Samsung 830 SATA3 SSD 256GB Review
Crystal Disk Mark
In 512K and 4K read testing the 830 isn't quite up there with either the Sandforce equipped Hyper X or even the Micron controller of the Crucial M4. However the straight sequential test has it right up there at the top of the graph and in QD32 testing it's on a par with the Hyper X.
It's a bit of a double-edged sword in the Crystal Disk Mark write tests. At the 4K end of the scale the Samsung 830 is definitely the slowest of the three SATA6Gbp/s drives on show, yet when it comes to large chunks of data it leaps to the top, giving some excellent write speeds.
