SanDisk are one of the most well known manufacturers of flash memory cards, if not the most popular of all. In recent times, memory cards have decreased drastically in price and can be found for bargain prices, this one can be found for around a tenner. With the M2, they keep getting better, as it is a tiny 'micro' SD card which is about a quarter of the size of the standard memory cards (11mm in height, 15mm in width). Since it is so incredibly small, it requires an included official black adapter which is the size of an ordinary SD card (32mm in height, 24mm in width) and slots into it easily. There is also a thin metal sheet to keep the small card safe and sound when inside the adapter. It boasts an impressive 8 Gigabyte capacity, capable of storing a vast amount of data. Although it depends on resolution, size and file type, it can store anywhere between 750 and 2000 high quality photographs and / or songs. HD video is also an option but take up a larger amount of space - 8GB will get you anywhere over 1 perhaps 2 hours of footage, again depending on frame-rate etc. Mine has never had any problems displaying or storing photographs, speed or quality wise, in my Canon E500 digital camera, nor has it suffered any ill effects inside my Playstation Portable (PSP) which it now resides, holding all my favourite classic PS one games. Of course if you are going to read it, you'll either need a) an SD card reader or b) the easiest option, leave it in your camera, phone, psp whatever and simply plug in the device with the appropriate USB cable.
There are larger memory cards out there though, so you may want to consider looking some up on all the standard big brand websites and stores, as there are some that go above and beyond the term 'adequate storage' with 16 and even a whopping 32GB. It just depends whether you are often on the computer to store your photos (if so go for this) or are on a journey around the world (go higher).
