For the first time I will be using a 1-2 Terrabyte hard drive on any SL release, in particular,  on  an older SL5.0 (boron) OS.   

There's plenty on the web about pros and cons for larger file systems (resier, xfs, ext3, ext4, ...).   I've usually stayed with ext3 (200-500 Gb HD that are NFS mounted to linux or windows using MS windows for unix).  So, vanilla; not too splashy a set up.  No clusters.  I've not used LVM. 

I think my question is which of these choices is as well developed, mature, and easy to use as ext3 for the SL5.0 boron version of SL?   I'm most familiar with ext3 and do these stray IT tasks as needed, so I've not kept up on the latest and greatest.

Thanks for any comments,
Bill Lutter
