How many memory cards do you need? It depends on several things:

- sensor size (a 10 Mpix camera creates bigger image files than one with 3.2 Mpix)

- file format (usually J

According to USFDA, a combination product is one composed of any combination of a drug and device; biological product and device; drug and biological product

PEG is relatively compact, but when you prefer RAW, prepare to pay out much more money for extra cards)

But memory cards are not just about capacity. The next parameter that should concern you is speed.

As a rule you need extra-fast cards:
