Adata SD700 External SSD Review (256GB) – A Rugged Companion For Your Travels


ATTO Disk Benchmark is a relatively easy-to-use benchmark tool, which happens to be the benchmark of choice for many manufacturers. ATTO uses compressible data rather than random data, which results in higher performance and thus, higher benchmark scores. In our testing, we have selected the transfer size to range from 0.5KB to 8192KB, and have set the total length of the test to be 256MB.

Our first results are very good, almost in line with the listed read/write speeds of up to 440 MB/s – the lower results could be attributed to the usage prior to us obtaining the drive.


Crystal Disk Benchmark is visually straightforward and is used for measuring the speeds at which your storage device reads and writes in both compressible (oFill/1Fill) and random, mostly incompressible, data. Random data is more consistent with the everyday use of a computer, such as transferring videos, pictures, and music. We run the benchmark twice, using oFill data first, and then proceeding to test with random data. Since results typically return with nearly identical scores, we only include the results for random data samples.

Similarly to ATTO, Crystal Disk Mark returned positive results again almost reaching the listed max read/write speeds, and coming up just a bit shy.


AS SSD Benchmark uses incompressible data in their testing of SSDs, essentially providing results that would be consistent with using the heaviest workload, thus lower speeds are expected. Transfer speeds (MB/s) are seen below:

Another interesting feature of the AS SSD Benchmark is that it also can test durations and speeds of copying various files, this is an important test for our digital media professionals who require top transfer speeds.

The ADATA SD700 is performing well – for a used device – again almost reaching the max read/write speeds, and pushing out some decent transfer speeds.


Anvil Storage Utilities is essentially an all-in-one tool for all of your SSD benchmarking needs. Anvil can be used for basic consumer testing, as well as endurance testing and threaded I/O read, write and mixed tests. It displays data regarding the SSD, and even about your system.

Our all-in-one benchmark tool, Anvil’s Storage Utility, returned again decent results just below the list specs.
