I have, and I can comfirm that this really works, you can use the ext4 driver to mount ext3 as well, just to benefit from the improved code, and you can always revert back to plain ext3 when doing this. You can also use the new ext4 features, but then you will not be able to mount it as ext3 again, only ext4. > > > Most important thing for me is speed and security, and, of course, lifetime > > of > > the ssd is also important.

Should you choose to convert to ext4, there are plenty how-to's on the internet such as this one: https://ext4.wiki.kernel.org/index.php/Ext4_Howto#Converting_an_ext3_filesystem_to_ext4 Kind regards, Steven
