My first question is when buying an external drive, is it better to get a smaller SSD or go on and buy the larger hard drive that should not have to move around too much.

My second question is how exactly does Time Machine work? In what cases will Time machine not "save" you?

Are you only using this drive as your backup drive? Then go with a larger HHD instead of the SSD. The SSD will be over priced and under capacity for full backups. The only time an SSD makes sense right now is as Ronintexas said, as an internal drive and as your OS and program drive.

Keep in mind with Time Machine that you can also use network drives or drives attached to your router (Airport if your using Apple) for the backup. So the options for backups aren't restricted just the normal USB drives.

The best drives are internal to the computer - the exception to this is when you are moving a lot of files between computers (i.e. work and home) - if they are both at home - you can use the local network....

In my opinion, the best setup is a small SSD (128GB - 250GB) for your operating system and select programs, and a 500GB - 1TB HDD for your data. It is also good to have a 2nd hard drive installed that is large enough to backup both drives - I use a program called SyncBack Free that does this automatically every night.

Time machine makes backups of your system before changes are applied (i.e. installing a program, performing updates, etc), and as long as you have a "good" version saved, backup will take you there. If every snapshot was saved, it would eventually fill up your drives, so only the last 3-5 are saved.
