There are concerns that everyone's currently fast performing LVM file systems will suddenly become doggish once barrier support is included and in some cases it will be true. Using a separate SSD device as a journal can help in some cases.
That's only if you are using ext3/ext4 and data=journal. Are SSDs faster than bbu nvram cards?
