WD Blue SN5100 500GB NVMe M.2 SSD
The one 500 GB drive filed under M.2 NVMe Gen 5 is the WD Blue SN5100 500GB (WDS500G5B0E-00CPE0). Its own spec sheet lists it as a PCIe Gen4 NVMe M.2 SSD, not a Gen 5 drive, with read/write speeds of up to 6600/5600 MB/s. It ships without a heatsink, and WD covers it with a 5 year warranty.
Most PCIe Gen 5 SSDs come in 1 TB and larger capacities. At 500 GB, a Gen4 drive like the SN5100 suits a boot or game drive. In a Gen 5 M.2 slot it runs at its Gen4 speed.
