Types of memory
There are numerous types of memory cards in use today, the
most used memory cards today are the SD (Secure Digital)
range of cards but even these can be really confusing to
choose when they are not something you purchase regularly,
if the device you need the card for is old or second hand
without the original manufactures instruction sheet and
specification it is possible to become easily confused.
The safest method to purchase a card is to try before you
buy, unfortunately as most well known makes of card are supplied in
sealed retail packaging most shops are reluctant to allow
this, also as the best prices are now normally achieved by
online purchase this option is not possible and once the
sealed packaging has been opened return can be problematic.
Let's look at some common examples.
