Anandtech tested the caching with the Intel 311 20GB and a Corsair Force 40GB and the differences between the total cache space showed. The MLC did not cripple the Corsair very badly, however... I think I may have to buy my wife a z68 SB based system and use the x25e 64GB I have in her current s1366 desktop. I've been waiting to upgrade her to SB when z68 came out. Wonder how this will fair as a cache. 😀
