Setting up Snapraid on persistent USB LinuxMint

First off... Im a linux noob for the most part. Im familiar with linux but by no means a linux power user.

I installed LinuxMint onto the thumb drive with Universal USB Installer and gave it 4gb of persistant storage space. It seems to be significantly slower then if I just create and use a live thumb drive.

Some things dont seem to be working like they would with a normal live usb drive as Ive messed around a bit with them. Updates for instance error out asking me to do something with apt-cdrom command. A normal live cd works perfectly fine with updates.

Also, when I edit fstab in the persistent usb drive it does not save and update. It reverts back after I restart the computer.

If I want to run my OS for Snapraid from a USB drive what do you recommend I do and start with? Any tutorials you guys can point me to?
 
Also, would the method that I chose to create a persistent live CD reduce wear on the thumb drive? If not, I would ideally like something that does.
 
You probably want to do a full install, not a persistent live install. A persistent live install is well-suited for running on many different computers and saving your documents and such, but it is slower than a full-install, and does not allow you to modify all the system settings. A full-install is better if you will just be running on one specific computer.

With a full install, you would obviously NOT want to create a swap partition nor would you want a swap file on your flash drive (make sure swap is off and that your computer has enough RAM). You would probably want to mount with the noatime option, and once everything is working you might consider having logs written to tmpfs, which is RAM based and would not be persistent with reboots (which is why you might not want to do it until everything is working).

You could also consider F2FS for your root partition. I think you would probably still need a small ext4 boot partition, since I don't think grub or syslinux can boot from F2FS (although that may have changed recently).

I'm not aware of any distro that is completely optimized for a full-install to a USB flash drive. That does not mean it does not exist -- I've never really looked into it since I would just use a USB or SATA or mSATA SSD myself. The closest thing I know of is Puppy linux, which I believe does have some optimizations that reduce writes.

All that being said... it might make more sense for me to grab a small hard drive. I can probably get a 160gb locally for $10-15.

I think I saw your username on a Linux forum I found in a Google search talking about Snspraid...
