CrystalDiskMark Benchmark Results

Website: CrystalDiskMark

CrystalDiskMark is similar to AS SSD in its use of incompressible data files, although it does use a different data pattern. We report the read and write results of the sequential and 4KB random tests

SSD's are starting to hit a wall now, performance is creeping up rather than jumping.

Wonder when/if we'll start seeing more significant gains anytime soon or an increase of life? 40GB per day is easy to use if it's used for a DB, cache, etc.

Sata Express is coming soon* which will remove some of the current performance limitations.

*whenever Intel gets around to launching new cpus / chipsets with it.

But until then the price war going on between the M500 and the 840 Evo just renders all other consumer ssds pointless, just my 2 cents.

They're not the only ones offering largish capacities at increasingly cheaper price points, there's at least 2 others now (who are also major nand fabs like samsung & micron) who are starting to do the same, but with SSD's that have markedly better perf. or reliability characteristics all-up. Sandisk (Extreme II) being just one of them...
