Performance

After digging into the Vector 180 and finding out a little more about what’s inside I put it all back together and ran it through our recently updated SSD benchmark suite. Our testing consisted of 27 different benchmarks across a range of tests to see how the Vector 180 480GB would perform in synthetic and real world situations. To start things off I ran the Vector 180 through CrystalDiskMark to get a look at its sequential read and write speeds. Ignoring the two PCIe based drives we can see that the Vector 180 came in a little lower than I would have expected on the read side of things. It was actually lower than the Vector 150 even. On the write speeds the Vector 180 pulled ahead a little more though, performing just under the new S10 based drives.

For my next test I ran through the three copy benchmarks in AS SSD, here we are looking at total time it takes to do the tests. As far as SATA based drives go the Vector 180 came out near the top with just the Striker and the Force Series LX performing better as a whole.

Next I ran through the advanced disk benchmark tests in Passmark, specifically the tests that show what to expect in performance in a few different business situations. The results were interesting. When the results are combined it performed slower than the older OCZ drives and a little below the S10 based drives but individually the File Server results were by far the best we have seen for a SATA drive.

For a more real world benchmark I use the new PCMark 8 storage benchmark. They run through multiple real world programs like office and even WoW for gaming. Rather than use the score that PCMark 8 provides I actually prefer to look at the overall average storage bandwidth from across the entire test. Here we can see that in real world situations the Vector 180 is actually noticeably faster than the other SATA drives. Hell it is getting close to the performance you would see from the M.2 based Predator as well!

To check out the IOPS performance of the Vector 180 I run through the SSD benchmark from Anvil’s Storage Utilities and use both the read and write results from the 4K test at a queue depth of 16. Much like a lot of the other drives, the Vector 180 actually performed noticeably faster on the write performance in this benchmark. In fact for the write speeds it was one of the fastest SATA drives tested. N the read side of things the numbers were a little lower than I would prefer and overall when combined the total numbers are a touch less than the S10 based drives that a lot of the other manufactures are using.

To look into the results more from the Anvil test and also to see how well the Vector 180 can handle different queue depths I tested the drive in a range of queue depths in Anvil’s Storage Utilities at 4k both on the read and write sides. While the Intel 750 Series nearly makes this graph impossible to read, if we look close we can see that on the read performance the Vector 180 was slow to ramp up compared to the S10 drives but at high queue depths it was actually at the top of the charts for a SATA drive. For write performance it was a little different. At a queue depth of 1 the drive is actually much faster than everything else, including the M.2 Predator. It performed better while ramping up, fell off at a queue depth of 32 and then out performed at a queue depth of 64. The Vector 180’s peak performance wasn’t the highest, but it performed the best overall across the board other than that.

Happy Friday everyone. Today I take a look at the latest SSD from OCZ. Enjoy
