There is a lot of misunderstanding about caching. Intel developed caching for clients and businesses that could not afford a large capacity ssd. A few years ago when the concept was on the drawing board, Intel hoped clients and businesses would purchase a small 10Gb or 20GB ssd like their M11 for about $100.00. Microsoft Windows 7 and all software applications would remain on hard disk drives. The cache only produced a minor boost in performance. Intel hoped that once clients saw the slight performance boost they might be inclined to purchase a larger capacity ssd to get a larger boost in performance
Intel also researched the size of the cache. Intel determined that a 60GB ssd was the point where it made no sense to use the ssd as a cache for a hard drive. Instead if you have a 60GB ssd, then Windows 7 and software applications should be installed on the ssd to take full advantage of the ssd capabilities.
Prices for ssd's have changed. $100.00 will get you a lot more than a 10GB or 20GB ssd. Since you have a 60GB ssd it makes more sense to install Windows 7 and your software applications on an ssd. The ssd performance boost is much higher than the hard disk drive performance increase.
Windows 7 Pro 64 plus all the updates will use up a just a little over 20GB leaving plenty of room for software applications and a few games. Data files are stored on the hard disk drive.
