Yes I am aware that it's experimental but the fact I plan to keep everything on an external 3TB HD because of this renders it "use it at your own risk"
Now I did plan to use arch but for some reason it just doubled my first HDDs space not utilizing all the disk space I have which is about 1.2TB.
I know I can't use raid because of the fact they're 2 separate disk sizes, one is a SSD at 120GB, another is at 1TB so obviously raid is out of the question. so what do you guys suggest I do? should I just make the 2 disks seperately and then just use btrfs's add device option?
Now I have used btrfs recently but that was with ubuntu and I think the kernel was 3.5 something so it wasn't the latest 3.6.2 and obviously btrfs will be better in 3.7.0 RC1.
I'm only considering BTRFS because the performance gains instead of using a traditional LVM and EXT4 as it really does slow down boot time but I can't say it doesn't perform well once booted in but btrfs is obviously faster at booting.
So what do guys think I should do? Use btrfs and make a snapshot everyday or for now just use lVM and ext4 and migrate in 6 months?
Hi, mixing a SSD and a 1TB old HDD is not a good thing.
You could use your SSD with the BTRFS trim option and use your 1TB as your /home or even to backup your stuff.
For the rest, do some backup and BTRFS is good enough right now.
My 1TB HDD is not old, it's brand new. 10,000RPM. Not as fast as a SSD but speed/price ratio makes up for that. I'm not going to blow 1K on a 1TB SSD as it's not financially well it is but not going to.
for some reason I can't install with the UUID that btrfs filesystem show gives me.
I guess with btrfs I don't think it should matter as both sda4 and sdb1 have the same uuid or would if I used btrfs device add /dev/sdb1 / "considering / is /mnt/funtoo"
Most of my apps require wine, and photoshop cs6 ran perfect in ubuntu just hope the install process is the same.. as I require photoshop for work but despize windows with a pasion.. it's so buggy but so mainstream people just don't care. If it's a PC it's Windows to them.
Funny though that I prefer Office to libreoffice but I require exchange and linux has no "perfect" exchange alternitive and I find evolution to be desired with exchange it's not ready nor will it ever be.
Other than Photoshop, Office, and some other software (unity as unity 4 is not available yet) I do use open software but doesn't mean I believe richard stallman's sayings as a bible (some people do) Gimp will never replace Photoshop hell not evel coral painter, Linux multimedia studio(whatever it's called) is close to replacing fruity loops but doesn't or will never replace the high end audio tools/software from osx and windows.
woops, went on a rant there.

I don't think you'll get any performance gain with btrfs. They still have a lot of optimizing to do.. Is LVM really that slow?
You will have a gain for sure, since BTRFS can handle the SSD properly.
You can add the SSD and discard options to your /etc/fstab.
BTRFS is still *slow* and especially painful when doing "heavy" I/O on green drives.... Will give ZFS on Linux a try when I will have some free time, it has been updated recently.
The default mount option for btrfs is not good for performance. But you can put customized mount option to tune for performance, e.g compress=lzo give some boost.
I am using only btrfs as the filesystem for daily usage, 2 partition mount in btrfs raid 0 mode which I store kernel sources git tree in. This system works just fine.
Below is the mount option I used.
/dev/sda3 on /home type btrfs (rw,noatime,device=/dev/sda3,device=/dev/sdb1,compress=lzo,space_cache,inode_cache,autodefrag)
