Buying Guide

Match capacity to your game library

Estimate space needs—indie libraries may fit on 64–256GB, while large AAA collections benefit from 512GB or higher

Look for UHS-I and Class ratings

UHS-I and Class 10 ratings indicate the sustained write performance needed for game installs and saves

Prioritize real-world transfer speeds

Advertised read speeds help with game load times; check measured MB/s for downloads and backups

Use reputable brands and adapters

Well-known manufacturers and included SD adapters reduce compatibility issues with docks and readers

Consider warranty and endurance

Longer warranties and cards designed for frequent rewrites offer better longevity for heavy digital libraries
