the first to demo the drives and are now the first to release the drives. Aside from faster speeds, the new drives include features such as in-band NVMe- MI, persistent event log and namespace granularity. Both drives are also SFF-TA-1001 conformant (U.3), which allows them to be used in tri-mode enabled backplanes, which can accept SAS, SATA or NVMe SSDs. ![]() Let’s look at the enterprise drive first. The CM6 Series is dual-ported for high availability. The CM6 is where the company gets their 6.9GB/s number along with 1.4 million IOPS from internal testing that KIOXIA didn’t go into detail about. This is about three times faster than PCIe Gen 3 and roughly twelve times faster than a SATA drive. The drive comes in capacities ranging from 800GB to 30.72TB. The ideal use cases for the CM6 are high-performance computing, artificial intelligence, caching layer, financial trading, and data analytics. ![]() For the data center, KIOXIA released the CD6 series. This drive is single ported and comes with performance claims of 1 million IOPS and 6.2GB/s. Capacities range from 960GB to 15.3TB. Ideal use cases include large-scale data center deployments and general-purpose applications, such as database, cloud computing, virtualized and containerized environments. Both the CD6 and CM6 offer a range of security and encryption options, including Self-Encryption (SED) and FIPS, and are on the UNH-IOL Integrator’s list for NVMe 1.4 device compatibility. **Availability** The KIOXIA CM6 and CD6 are shipping to customers now.
