Yapt v0.3

Yapt v0.3 


Yapt (yet another performance test) is a benchmark recommended by a pair of drive manufacturers and was incredibly difficult to locate as it hasn’t been updated or used in quite some time.  That doesn’t make it irrelevant by any means though, as the benchmark is quite useful.  It creates a test file of about 100 MB in size and runs both random and sequential read and write tests with it while changing the data I/O size in the process.  The results are a good look at overall drive performance.

To an SSD, YAPT appears mostly sequential as its starting transfer size is a relatively large 64KB. Most SSD’s therefore turn in a horizontal line on even the ‘random’ tests. Here we see the 510 still ramping up in these tests – something not seen since the X25-M G1. Sequential reads were nipping at the heels of the pair of Vertex 3’s, while sequential writes fell neatly at the rated 315 MB/sec.
