The IBM Microdrive 1GB really it all: built in Compact Flash II format, it offers plenty of space for any digital camera that supports CFII. It is small, quiet and fast. On my Canon PowerShot S45 fit 512 pictures in the highest quality on the Microdrive in 640x480 resolution, there are nearly 4000. With lower quality, the image quantity increases to about 1000 shots at full resolution. The Drive is therefore a really worthwhile investment for those who take a lot or go on vacation. Interruptions or errors I had previously recorded no because the Microdrive smaller Rempler not mind.
