ADATA Ultimate SU800 240GB 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 thus we no longer included it. The most 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 feel.


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.

Considering its asking price, this level of performance from a small capacity TLC SSD is pretty decent, so much so that the average consumer would never know this drive was not MLC based. The reason for these solid performance results is because the pseudo-SLC mode ‘cache’ design does indeed work. Of course, once this small amount of cache is exhausted, write performance does drop off a proverbial cliff until the controller can flush the data to the TLC NAND and allow more write requests to be pushed to the pseudo-SLC mode NAND.
