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.
The Intel SSD 730 put up some very strong numbers in all of the various CrystalDiskMark tests. It led the pack in the 4K and 512K transfer tests and remained competitive in the others as well. And with the exception of the 4K transfer test, the RAID 0 scores were in a class of their own.
