Passively-cooled SSDs

M.2 SSDs are amazing. They are convenient, they are easy to implement, they are incredibly fast. They also run hot. In fact, a heat sink is now mandatory to achieve the advertised PCIe 4.0 performance.

Two of the first Gen4 PCIe SSDs available are from Sabrent (1TB / 2TB) and Corsair (1TB / 2TB). These speed demons deliver up to 5000MB/sec sequential read, that's ten times the performance of many SATA SSDs, and fifty times faster than most hard disk drives, but do require extra cooling.
