About 6 weeks for an micro SD card or USB memory stick with a Pi
being used as a timelapse camera taking a full HD image every 30
seconds, checking the overall level (no point in storing black images
during the night), adding a time/date caption, generating a thumbnail
and compiling the previous 24 hours into a 2 minute (ish) timelapse
movie every 3 hours. The initial photo produced 2880 1 M byte (ish)
file writes/day, adding the caption another 2000 to 840 depending on
the season. An 8 GB card/stick was pretty full holding about 3 days
of still images, the movies and have enough working space. A single
day would have about 6 or 7 GB of writes done. With not much elbow
room for the wear leveling to work with, unlike a card with a fair
bit of free space.
