SSDs
Choose storage that fits your board and workload.
Capacity
How much data the drive can store. Check that specifications describe the exact capacity you intend to buy.
Interface and shape
SATA and NVMe describe interfaces; M.2 is a form factor. Match interface, length, and connector to your system.
Read speed and endurance
Sequential speed is an advertised maximum, not a game-loading result. Endurance describes the rated write workload, usually in TBW.
