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.
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.
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.

Looking at the above performance results, we can see the price of falling back to using Serial ATA, vice the all to common NVMe that we see these days. Listed performance is as stated but looking at the low 4k random reads and writes, they are much lower than we have seen in some time. To many this may not mean anything at all, unless of course you are storing operating system or very small files that must be retrieved quickly for some reason. This most likely also accounts for the 3-year warranty, vice industry standard five that we see typically these days.
All in all, the Crucial X6 is one of the most compact storage devices we have seen to date and that is its biggest benefit. It’s pricing, at the comparative level, is good…until we put it beside its bigger brother the X8. Right now at Amazon, we can purchase the faster performing X8 which also includes both Type-C adapters for $149 while the newer and smaller X6 comes in at $154 before buying the Type-C to Type-A adapter.
It’s a choice that Crucial doesn’t mind you making, the smaller X6 or the slightly larger X8 with twice the speed.
