I think you meant your hidden partition is 100 MB not GB. I successfully ran Window 7 off of a 60 GB SSD - the trick is to move all non-essential folders off the SSD - stuff like My Documents, My Pictures, etc. With my setup, I have my new 180 GB SSD (Intel Cherryville 520 SATA III) as my OS drive, my older 80 GB (Intel X25-M G2 SATA 2) set up for all of my profiles, and dual 1 TB (Seagate Barracuda 7200.12) drives for storage. Even before my incorporation of SSDs, I always kept data separate from my OS drive, so in Windows 7 I would always move the 'special' folders from the default location to another mechanical drive. When I got the 80 GB SSD a few years back, I revamped the installation. I used Profile Relocator to relocate the entire user tree over to one of the mechanical drives, to save space on the 80 GB. When I bought the 180 GB drive a couple of months ago, I revamped it again. I installed Win7, used ProfileRelocator to move the user tree to the old 80 GB drive, and set up the page file on both SSDs only. I then again manually moved the special folders to the mechanical drives to have ready access to all of my documents, photos, videos, etc. Now, all of the cache related stuff is on the 80 GB drive, the main OS files and all programs on the 180, and all data on either of the 1 TB drives. (I've actually toyed with combining the 2 TB drives into a RAID, since I really don't want to lose my data, and neither drive is more than 25% full, but have not found the time to incorporate the idea yet). That's about right. I have 12 GB of RAM, but I made my pagefile 12 GB on both SSDs, just to stagger it a bit.
