Testing – HDTune Pro & CrystalDiskMark
HDTune Pro is one of the most popular hard drive software suites available. It has many different benchmarks and tests built into it. Our first test is the read benchmark, which tests the average read speed and access time of the drive.
As you can see SATA 6GB/s is definitely faster than SATA 3GB/s. Now we have the write benchmark.
Our final HDTune test is the file benchmark.
As you can see from the results the Caviar Black did very well topping out at over 175MB/s read and 115MB/s write. CrystalDiskMark is our next test and it has a sequential read / write test as well as a 512k and 4k random read / write test.
