What to Check Before Buying a 4TB External SSD
USB 3.2 Gen 2 (10 Gbps, ~1,000 MB/s) is the sweet spot. 20 Gbps and Thunderbolt models cost far more and need matching ports to matter.
Compact externals throttle when hot. If you move 100GB+ files regularly, look for reviews measuring sustained write, not the sticker number.
IP-rated, drop-resistant models cost more. Worth it for field work, irrelevant on a desk.
3-5 years typical. Portable drives lead hard lives - warranty length matters more than for internals.
