Most definitely and it varies with the quality and speed of the SD card itself. Typically it is (should be) measured in write/erase cycles and should be at least 100K write/erase cycles. modern SD cards include 'wear levelling' hardware to avoid hot spots that will cause heavily used cells to fail before the overall card. Also, if you have something that writes to the SD card a lot (like system log files, weather software databases...) then you can look to place those files on some other media that is more tolerant of such writing. I have a NAS drive attached to my Raspberry Pi that runs WeeWx for all of the database and HTML files (the log files go to a memory disk and I take the hit of not being able to access them if the system crashes.) If it get 20 or so write tot he SD card a day I'd be surprised but I expect the SD card to last multiple years (about 3 so far). (Of course it is backed up so I can create a new one in a hour or so.)
