ADATA Ultimate SU800 240GB SSD Review


Partial and Full Drive Performance

While it is important to know how a drive will perform under optimal conditions, more realistic scenarios are just as important. Knowing if a solid state drive will behave differently when partially or even nearly full than when it is empty is very important information to know. To quickly and accurately show this crucial information we have first filled the drive to 50% capacity and re-tested using both synthetic and real world tests. After the completion of this we then re-test at 75% and 90% of full capacity.

Synthetic Test Results

For our synthetic testing we have opted for our standard PCMark 7 test.

Real World Results

For a real world application we have opted for a modified version of our standard Windows 7 Start Up test. Unlike our standard Windows 7 image this image is based on a working system that has been upgraded numerous times of the past few years and represents an even more realistic real world test.

These results are precisely why the Silicon Motion SM2258 controller is widely regarded as being worthy of its low asking price. Essentially, this controller cannot handle the demands of full drive scenarios even remotely as well as its competition from Toshiba, Marvell, or even PHISON. This controller, and not the NAND, is the Achilles’ Heel of the SU800.
