Does pfsense run solely in ram when fully booted?



  • I have just recently started using pfsense with my microserver g8 using 1265L and 16GB ram with an old hdd as a boot drive.

    What I would like to know if pfsense runs solely from ram after fully booting, or does it still use the hard drive?
    Please fill me in on how it works. For instance if some packages prefer storage over ram, etc.

    Also, should I migrate to using an SSD instead of HDD as a boot drive?

    I am currently only using Squid and OpenVPN on a 50/50 broadband with no significant loss in bandwidth or increase in latency (3-4ms).
    I know the system specs might be a bit overkill right now, but i want it to be ready for 500/500 or gigabit later on.

    I am also new to the forums here, so please tell me if im doing anything wrong.  ;)



  • I don't think pfsense is designed to run ram-bound but maybe a Mod will have a better answer.

    SSD/HD as boot… (1)why u not happy with current boot speed? (2)Other than generally solid state more desirable than mechanical drive, I feel performance diff not hugely significant. (3)Am running on a usd$10 16G SSD using only 10%, what is ur current storage usage?

    (1) I dont feel unsatisfied with the current boot speed as i rarely reboot it.
    (2) I see your point here, but i think it would be better to use an ssd because of a lower failure risk in that situation. Could you link me to the store you bought your ssd from? ebay?
    (3) The system reports 0% out of 447GiB so it is using less than 4.47 GiB



  • I eBay my SSD and splurged on a used 16G Sandisk for usd$7.  S.M.A.R.T. says is been used for less than 2 days.  Am happy.  Even if u buy new, a 16G SSD shouldn't be that much and you will still be using 1/4 of its storage.  Not a big decision.
