How to choose an external SSD
These factors decide real-world speed and reliability.
Interface (USB 3.2 vs USB4/Thunderbolt)
The port sets the speed ceiling. USB 3.2 Gen 2 (10Gbps) suits most people; USB4/Thunderbolt unlocks the fastest drives but needs a matching port.
Capacity
Buy a little more than you think you need. 1TB is the sweet spot for most; creators and gamers benefit from 2TB or more.
Durability
If the drive travels, look for an IP rating and drop resistance. SSDs have no moving parts, so they already survive bumps better than hard drives.
Real-world speed
Sustained write speed matters more than peak burst numbers, especially when copying large folders. Look for consistency, not just a headline figure.
Compatibility
Check the connector and whether you need to reformat for your computer or console. A USB-C drive with an included USB-A adapter is the most flexible.
How they compare
Specs and jargon, explained
The terms you will see on spec sheets and product pages, in plain English:
| Term | What it means for you |
|---|---|
| USB 3.2 Gen 2 (10Gbps) | A common, fast interface good for backups and most work. Often labelled simply '10Gbps'. |
| USB4 / Thunderbolt | The fastest consumer interface, ideal for video editing off the drive — but needs a matching port. |
| Sustained vs peak speed | Peak is the burst number; sustained is what you get copying large folders. Sustained matters more. |
| IP rating | Dust and water resistance — e.g. IP65. Pair with drop ratings for true ruggedness. |
| TBW / endurance | Total bytes written the drive is rated for. Plenty for normal use; only heavy daily writers need to check. |
