Best External SSDs

We reviewed portable external SSDs across read and write speeds, drop and water resistance, physical size, and price per gigabyte. The picks cover the most popular 1TB tier, which balances cost and capacity for most users. All five are bus-powered, they draw power from the USB cable with no separate power adapter required.

The spec buyers confuse most often is USB standard labeling. USB 3.2 Gen 2 (10Gbps) drives, like the Samsung T7 and SanDisk Extreme, deliver real-world read speeds around 900-1050MB/s. USB 3.2 Gen 2x2 (20Gbps) drives, like the Samsung T9, push up to 2000MB/s but require a compatible port on your computer to realize that speed advantage. Most laptops and PCs sold before 2022 have Gen 2 ports, not Gen 2x2. Check your port spec before spending extra for a Gen 2x2 drive.

IP ratings tell you different things about protection. IP55 means protected against light water spray. IP65 means protected against water jets from any direction. The SanDisk Extreme series carries IP65 water resistance, making it genuinely field-rugged. If you use a portable SSD on job sites, in camera bags, or outdoors, IP65 is a meaningful upgrade over an unrated drive.
