Kioxia KCD8XPUG1T92 CD8P-R & KCMYXVUG3T20 CM7-V PCIe 5.0 SSDs
The Kioxia CM7-V 3.2TB PCIe 5.0 SSD did allow for the best performance of all tested SSDs. The enterprise PCIe 4.0 SSDs were much faster than the Corsair MP700 PCIe 5.0 consumer drives to not much surprise. The CD8P-R read-intensive SSD was still performing very well for this read-write PostgreSQL database server workload.
The gains of these Kioxia PCIe 5.0 SSDs were incremental over the enterprise PCIe 4.0 SSDs but over the coming months we'll likely see the introduction of more capable PCIe 5.0 enterprise SSDs.
With the MariaDB 11.5 database server these Kioxia PCIe 5.0 SSDs were also delivering the best performance on this AMD EPYC 8004 series Siena server, albeit not by any dramatic margins compared to the enterprise PCIe 4.0 SSDs that are much more mature and widely available than the hard time shopping for enterprise PCIe 5.0 solid state drives.
That's the quick overview / initial experience of the Kioxia KCD8XPUG1T92 CD8P-R and KCMYXVUG3T20 CM7-V PCIe 5.0 enterprise SSDs now that they've finally arrived in the lab after a lengthy shopping experience in looking out for readily available PCIe 5.0 enterprise drives. Hopefully the availability of PCIe 5.0 enterprise SSDs will improve over the coming months as more PCIe 5.0 servers come to market and also seeing more enhanced PCIe 5.0 enterprise SSDs introduced for feeding the next generation server platforms.
