Hehe - wait until update time - I had multiple updates about 3 months ago, took over an hour and fifty minutes to download at high speed. The install window came up with the standard, "Several updates have been downloaded and updates may take several minutes..." I didn't finish reading the first three words before the screen went away - it was done.
Should add here though, be diligent about backups - if an SSD dies (rare but happens) all is lost! With an HDD, there was the possibility of data retieval, with SSD - no chance. Backups are your friend - DVD's are cheap.
