Crucial X8 Portable SSD Review (1TB)

Crucial has introduced a new product to the SSD fold as of late, this being the Crucial X8 Portable SSD.  This SSD is available in 500 and 1TB capacities and is a USB 3.2 Gen 2 (Type-C) external SSD that contains Crucial’s most recent M.2 release, the P1 NVMe M.2 SSD.  Specifications list this SSD as being capable of transfer speeds up to 1050MB/s and the X8 also comes with a 3-year warranty.

As far as looks and build go, this SSD is beyond reproach.  It is of an aluminum exterior with a black anodized shell and rubber ends, being 4″ long by 2″ wide.  It has a great feel to it.  Included in packaging are two cords, a Type-C to Type-C, Type-C to Type-A, a Quick Start manual and the drive itself.

Pricing can be found on Amazon and is $119.95 (500GB) and $164.95 (1TB) at the time of this report.


With respect to compatibility, the X8 is fully compatible with Win10, MacOS, PS4, XBox One, Android and even Ipad Pro.


ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.


We are not quite sure what exactly happened at the 4096kb read test level but read and write specs are dead on.


Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.
