Benchmark: Crystal Disk Mark
The CrystalDiskMark test uses incompressible data, and it's a benchmark that SandForce-based drives have a tendency to struggle with.
Crucial's Marvel-powered M4 SSD coped well with a bombardment of small files at a high queue depth, and Corsair's Performance Pro goes one better. With a larger cache, Toggle Mode NAND and updated firmware, it returns the best results we've ever seen from a 2.5in drive.
