Buying Guide

Choose the right interface

Match SATA or NVMe M.2 to your motherboard slot to avoid compatibility issues and get expected boot performance

Prioritize peak and sustained read speed

Higher sequential and sustained reads improve boot and application load times more than peak burst figures alone

Pick adequate capacity for system and apps

Allocate at least 250–500GB for the OS, updates, and commonly used applications to prevent running low on space

Consider endurance and warranty

Look for stated TBW/endurance figures and multi-year warranties to predict lifespan under typical OS workloads

Factor form factor and cooling

M.2 drives may need heatsinks in tight or high-load systems; 2.5-inch SATA drives are bulkier but simpler to cool
