CrystalDiskMark is a synthetic benchmark that tests both sequential as well as random small and large file transfers. It does a nice job of providing 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 access and transfers.
CrystalDiskMark does a really nice job of exploiting the strengths and weaknesses of Intel's new PCIe SSD solution. On top, we see the drive's pure sequential performance competes with the likes of OCZ's Z-Drive R4, even edging it out in overall write throughput. However, drop that files size down to 512K and read throughput takes a nosedive, though still fairly robust with write throughput unaffected. Drop down to a tiny 4K transfer with a shallow queue depth and the Intel SSD 910 takes a knee. Conversely however, scale up to a queue depth of 32 with that same 4K transfer payload and Intel's SSD 910 earns top marks. It's here that we begin to see just how this new PCI Express solution from Intel is tuned. In short, when all SSD controller resources on the drive are exercised, the SSD 910 will stretch its legs. A client-tuned SSD this product surely is not. The SSD 910 appears to be tuned for big iron workloads and access patterns.
