Best SSD: Samsung T5

Samsung T5


Unlike traditional hard drives, solid-state drives store data on an integrated circuit and don't use moving parts—meaning there's less risk of losing data due to mechanical failure or damage to individual parts. The Samsung T5 external SSD is a great option, and it comes in a range of sizes from 250GB to 2TB.

Featuring an all-metal construction, the body of the SSD is rated to withstand drops and falls from as high as 6.6 feet. The included USB-C cable gives you transfer speeds up to 540MB per second (4.9 times faster than traditional hard disk drives), allowing you to quickly and easily move large projects from your computer to the drive or vice versa. With the companion app for smartphones and tablets, you can set a password to access the drive and manage firmware updates. The SSD is also protected by 256-bit AES encryption.
