A-DATA S592 128GB SSD Review

Read Bandwidth

For this benchmark, HDTach was used. It shows the potential read speed which you are likely to experience with these hard drives. The long test was run to give a slightly more accurate picture.

We don’t put much stock in Burst speed readings and this goes double for SSD based hard drives. The main reason we include it is to show what under perfect conditions a given drive is capable of; but the more important number is the Average Speed number. This number will tell you what to expect from a given drive in normal, day to day operations. The higher the average, the faster your entire system will seem.


Well this is certainly not the greatest way to start the performance section of the review. Of course, this difference is due to the ancient 1279 firmware on this drive versus the later 1.3 / 1571 we were able to use in previous reviews. It will certainly be interesting to see how this older firmware will stand up to the newer ones…as we fully expect this to be the only difference in performance.

Write Performance

For this benchmark HD Tune Pro was used. To run the write benchmark on a drive, you must first remove all partitions from that drive and then and only then will it allow you to run this test. Unlike some other benchmarking utilities the HD Tune Pro writes across the full area of the drive, thus it easily shows any weakness a drive may have.


Older firmware or not, this SSD seems to be leaning more towards the Vertex end of the performance spectrum rather than that of the Falcon. It seems that while OCZ has tweaked their firmware more than the other companies, this particular SSD has surprisingly good capabilities and we can only imagine what it would do with the latest and greatest firmware.
