Crucial X6 4TB Portable SSD Review

Large File Transfer and Game Load Benchmarks

Real World File Transfer

The first custom test that we are going to do is to show how fast each portable drive can read and write a compressed folder. For this we backed up a Steam copy of PlayerUnknown’s Battlegrounds for the test file. The compressed folder was 30.5 GB in size and we moved it to the portable SSD and then performed read test of that file.

Benchmark Results: The Crucial X6 4TB External Drive finished this test with 455.40 MB/s on reading the compressed file and 329.67 MB/s writing that file. Middle of the pack scores as you can see from the results above. 

Crucial X6 4TB Call of Duty Write

Our hardest test is to copy the entire the Call of Duty: Modern Warfare game directory and then move it to the portable SSD. This file is just shy of 200GB in size and really hammers the portable SSD being tested as it is one long sustained write operation. The Crucial X6 4TB external drive finished this test at 416.36 MB/s and that that result places this model in the middle of our performance chart.

Game Load Time Testing

Game Load Time Testing
To test game load times we used the benchmark for the game title Final Fantasy XIV: Shadowbringers that was released in July 2019. We bumped up the resolution from 1080P to 1440P, but other than that we left all the settings at their stock values. Pretty much every SSD on the market today claims to be aimed at gamers, so this test shows you how the drives we tested perform on an actual game title in a series that every gamer has heard of.

Benchmark Results: We’ve tested over dozens of portable SSDs on this system and none have ever had issues running this benchmark until we tried it on the Crucial X6 4TB drive. The benchmark application launches, but as soon as you start the actual benchmark it hangs and stops responding. The end result is the same on both Intel and AMD test platforms. We’ve let both Crucial and Phison know about this issue.
