Buying Guide: An Overview
Check your motherboard before buying: a Gen5 SSD needs a compatible PCIe 5.0 M.2 slot to reach full speed, while Gen4 drives work on more platforms. DRAM can help with sustained workloads, and TLC NAND generally offers stronger endurance balance than QLC. Check TBW for heavy writing, and plan for a heatsink with Gen5 drives. For most users, 1TB is the minimum; 2TB is the better long-term choice.
Choose a PCIe Gen4 SSD such as the Samsung 990 Pro or WD Black SN850X for excellent gaming and everyday performance with broad compatibility. Move to Gen5 for large-scale video editing, AI datasets, professional workloads, and frequent transfers of massive files where higher sequential bandwidth can make a measurable difference.
