Crucial X8 Portable SSD Review (1TB)


The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance. For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs. 

Sequential performance is as advertised on this SSD but we have seen low 4K read and write results in a few tests now.  In most usage scenarios, this is not an issue if concern as these types of drives are typically used for the storage of media, and not smaller OS files.


Anvil’s Storage Utilities (ASU) are the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.


TxBench is one of our newly discovered benchmarks that we works much the same as Crystal Diskmark, but with several other features.  Advanced load benchmarking can be configured, as well as full drive information and data erasing via secure erase, enhanced secure erase, TRIM and overwriting.  Simply click on the title for a free copy.


The Crucial X8 External SSD is Crucial’s first product of this type as it would have previously formed part of the Lexar Division of Micron prior to that sale.  The X8 is a solid SSD, based on the Crucial P1 M.2 SSD, with decent 10Gbps performance up t0 1050MB/s, a 3-year warranty and great pricing.

Unless you are looking specifically for a faster Thunderbolt 3 device that might get you up to 2.8GB/s data transfer speeds, this SSD is definitely recommended for typical consumer storage applications.
