Back up and access your files faster than ever with the Samsung X5 Thunderbolt 3 Portable SSD. Lightweight yet durable, this portable hard drive offers impressive write speeds. The X5 comes in three sizes: 500GB, 1TB, and 2TB. For the 500GB edition, it has write speeds up to 2,100MB/s. This device takes things up a notch for both the 1TB and 2TB editions by offering write speeds up to 2,300MB/s. For all models, the X5 has a read speed of up to 2,800MB/s. These figures are truly revolutionary as they’re 5.2 times faster than most portable SSDs and 25.5 times faster than external HDDs. For example, you can transfer a 20GB 4K UHD video in only 12 seconds. Thanks to Thunderbolt 3 technology, all of this is possible every time you plug in. This exceptional ability comes in a shock-resistant internal frame and rugged metal exterior that can survive 6.6-foot drops.
