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 is highly important since no one will leave their SSD without information on it. 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.
For our synthetic testing we have opted for our standard PCMark 7 test.
For a real world application we have opted for our standard Vista load time test.
While the Corsair GS 240GB’s performance does take a noticeable dip when there's a lot of data on it, this is to be expected since most modern controllers react in this manner. In the case of the LSI SF2281, the amount of performance lost is neither the worse nor the best example of this generation.
The type of NAND however does play a critical role in exactly how much of a hit it takes. For these situations, Toggle Mode NAND is superior to other types of NAND as it does help minimize the impact which remaining capacity has upon benchmark numbers. Much like other tests which really stress the controller, this new and improved 24nm Toggle Mode NAND is better than previous examples at helping the controller cope with the higher demands placed upon it. This in turn translates into better than expected performance when the drive is crammed full of data.
