Care to elaborate? I'd be interested to hear why.

Do bear in mind that this is a community of volunteers. Not getting an immediate reply does not mean that you are being ignored, it is just that we sometimes have other things to attend to first.
And as suggested by onebuck, it would be in your best interest to open a topic of your own - preferably one with a title that clearly states the nature of your problem.

I also use ext3. Checked for alternatives. All of them had downsides for me, and offered no real benefit.

Ext4 is now stable and kicking. Check this if you want to know how to convert.

http://kernelnewbies.org/Ext4

XFS is ok, that is, as long as you can guarantee a stable power supply. So, unless you have a good UPS with some hours of autonomy at least, I wouldn't use it for anything important. The kind of "big files" that are really big for XFS are in the range of hundreds of GBs or terabytes. A video is not "big" for XFS really. Ext3 can handle these files just as well. However, ext4 should handle files of any size (well, of any imaginable size for nowadays standard).

I wonder whether that is still valid as the Linux version has nobarrier disabled by default. It is precisely that nobarrier option that can make XFS unreliable in case of power loss as it caches a lot more aggresively in order to maximize performance (I have seen speed increases of 10MB/s and more, from nearly 70 to about 80 ).
Its real downside has tended to be file deletion but by this can be solved by increasing the size and the number of log buffers.

Admittedly I am no expert in XFS, I just talk from my experience. With factory settings XFS has given me more than one headache. The worst thing about it is that it's fsck tool is (or used to be) an empty wrapper that reports nothing. That means that all the problems remained hidden until I decided (for no particular reason) to check manually one day from a livecd.

Guess what, surprise.

I haven't put much effort into "fixing" it. I have no real reason really. Ext3 performs ok and is safe. No fs is perfect of course. If such a thing existed there wouldn't be discussions all over the net about the topic
