I have successfully implemented Intel RST, with a 64Gb SSD. However the application screen is showing I am only using 19Gb of the SSD, with a further 41Gb showing as a Data volume. This in turn is shown as unallocated in Windows 7 disk Management. How do I change the cache size to use all the available space on the SSD
 
The Intel Rapid Storage Technology (IRST) driver presumably enhances the performance of a HDD/SSD. Many users find no difference in the performance of their drive(s) whether IRST is installed or not. Others find a slight improvement. In any event, IRST has NOTHING to do with disk capacity, so it's not clear why you're mentioning it in the context of your query.

I believe the actual capacity of your 64 GB SSD is somewhere around 60 GB. Apparently you've created a 19 GB partition (I suppose it contains your OS). The remaining unallocated disk space is 41 GB, so it appears that the system is reporting the full capacity of your 64 GB SSD. Naturally you can create a partition out of that unallocated disk space and use it for any purpose you desire.

Please understand disk space capacity has nothing to do with a drive's "cache". You might want to Google "disk cache" for a thorough explanation of what that is.

i think rst's minimum size is 18.6 so looks like its set to use the minimum. i would suggest taking rst off, then deleting any partitions on the drive and then turning rst back on but this time look for a size setting when you pick the drive you want
