64GB means it holds 64 Gigabits of information, depending on what resolution you set for the camera... that's a lot of images, 2000? roughly, my guess at the resolution you shoot at.

95MB means up to a speed of 95MegaBytes per second of read speed, and possibly up to 90 of MegaBytes of Write speed. Usually that's good enough for video speeds, and more than enough for bursts of continuous shoot stills.
