Last week, Kioxia completed its line of enterprise and data center PCIe 4.0 SSDs with the announcement of the XD6. Now they are 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 the sequential write speed by 60% over the XG6 series, thanks to PCIe 4.0 support and a new SSD controller. Based on the XG6 specs, this should be at least 6.3 GB / s read and 4.6 GB / s write for the XG7. This might not be fast enough for high-end consumer SSDs sold at retail, but for an OEM-only client SSD, it’s still blazingly fast.
For the first time, Kioxia (formerly Toshiba Memory) is presenting the higher performance / higher capacity P models alongside the base models of its XG series. The XG7 will be available in capacities ranging from 256GB to 1TB, and the XG7-P will offer capacities of 2TB and 4TB. This likely makes the XG7-P the first customer OEM SSD to add a 4TB NVMe option. .
Full performance specifications for the XG7 (-P) family have yet to be 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 last two generations, we are not receiving test samples from the XG7, so we will have to wait until next year to get a first-time experience. main with the PCIe 4.0 solution from Kioxia.
