Access Time, I/O Performance
Access time isn’t really an issue for memory cards that are used in digital cameras, but still there are differences.
The IOmeter performance results are mostly interesting if you intend to use an SDHC memory card to run an operating system or applications, in a small form factor environment where even small hard drives would be too large. Cards capable of processing a large amount of I/O operations per second will do the best job when it comes to frequently changing access types or simultaneous read/write operations. Lexar’s Professional and the Transcend 150X are best in this category.
