Samsung has introduced a portable X-series NVMe SSD with support for Thunderbolt 3. The new Samsung Portable SSD X5, with its 40Gbps bandwidth, can hit read speeds of 2,800 MB/s, which is several times faster than SATA-based portable SSDs. The Portable SSD X5 costs $399.99 for the 500GB model, $699.99 for the 1TB model, and $1,399.99 for the 2TB premium version. It ships beginning September 3rd.

But since this is specifically a Thunderbolt 3 drive, laptops that only support USB won’t be compatible. You’ll definitely need a recent, high-end machine to use the X5 and take advantage of what it can do.

The SSD is meant to handle 4K video editing, real-time 3D rendering, and high-resolution RAW files. You can transfer files at up to 2,300 MB/s, meaning a 20GB file could be moved in just 12 seconds.

The metal, shock-resistant frame is supposed to be able to take a fall of up to two meters. It’s got a glossy look, but includes a non-slip bottom mat to prevent accidents. Samsung backs the drive with a three-year limited warranty. At 4.7 inches tall, 2.4 inches wide, and 0.8 inches thick, it’s a bit smaller (albeit thicker) than most flagship smartphones.
