CrystalDiskMark Testing

CrystalDiskMark is a synthetic benchmark that tests both sequential and random small and mid-sized file transfers using incompressible data. It provides a quick look at best and worst case scenarios with regard to SSD performance, best case being larger sequential transfers and worse case being small, random transfers, especially random write requests.

First, careful with the chart sorts here, as they switch around a bit. Blue bars are always read metrics and yellow is for writes. Crystal shows some different angles with respect to performance characteristics of each Solid State Drive we tested. The sequential test shows traditional drive throughput with read performance generally coming in faster than writes. Here the SSD 750 was neck-and-neck with Intel's P3700 enterprise-class product, blowing past the OCZ drive in the process.

For writes, none of the drives could come within striking distance of the Intel P3700 but the SSD 750 was at least in the neighborhood. Regardless, if you look at our previous ATTO scores, the SSD 750 lives up to its claimed throughput specs and then some in most cases. However, with CrystalDiskMark things appear to be more strenuous for all drives tested and the SSD 750's top end read performance isn't realized in the longer, sustained Sequential tests. However, in small file transfers and with deeper queue depths for the 4K Q32 test, nothing comes close to the pack of Intel drives we tested, even the legacy SSD 910 drive. In fact, the SSD 750 looks like a pro in these common end-user workload transfer sizes, even nipping at the heels of Intel's big iron P3700.
