CrystalDiskMark is a small HDD benchmark utility for your hard drive that enables you to rapidly measure sequential and random read/write speeds.
For comparison, I ran the same benchmark on both drives to see if there was any large difference in the results. First, the Apex:
Secondly, the Titan below. As you can see, the drives performed nearly identically given a small variance that occurs with every test. Additionally, you can see that the sequential read and write speeds are right at the levels OCZ lists in their specifications.
