What can you do with a Linode 1GB?

I started out with a Linode512 for $20 which is now a Linode 2GB, still for $20.

I use it as a LEMP for several personal sites including Wordpress blogs (optimized, W3 Total Cache). Total number of visitors per month is less than 10,000.

Even if I add a couple of sites and the number of visitors triples, quadruples or even increases tenfold that should be no problem whatsoever.

• Question 1: A Linode 1GB LEMP, properly configured, should be able to handle up to a 100,000 visitors per month, right?

Because that is what I have in mind: downgrade my LEMP from a Linode 2GB to a Linode 1 GB. And use the $10 saved for an extra Linode 1GB for setting up an owncloud server, maybe in combination with a svn or git server.

• Question 2: For personal use that should suffice I think (except for storage space)?

• Question 3: Due to lack of time I haven't upgraded to SSD yet, (so I cannot see the information) but can you still buy extra storage?

Thanx.
