Our tests of SD and MMC memory cards showed that in case of Kingston Elite Pro Secure Digital card SD/256-SCS the user gets a solution that performs almost as fast as it is supposed to, according to the claimed manufacturer’s specifications. If you go for Kingston Standard Secure Digital Card SD/512, you will get a notably faster device than the manufacturer promises you on their site. The third SD memory card, the one from RiDATA, failed to reach the claimed 66x performance level in the FC-Test, although it came real close to this point.
As for the fourth solution participating in our today’s test session, the Kingston Reduced-Size MultiMediaCard MMCRS/256, it failed to meet the specified speed rates. The 2MB/s speed hasn’t been reached in any of the tests. I assume that the last solution is a way too slow for the today’s user requirements. Although, I have to admit that we will only be more objective when we compare its performance with that of other MMC devices. We will do this in the nearest future, and in the meanwhile you might just take our results into account while shopping around for removable memory storage.
