Windows 7: Minimum free space on hard drive?

YES

The performance characteristics of an SSD are an almost perfect match for the typical usage patterns of the pagefile. On the other hand, the characteristics of a conventional drive could hardly be more wrong. Pagefile usage typically consists of small reads scattered over the pagefile and mixed with reads from other files. On a conventional drive that means a lot of head seeks. Conventional drives have good transfer rate (but not as good as an SSD) but that matters little because far more time is taken reaching the data than reading it. Since SSDs have no moving parts seek time is almost zero and these problems do not happen. There are few files that benefit more from an SSD than the pagefile.

Certainly, SSDs do have limited writes. But in modern drives that number is so high that it is difficult to reach under real world conditions. SSDs can be killed with excessive writes but you really have to work at it. Having the pagefile on an SSD isn't going to do it. Typically an SSD dies from other causes long before writes become a factor. Or more likely the drive is replaced because it is just too small.

The only legitimate reason to put the pagefile on a conventional drive is as a temporary measure to conserve space on the SSD.

You are also continuing the routine of making full images of your OS and Data partitions onto external media?

You are both right. My practices are somewhat out-of-context as I usually do not even need a pagefile. And by far the fastest memory to use is your RAM. I generally load up RAM and rarely use any pagefile at all, some systems, none. But these are specific scenarios and this kinda breaks from atikovi's topic a bit.

What constitutes a "modern" SSD is a question I have not heard an answer from though?

That is a good beginning but it's only a bit less than 10%. You really need maintain at least 98-123GB free space.

The hard-drive and Windows act like a house, even though external square footage may quite large, the inside, livable, square footage is going to be somewhat less. Infrastucture.

Here is how I recovered over 100g of my 250g SSD space using the WIN 7's built in utilities:

SYSTEM RESTORE
Do you have System Restore (SR) enabled on this SSD drive? If so you may have an unnecessarily large amount of the drive allocated to SR files. This can be checked at: Control Panel>System>System Protection. If your C drive shows its "On", highlight it and click "Configure". A window will open to show both your Current Usage and Max Usage. You can reduce Max Usage with the slider to a smaller amount (maybe 10%) to eliminate older SR files. This can salvage a ton of space (depending on your current setting perhaps in excess of 100 gig).

WINDOWS UPDATES
You can also regain up to 8 gig of space by letting Windows delete redundant WIN Update files that it stores even after they have already been installed. In My Computer right click on your C drive and select Properties. Click on Disk Clean Up. In window that opens click "Clean up system Files". This will prompt you through cleaning up the redundant WIN Update files. While there you can also choose to delete other files like Temp files, but they are miniscule in relation to the System Files which requires you click that separate button to delete.

Edit: If you do clean up your WIN Update files, when you reboot it will give you a message to not turn off your computer because WIN is "Reconfiguring Updates." There is a progress bar that will pretty quickly show 100% complete but it will still be running. Let it complete the reboot by itself (don't rely on the 100%) It may take longer (mine took quit awhile . . . maybe nearly 1 hour) to complete. It completed and I've got my space back.

Hard Drive Free Space
I know that it is necessary to keep ~15% free space on the system drive for proper function, but what about a non-OS drive that is used only for storage? My video archive drive never seems to get fragged, so I doubt that I will need freespace for defragging...any other reason to need it?
