Best SSD for Caching

Hi all,I'm building a new rig and plan on using an SRT setup for hard drive caching. Trying to figure out which SSD I should go with to give me the best performance.Should I go with the Intel 311 Series 20GB? This one was developed by Intel specifically for use with SRT, and is one of the few that uses SLC NAND memory (which is supposed to be faster and longer-lasting than the MLC NAND used by most SSDs). However, I don't even see this drive listed on Newegg anymore (although it is on Amazon and elsewhere), and a larger-capacity drive (say, 40 or 60GB) would result in fewer files being booted out of the cache after non-use, correct? Cheers,Scott
