Performance with MMC Cards

Intel IOMeter Sequential Read and Write

I guess the diagrams make it clear which controllers support the new standard and which of them work in the compatibility mode only. The AU6362 (with firmware 01.26 and 01.29), IC1210, ND3260 and SanDisk USB are in the slow group. As opposed to the previous tests, the controllers from the fast group don’t have similar graphs. The GL819 with firmware 93.21 is the best on large data blocks (by the way, it is the worst in the fast group with firmware 93.17). The AU6332 outperforms it on small data blocks, though. The AU6333 has a highs speed as well, but slows down heavily on 16KB blocks.

We’ve got the same five slow controllers again. It’s hard to find the winner because the fast controllers have similar results. The AU6332 differs with its fastest growth of speed along with the data block size. The AU6333 is suddenly slow on 1024KB data blocks.
