Since only 1.6% of Backblaze customers have 2GB or less of RAM, the other 98.4% desperately need 64-bit support, period, end of story. The main gigantic upside of a 64-bit process is the ability to support more than 2GB of RAM. In other words, there is zero downside (and there are gigantic upsides). Moving over to a 64-bit OS allows your laptop to run BOTH the old compatible 32-bit processes and also the new 64-bit processes. ![]() There are a few absolutes in life-death, taxes, and that a 64-bit OS is better than a 32-bit OS.
