Proxy With Separate Disk

[si_faisal]

dear all pfSense and BSD master

hi, let me introduce myself
i'm reza from indonesia

i want to build some router system with HTTP proxy and also traffic shapping
using pfsense, before this, i usually using linux (slackware and Ubuntu).

considering the proxy performance, my plan is installing pfSense to a PC which has 2 harddisk drive,
the first one for pfsense system, and the second disk is to store squid cache file only,

are that possible to do?
anyone has try or sucessfully configure that?

please sharing the knowledge..

sorry if my english is bad. :)

Thanks In Advance

regards
