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

Test System for the Samsung Portable SSD X5

The test system used was a Schenker SLIM 14 with a Thunderbolt 3 connection and full connectivity.


According to Samsung, the Portable SSD X5 offers speeds of up to 2,800 MB/s. This makes it almost as fast as the internal NVMe SSDs and even surpasses some models. In our test, the Portable SSD X5 can also deliver these values. It is noticeable, however, that the temperature rises noticeably during prolonged use and the SSD then unfortunately also throttles. Therefore we have attached several ATTO Disk Benchmark Screenshots. In normal operation, however, this will rarely be achieved and even throttled the speed is even higher than with an external hard disk with magnetic disk.

In our test we did not activate the AES encryption in order not to slow down the speed.
