Crucial T705 NVMe M.2 SSD, Up to 14,500MB/s Read, PCIe 5.0, 2TB–4TB

Gen5 throughput only appears in a PCIe 5.0 M.2 socket. Dropped into a Gen4 board this drive still runs, at Gen4 speed, and the premium is wasted — check the slot before ordering.

This is the bare version, so the motherboard's own M.2 heatsink or an aftermarket cooler is required; Gen5 controllers run hot enough to throttle without one. It sits above the Crucial T700 PCIe Gen5 NVMe 1TB SSD on sequential ceiling.
