The only way to do the same with squid would be to have a dedicated server with like 32Go for it and since you cant afford to loose it, you will have to add another box for redundancy. So in the end, to be able to cache the same amount of info, you will need to add the TCO of 2 servers. And when you think servers tend to have more and more memory and you tend to have more and more servers, memcached makes a lot of sense over a traditional approach of a proxy caching.
