ADATA Ultimate SU800 240GB SSD Review
Crystal DiskMark is designed to quickly test the performance of your drives. Currently, the program allows us to measure sequential and random read/write speeds, and also allows us to set the number of tests iterations to run. We left the number of tests at 5 and the size at 100MB.
While there are numerous suites of tests that make up PCMark 7, only one is pertinent: the HDD Suite. The HDD Suite consists of numerous tests that try and replicate real world drive usage. Everything from how long a simulated virus scan takes to complete, to MS Vista start up time to game load time is tested in these core tests; however, we do not consider this anything other than just another suite of synthetic tests. For this reason, while each test is scored individually, we have opted to include only the overall score.
As you can see, the low queue depth / small file performance is pretty decent and fairly comparable to similarly priced models. Of course, once the queue depths get deeper the performance of the SU800 does quickly fall further and further behind the competition. Basically, the SM2258 may be an ‘improved’ SM2256 but it is obviously still an entry-level controller. Overall, given the price of this drive, this level of performance is more than acceptable.
