If reiserfs is dead ended.. then the choice is simple.. but mind if i ask.. with that much space what kinda raid system are you using 5,10 ?? will the filesystem hold a lot of big files or are they mostly small files (under a meg).. If you wanting the best disk performance.. look at putting your journal file a different disk(s).. while your writing data to the your T the system will not have to stop that write process and write its journal.. Also look at changing with your I/O shecdular. But before doing that. Look on the web for benchmarks that match your current setup, since it takes a lot of time to complie the data.. no need to remake the wheel with this testing.. Sorry to be long winded.. but love to tweak systems..!!! I got most of my info from the IBM press Linux server performance book..
