Btrfs VS Ext4

[slaughterer]

Hey all,i am planing to buy a brand new ssd.
I would like to ask which fs is the best in terms of taking advantage of the ssd???For example let's say desenegrading less the disk.
I will probably buy samsung 840 pro series.

I have a 2TB BTRFS filesystem on a pair of WD1002 SATA 3 hdds, where I keep my data.  Having said that, AFAIK BTRFS does not offer any advantage over ext4 when used on a single partition, whether hdd or SSD.

I run my siduction OS on a SSD, ext4, with the journaling slowed down from the default 5 seconds to 120 seconds.  Works great -- very fast.

One possible problem that you could have, depending on your BIOS, is whether that Samsung SSD will be recognized as a bootable device.  If it is not, you'll need a second hdd or SSD for the /boot partition (this happened to me).

Last time i googled benchmarks, ext4 was faster.
I use ext4 on my ssd. If you do not need btrfs features, i'd use ext4

Ok tnx a lot for the answers guys!

More features produce less performance, if you think how it is programed:
case VAR in
featureA)...
featureB)...
...
But new software might have a inovative algorithm which perform better.

In case of btrfs there are much more features, e.g.:
- if you need LVM2: This feature will be better maintained by btrfs in the future.
- if you want snapshots: After the release of Debian, when our main Debian release "unstable" (sid) will unfreeze, this might save your day!

If you think of
- data importance: your /home data has importance. siduction is quickly reinstalled. The rock solid proven filesystem is not needed for /-"root" but for /home.
- performance: the siduction system once started doesn't need to have the performance of your constant work partition /home

both my arguments signal using old and stable ext4 filesystem for /home. Most people argue the other way round, I don't know why ...
