CrystalDiskMark Performance

CrystalDiskMark is a synthetic benchmark we've started looking at 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 large sequential transfers and worse case being small, random 4K transfers.

Synthetic File Transfer Tests

OCZ Vertex LE - 100GB MLC SSD

Fusion-io - 80GB MLC PCI Express SSD



The OCZ IBIS drive performed a little bit like it did in our previous SANDRA testing, offering higher write bandwidth over all sequential tests and with larger 512K transfers, but about 10% behind the ioXtreme with respect to read requests.  Also note that small file random reads and writes are only about on par with a standard single SSD, but as queue depth is increased the IBIS drive extends a significant lead, doubling the ioXtreme's read performance and matching it in writes. 

We'll take a look at one more synthetic test setup and then some real work numbers, on the pages ahead.
