There are many formats of memory/harddrive you can use to play video or show files from on micro projectors. These range from the Micro SD Card to the SD Card, in our experience with micro sd projectors so far we would say that when it comes down to it all solid state media are pretty similar in response time, loading and quality. The great thing about micro sd is the size – a minute memory stick/card can fit anywhere – its smaller than a postal stamp yet you can get them in some high capacity, high quality models.

High capacity Micro SD cards are a great idea for micro projectors, their only downside is their size. We found some great 8gb micro sd cards which should be ample to store any film in up to dvd quality (4.4gb) – they arent quite at the blu ray quality sizes yet (24gb+) but then the micro sd projector’s they would power wouldnt be able to do the hd/blu ray resolutions anyway so for now 8gb should suffice you. Most of the micro projectors hailed as multimedia microprojectors should handle micro-sd cards and so come under the micro sd projector bracket, if they only take regular sd cards, then as with a lot of other devices you can always use the sd->micro sd adapter you often get with the card itself.
