NAND Type

TLC is the mainstream flash type with a solid balance of speed and endurance. QLC costs less per gigabyte but slows more under heavy writes.

DRAM Cache

A DRAM cache gives steadier performance under heavy or random workloads. Drives without one are usually fine for everyday use.

Sided

Whether the flash chips are mounted on one side of the circuit board or both. Single-sided drives fit in more laptops and handhelds with tight internal clearance, and their heatsinks are an easier fit in the PS5's expansion bay too.
