Results: ATTO, HDTune, CrystalDiskMark
ATTO is universally used by SSD manufacturers to show what the drives maximum read/write capabilities are under ideal circumstances. The bandwidth results here are not necessarily entirely reliable for reporting the maximum drive speeds, but it does help convey results of the bandwidth for different file sizes.
Let’s see what happens:
The 524MB/s and 498MB/s Read/Write speeds are a bit slower than what we would typically expect to see in a SandForce 2281-based drive, though not too far off the pace.
HDTune Pro offers a robust set of benchmark tests for maximum, minimum, and average transfer rates, and in this case we’re focusing on the read results for this test. Again, there are minor variances with SSDs when using HDTune, so don’t treat these results as absolute and unchanging, but they do paint a good picture of what’s happening with this SSD.
Again we see the Read and Write results a bit lower than what VisionTek claims, though we typically see some variance in testing results amongst the different benchmark applications.
Crystal Disk Mark
Crystal Disk Mark is a lightweight benchmark that has two parameters, Sequential and Random read/write, to evaluate the performance of a drive. Crystal Disk Mark’s default test uses random data and the writes in particular can be very punishing on SSDs.
Let’s take a look at the speeds.
The Sequential results are similar to the other results, just a bit higher than VisionTek’s specifications, while the 4K Q32 results are particularly encouraging, showing excellent scores.
Let’s check out a couple more difficult tests next.
