Today we're testing the PNY Optima 4 GB micro SDHC card, complete with SD adapter. This is a Class 4 memory card advertising write speeds of up to 8 MBps and read speeds of up to 16 MBps. Time to find out whether it lives up to expectations! When writing data, we measured a data transfer speed of 4.7 MBps, which means that the minimum Class 4 speed of 4 MBps minimum is respected. However, this write speed is clearly much lower than the speed announced in the manufacturer's tech specs. At 4.7 MBps, it'll take 14 minutes and 10 seconds to copy a 4 GB file to the card. You therefore can't be in too much of a rush with this memory card! On the other hand, we measured a good read speed of 18.9 MBps. That means it'll take 3 minutes and 30 seconds to unload the same file.
