I've been watching the market regarding the new 10X and 31X product sets, but even a month after their release there seems to be little available in terms of third part reviews and/or published perfor...
As noted, the maturity of BTRFS may still represent instability of development, rather than production and maintenance of a deployed product.
ReadyNAS owners use the NAS device to store critical data - the device must reliably protect data. It's the reason for the device.
Achieving maturity and stability is usually challenging for new product deployment. Some claim BTRFS was effectively stable in 2011, yet stability is not supported by evidence now in 2013. The question is: Does "btrfs code that is used in Oracle's Unbreakable Enterprise Kernel" provide sufficient stability for deployment in critical data systems? The benefit of corporate funding could be focused and disciplined verification and validation that could produce great stable code within a reasonable period. Will it be the same in 2014, or 2015? Subjecting users to become unwilling testers ("verification by use") is never a good idea.
From http://www.funtoo.org/wiki/BTRFS_Fun (April 2013):
BTRFS is still experimental even with latest Linux kernels (3.4-rc at date of writing) so be prepared to lose some data sooner or later or hit a severe issue/regressions/"itchy" bugs. Subliminal message: Do not put critical data on BTRFS partitions.
From https://btrfs.wiki.kernel.org/index.php/Main_Page (May 2013):
Btrfs is under heavy development, but every effort is being made to keep the filesystem stable and fast. Because of the speed of development, you should run the latest kernel you can

While the ReadyNAS does run customised Debian Wheezy/Sid, it is making use of Oracle's open source btrfs code that is used in Oracle's Unbreakable Enterprise Kernel. This is a production ready implementation of BTRFS. While BTRFS is still very much a filesystem that is maturing, it does have its advantages over older filesystems such as EXT4.
