Kioxia Announces XG7 PCIe 4.0 Client SSDs


Last week, Kioxia rounded out their lineup of PCIe 4.0 enterprise and datacenter SSDs with the . Now, they're bringing PCIe 4.0 support to their client NVMe product line with the new XG7 and XG7-P M.2 NVMe SSDs. The XG7 family doubles the sequential read speed and increases sequential write speed by 60% compared to the , thanks to the PCIe 4.0 support and a new SSD controller. Based on XG6 specs, this should be at least 6.3GB/s reads and 4.6GB/s writes for the XG7. That's may not be quite fast enough for high-end consumer SSDs sold at retail, but for an OEM-only client SSD it's still extremely fast. E3-1230 V3

For the first time, Kioxia (formerly Toshiba Memory) is introducing the higher performance/higher capacity -P models at the same time as the base models in their XG series. The XG7 will be available in capacities from 256GB to 1TB, and the XG7-P will offer 2TB and 4TB capacities. This likely makes the XG7-P the first client OEM SSD to add a 4TB NVMe option.

Full performance specs for the XG7(-P) family have not yet been announced, but in terms of features Kioxia is implementing NVMe 1.4 support and TCG Opal and TCG Pyrite security options. The XG7 and XG7-P will start appearing in pre-built systems in 2021. Unlike the past two generations, we're not getting review samples of the XG7, so we'll have to wait until next year to get first-hand experience with Kioxia's PCIe 4.0 solution.
