Samsung Portable SSD X5: New External NVMe SSD with Thunderbolt 3 in Review

Just last year Samsung limited its Portable SSD T5 to USB 3.1. At the IFA Samsung will show the Portable SSD X5, which no longer has this limitation. The external NVMe SSD connects via Thunderbolt 3 for speeds up to 2,800 megabytes per second. With 500GB, 1TB or 2TB of storage, the mobile SSD offers room for many files. We have already tested the new model.

The Samsung Portable SSD X5 comes in a high-quality metal and plastic housing. The red plastic feels relatively soft and very pleasant, while the metal provides a feeling of high quality. Compared to the previous T-series, the case has changed significantly and has unfortunately also become much heavier with 150 grams compared to 51 grams. This is mainly due to cooling elements, as the waste heat generated by the high speeds must be dissipated. The SSD is about the size of a small power bench, so it fits in any pocket, even if it’s bigger than its predecessors.

As with all SSDs, the data is much better protected against external influences because there is no magnetic disk that could break in a fall.

The Samsung Portable SSD X5 now uses a Thunderbolt 3 port that doesn’t differ visually from the USB Type C port of the previous Portable SSD T5, but is significantly faster. Only a Thunderbolt cable is included and no USB cable anymore.
