I think it comes down to the apps you're running. I've only been doing it for a day, but I just installed the PortableApps.com suite to my SDHC card (with some other programs added on) and most of the programs are pretty snappy (they're designed to run quickly from removable flash storage). With a bit of searching, you can get just about any type (if not exact title) of software you need on your system and be able to save a lot of SSD
space in the process.
I'm actually a fan of using PortableApps even on my home computer, since everything is contained in one folder, if I need to move something or I have a serious crash, I just move one folder and all the settings and data go with it, even to other computers.
As for personal files and documents, I plan to use Dropbox
to keep my currently relevant documents up to date across all my systems, and a home VPN (Probably with Hamachi
since the XP VPN doesn't feel...complete) to access the other 200GB of files (not including music or videos) that I can't store on my mini, no matter where I am, as long as there's an internet connection. I'll probably use rsync to back up my Mini9 on a nightly basis, since I have plenty of space for a backup copy of all my Mini's data (I just used DeltaCopy
instead of setting up Cygwin manually). If you need more security, don't save your VPN password, and use TrueCrypt
to create a virtual encrypted drive (EncryptOnClick is great for individual files and folders).
My vote? Get a nice big and fast SSD
for very large files or big programs, and toss in a 16GB SDHC card for all your documents/music/videos and very small apps. Be selective about what you store on the SDHC but set up a VPN/SSH/SFTP connection to get to the stuff that doesn't need to be on there full time.
