Small ssd disc?



  • im thinking of order this small ssd for my pfsense router, today i have a 2.5 ordinary sata disk, but the problem is that it gets hot, it never goes to sleep, so im thinking of an cheap ssd instead, this one is only 8gb large, but i guess that it would be enough? i dont istall anything other that pfsense onto it.

  • The only reason to go to a larger SSD is that the built-in SSD wear leveling firmware would have more empty space to work with with a bigger drive. I picked up an inexpensive 64 GB drive and have been using it with no problems. Looking at what is being used 8 GB would have a fair amount of free space.

    Just use a 8-16GB USB Flash drive.



  • Why would you need an 8-16gig pen drive or such a large ssd anyhow ?

    I have yet to install pfsense but Its only like 250meg the memstick version,  or does it use up that much space ?!

    Depends on what you are doing with it… I had a kingspec 16GB that I killed pretty quickly by running dansguardian and squid.



  • I'm far from an expert on this, I read enough to see what would work for me, quit reading and went with it so take this with a grain of salt.

    With an SSD things work as expected with a full install of pfSense, you won't burn out a decent sized one that has free space for wear leveling very quickly. With a CF or thumb drive it seems you need to use one of the limited versions of pfSense or do some serious tweaking to the full version to keep from killing the storage.



  • I'm using that exact KingSpec SSD 8 GB on my Pfsense box at the moment. Been running it for about 2-2.5 years with no problems. This kind of SSD is perfect for Pfsense imo.



  • ok, i have ordered the ssd disk, i hope it will work good, is it just to restore the setting after i have installed the new ssd disk?

    Yep. Just save the config, install a new pfsense distribution and import the settings.



  • I also use a 64GB SSD, but I think wear levelling can handle its self.

    I use the capacity for squid cache.  About half the drive.
    Without adding ram I shouldn't use the whole drive.
