C: SSD, D: HDD 5400 - works well but what with the media catch files??

Question

Hello there, I'd like to ask a question:
I do not have a lot of money to spend, so I'm not really enthusiastic about buying new hardware. I just bought a new SSD - Samsung 840 Pro 128GB (C: drive) and installed beside Win7 64bit, the CS6 Premiere Pro. By that I have a WD 1,5TB 5400 harddisk (D: drive). I know you recomend a 7200 disk, but as for the money situation, I just wanted to try it. Everything worked fine at first glance, but then I searched the internet and came to Harm Millaards discussion about the Media Catch Files - as it's no good idea to put them on the SSD disk. This was standard in preferences set to the C: SSD, so I switched them to my D: drive instead of the C:. The same I did about the Scratch disks/files (don't actually know what they are though :-/). Is this correct?
After the change of the Media Catch files to D: the playback while editing is not quite well working anymore. Did I do they right steps and does this then mean I should buy a HDD 7200 for the media catch files and as a scratch disk (which I don't understand what it is)? Will that help, or should I do something else to have it working as it was working when these files were saved on the SSD?  
Thanks a lot for your help, Thomas
PS. other hardware I have:
8GB RAM
intel i5 2500K procesor
Geforce 295

The pagefile is a dedicated file created and managed by Windows. It has no relation with PR. Windows uses it as a virtual memory file to store data that don't fit in the physical memory of your system. The lower your physical memory, the more Windows uses the pagefile. It is somewhat similar to growing older and you need to remind more stuff, but you tend to forget, so you write it down.  On all systems I suggest to use a static pagefile, on that has minimum size and maximum size the same dimensions, so for instance a fixed size of 32 GB. If you do not make it static, but let Windows manage the size, as is default, you can get fragmentation of this file and it requires - on each change of size by Windows - new writes to the FAT, which reduces the lifespan of your SSD.
Your setup is exactly what my analogy alluded to. You are right.
