Buying Guide

Choose the right interface

Match SATA 2.5" or M.2 NVMe to your motherboard: NVMe offers higher speeds, SATA is widely compatible

Prioritize usable capacity

Pick a drive size that fits your workflow—240–500GB covers OS plus key apps, while 120GB is best for basic boot drives

Check form factor and connector

Confirm whether you need 2.5"/7mm or M.2 2280 and whether your system supports PCIe Gen3/Gen4 lanes

Look for endurance and warranty

Higher TBW or multi-year warranties indicate longer expected life; vendors often publish these specs for SSDs

Balance speed vs. value

Sequential read/write and NVMe PCIe lanes matter for transfer-heavy tasks; SATA remains a cost-effective upgrade for general use

Consider bundled or dual-pack options

Dual-pack SATA bundles can offer more total capacity for cloning or multi-drive setups at a lower per-drive cost
