CrystalDiskMark is an easy-to-run and quick utility to use to gauge a drive’s performance. It measures sequential read and write performance and random read and write speeds of random 4KB, 4KB (queue depth 32) and 512KB data.
Overall, the Vertex 450 performed admirably amongst this collection of very high-end SSDs. Sequential read and write speeds were amongst the best, but we noticed that read performance on the 4k and 4k, queue depth 32 workloads suffered a little. Unsurprisingly, the Vector was comfortably faster than it in all instances, though the margin wasn’t great.
