Re: Best File System for partitions over 600GB

Hi Roberto.


I see. I was asking since I have a whole drive full of videos and such which are
usually between 100MB and 300MB per file. So I guess XFS would not really be the
best choice for them. I got ext3 everywhere at the moment and wondered if I
could get a bit more performance by using another filesystem. And since I only
used ext3 up until now, I don???t really know which other filesystem to trust.

I would certainly trust XFS. Of course, if you don't have your machine
on an UPS, it can cause problems on a crash or power outage. How are
your video files being used? Played locally? Streamed to one or two
devices? Streamed to hundreds of devices?

Unless you are streaming to many devices, it is likely that you are not
yet hitting a bottleneck. As they say, "if it ain't broke." That said,
do you notice a particular performance problem?

XFS supports files up to a size of 8
exabytes and filesystems also of size 8 exabytes. I am not sure of the
limitations on JFS.

OK, that seems only important for enterprise levels. I don???t think that I will
reach these sizes at the moment.

I read on Slashdot a while back that Seagate announced 37.5 TB drives
will be available in a few years. Petabyte-sized home RAIDs won't be
far off :-)
