AS SSD Benchmark is a straightforward tool for measuring the speed of your SSD drive.
Simply launch the program, choose your drive, click Start, and it’ll test your SSD’s read and write speed in a variety of ways, delivering a score for each when it’s done. And if that’s not enough, there are also additional file copy and compression-related benchmarks available from the Tools menu. (The author’s support page is German only, but if you need further English explanations then there’s a thread on the program at the OCZ Technology forum.).
The Kingston HyperX Fury 120GB SSD is very comparable to the HyperX 3K 120GB in terms of controller but the Fury is a little behind in read speeds and suffers massively in write speed performance due to uncompressed data AS SSD uses to test each storage device. 4K IOP write speed performance is however very refreshing as it currently sits right behind the 3K drive.
