I will take a quick stab at this for you, but PLEASE understand that this forum is for discussion of PD9, not a general hardware forum...yes I know...hardware effects performance...but the lines get fuzzy when discussions like this get mixed in with program specific issues. First, yes, Shadow files and Cache files are different, but you should be aware that BOTH are kept on the C: drive.

because PD by default uses C: for cache files.
1. The location of the cache files referred to here are NOT defined by PD9 itself (although most programmers do hard-code this %systemdrive check into the sourcecode). The location of program cache files is determined by the OS. Windows uses the C: drive to create swapfiles and temporary files for running program processes by default. In earlier versions of Windows, the cache files could be pointed to an alternate drive (using the "advanced performance" tab under system properties), but in Windows 7 C: is the default, so even if you set a Paging file on D: (as stated by CL support above), most of the temporary file processing may still be routed to the C: drive. Cache files are hidden by the OS (as are the temporary files created during video production). I caution you AGAINST setting the cache on C: to NONE

considering SSD as my primary drive
2. The consideration between SSD and standard platter media drives is one of
transfer rate and access time. SSD drives have great
access time, so opening static programs is faster. Your Appliications installed on an SSD will always open fast.
They do NOT have great
transfer rates (compared to fast I/O platter media drives) so large files that are re-written and modified
on-the-fly, like the temporary files created during rendering and production (and as stated in #1 above, these are created on C: drive). That is the "rub" using SSD as the main drive on a system doing large and "fluid" file processes.
Finally, The amount of available free space needed on the local C: disk is determined by a formula/calculation based on, and affected by, OS requirements (long stated as a minimum of 20% free) + Program recommendations/requirements (set by each program developer) + CPU count/speed + RAM Memory addressable + GPU cores (and impacted by dedicated video memory and driver version) + SIZE of potential temporary files (based on how big and complicated your productions are).
Add in HD and Bitrate modifications during TransCoding and these temporary files can get quite large!! So the "100GB" recommendation is a "best-guess" that is made based on experience using large files on a STRONG SYSTEM. If you do not have a strong system than all bets are off!!!
Many will tell you that they run the program FINE on a laptop, but be cautious in your expectations, depending on the quality/complexity of your video productions until all the issues with multiple GPUs in laptops is resolved (an issue the CARD and laptop manufacturers are discussing and aware needs addressing).
ATTN Moderator..I hope this doesn't blossom into a hardware discussion you don't want.
