ADATA SD700 External 256GB SSD Review

To test the drive we re-formatted from the out of the box, factory formatted FAT32 to NTFS.

Crystalmark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using V3.0.3.

The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Measure your storage systems performance with various transfer sizes and test lengths for reads and writes. Several options are available to customize
your performance measurement including queue depth, overlapped I/O and even a comparison mode with the option to run
continuously.

Use ATTO Disk Benchmark to test any manufacturers RAID controllers, storage controllers, host adapters, hard drives and
SSD drives and notice that ATTO products will consistently provide the highest level of performance to your storage.

AS SSD is a great free tool designed just for benching Solid State Drives. It performs an array of sequential read and write tests, as well as random read and write tests with sequential access times over a portion of the drive. AS SSD includes a sub suite of benchmarks with various file pattern algorithms but this is difficult in trying to judge accurate performance figures.

ADATA quote Sequential read/write figures for the drive at up 440MB/s and 430MB/respectively. Tested with the ATTO benchmark the drive fell short of the maximum Sequential read figure at 412MB/s but when it came to writes it matched the official figure at 431MB/s. Under the more stringent AS SSD test, the Sequential performance figures dropped away, particularly the writes, scoring just 395MB/s.
