What a great question and even better set of testing. Folks that have been following flash storage speeds, capacities and implementations likely already know the answer to this one, but mainstream consumers or those new to mobile tech will really appreciate Jerry Jackson’s efforts. He’s a got an excellent set of tests to compare SDHC cards, traditional hard drives and Solid State Disks. After all, flash memory is flash memory, right? Not so since there are different speed classes and interface capabilities.The long and short of it: with a fast card reader in your mobile device, an SDHC card offers good value, i.e.: expanded storage capacity that can be accessed quickly, but not written to or read from nearly as fast as a much more expensive SSD drive. Well worth the read for a better understanding of this technology especially since SSD drives are still not cost-effective for widespread adoption. This could really come into play if more manufacturers go with the low-cost, low storage capacity model like the 2-, 4- and 8 GB Asus Eee PCs. Having an SDHC card reader there can go a long way to complement storage in the cloud of the web.
