SanDisk Extreme SSD uses SF-2281 controller and 24 nm flash memory made by SanDisk. We have never a seen a combination like that before, so it is particularly interesting to check it out and see if contemporary Toggle Mode NAND will be able to breathe new life into the second-generation SandForce based platform.

We use AS SSD version 1.6.4237.30508 test to benchmark the speed of copying files within a single partition the size of the whole SSD. The SSDs are tested in their steady state.
We don’t see anything new in the copying tests. SandForce-based SSDs aren’t fast at copying files due to their relatively low write speed. The SanDisk with its suboptimal TRIM implementation is far from impressive, too. We must note, however, that the AS SSD benchmark uses files with incompressible data. We’d have different standings if the controller had the opportunity to compress data written into flash memory.
