STEADY STATE 4K RANDOM WRITE IOPS TESTING
The bread and butter of OCZ SSDs it seems these days is their fine tuning of both the Vector and Vertex at a level above what we might see in many consumer SSDs. By listing specifications that speak to steady state testing, and even then speaking of mixed load testing that we see in enterprise SSDs, OCZ literally dares reviewers to rip their drive apart and write about it. The result is just under 14 hours of testing, the majority of which is low 4K incompressible data testing by which any questionable drive would definitely show its colors.
For our own testing, we have stood the OCZ Vertex 460, not only beside the enterprise Seagate 600 Pro and consumer Plextor M5M Extreme but also, we have included the previously released Vector 150 to show how similar these SSDs really are:
As you can see, the OCZ stood well above its consumer counterpart, yet just below the enterprise SSD as expected. Most interesting however, is how close it is to the previously reviewed OCZ Vector 150 SSD. It almost seems that, even with the new and improved Indy Barefoot 3 M10, they beefed performance up just a bit as we originally saw steady state IOPS just above 21K for the Vector, and we now see the same steady state IOPS just above the 22K mark for the Vertex 460.
MIXED WORKLOAD PERFORMANCE
Up next in our test file we decided to put OCZ’ claims to the test with a bit of mixed workload testing. Once again using IOMeter, we tested all three SSDs with data samples typically seen in a Database (67%R/33%W), File Server (80%R/20%W), WorkStation (20%R/80%W), and a Web Server (100%R). These tests were conducted part and parcel to steady state testing above.
This mixed workload testing was conducted just after steady state testing, and even so, still had a ‘ramp up’ period for mixed workload testing. As we can see, the Vertex 460 stands its own ground beside the enterprise Seagate 600 Pro, and once again, is remarkably similar to the Vector 150.
MIXED LOAD PERFORMANCE – SECURE ERASE
We were a bit curious as to what the mixed load comparisons would look like after we did a secure erase on the four SSDs. We were very confident that a performance increase would be seen, however, wanted to se if the comparisons deviated at all, especially since the configuration file accounted for a ramp up period before conducting the test.
Secure erasing the Vertex 150 fared particularly well, especially in Database and Workstation comparisons where it topped all other drives.
