I've been using SD and SDHC cards for over five years now, and in that time I've seen one thing: every single customer who came in with an issue with their card had no concept that their card "failed" for them but did not "fail" for me because they were not using them properly. You'll need a computer that's a little more powerful than a Casio calculator and a normal video card (otherwise, hiccups will occur when transferring data), a card reader that supports at least USB 2.0 (otherwise, data transfers will be sluggish), a USB 2.0 port on the computer that's turned on and has the appropriate drivers installed, and, of course, a card. Lastly, remember that software, especially anti-virus software, can significantly reduce the performance of even a high-quality card when running on a PC with limited resources. You need to be able to use them as medicines, and not stick them without measure and continually in a state of degradation, so I'm not going to even think about brakes in the shape of any "optimizers" of systems, disks, and memory. Furthermore, you can't play videos stored on an SD card, so save your spittle for someone other than Canon. I hope you succeed in your studies. The MANs to your helpful gadgets!
