brtfs ssd mode texted on phoronix

[Miguel F Mascarenhas Sousa Filipe]

Hi there,

The phoronix guy tested btrfs in Fedora 11 + rawhide in SSD mode and
normal mode in a bunch of tests from the phoronix-test-suite.

http://www.phoronix.com/scan.php?page=article&item=btrfs_ssd_mode&num=1

The drive was a: OCZ Vertex SATA 2.0 SSD
The drive is supposedly not that bad, of course is worse than the
intel X-25 MLC one, but much more consumer level and afordable.

these are mostly sintetic tests but I think are worth the look.

SSD mode had worse results almost consistently.

Kind regards,

Thanks for sending this along.  I just posted to the forum that 2.6.30
should be faster with -o ssd.
