DRAM cacheiDRAM is a memory chip on the drive. HMB is a drive without DRAM that borrows host memory. None has neither. HMB not stated is a drive without DRAM where no source says whether it borrows host memory. An external drive counts when a source names the cache of the drive inside.

Component sidesiWhether chips sit on one or both sides of the board. Thin laptops and some handhelds need single-sided drives. M.2 drives only. The M.2 module code states it: S is single-sided and D is double-sided, e.g. 2280-S3-M or 2280-D5-M.
