I have a SAMSUNG 840 EVO SSD (120GB) installed on my laptop. According to the SAMSUNG website, it has 520 MB/s max read and 500 MB/s max write (sequential).
I am trying to benchmark it using CrystalDiskMark3.03b as following:
As you can see, the sequential Read/Write speeds doesn't make sense at all. I think even with the fastest SSD drives, it would be almost impossible to achieve 3GB/s read and write as the SATA 6Gb/s interface will limit the speed.
I have checked the specification of benchmarking software and 1MB is indeed 1000,000 bytes.
Am I missing something?

Try another benchmark. I'd trust only a benchmark I've written myself. And even that might lie since you don't know what hardware voodoo happens. I guess you see just cache usage in your benchmark. – qwerty_so – 2015-03-04T14:26:19.863
have you tried to disable the Rapid mode? Are the values now near to what you see in other benchmarks in the Internet? – magicandre1981 – 2015-03-14T08:58:00.823
