I normally setup my pfSense using 2 SSD HDD and in a mirror the 2 disks.
Yesterday, my supplier offered me a box that has 1x 30GB mSATA and 1x 120 SSD…
assuming I would install pfSense on the smaller, 30gb mSATA, what will you do the second disk if it isn’t in mirror configuration?
Back when I first started with pfSense, I thought the same thing, caching updates would be nice. Then I tried to make it work properly with everything… I promptly cut up, battered and deep fried that squid.
But feel free to install it and see if it’ll work for you!
