Datacenter NVMe drives are not tiny little M.2 drives with heat problems. They are long slab hotswap cards, usually wired up with U.2. They don't have heat problems.
Pretty much the only NVMe drives with problems are these first-gen PCIe 4.0 drives because they're all based on overclocked PCIe 3 controllers. Then shoved into a tiny space with no fan under the GPU.

in their test fde reduced throughput from 1126 MB/s to 147 MB/s which is several times more than "halves"Last edited by pal666; 29 March 2020, 07:51 AM.
