Looking at our third benchmark, Crystal Disk Mark 3.0, we can see the similarities once again between the Silicon Power Jewel J80 32GB and the Mobile X31 32GB. Numbers across the board are very close, with the exception of the 4K QD32 test. For sequential write and read speeds, we get 23.4MB/s and 120.6MB/s, which are once again among the slowest of USB 3.0 drives. In fact, the OCZ Rally2 Turbo 4GB, a USB 2.0 flash drive, achieves a slightly higher sequential write speed compared to the Jewel J80. The 512K write and read results follow the same trend we have seen so far from the Silicon Power Jewel J80 32GB. As for the 4K and 4KQD32 tests, this demands high input/output operations per second (More commonly known as IOPS). This is probably more surprising than anything, as the Jewel J80 actually pulls out one of the highest read speeds in both of these categories, far outshining drives like the Kingston DataTraveler Vault Privacy 3.0 32GB and the Patriot Supersonic Magnum 64GB. I am astonished to see such a reverse in numbers, especially when all the other results are not that high.
