Frequently Asked Questions
External HDD vs external SSD — which should I buy?
External HDDs cost 3–5× less per terabyte than external SSDs, making them ideal for backups, media archives, and bulk storage where transfer speed is not critical. External SSDs are worth the premium for daily-use portable drives where you need fast access and the durability benefit of no moving parts.
How reliable are external hard drives?
External HDDs from WD and Seagate have similar reliability. The biggest risk is physical shock — always eject safely and avoid dropping a spinning drive. For critical data, follow the 3-2-1 backup rule: 3 copies, 2 different media types, 1 offsite.
