I have a 1TB external seagate hard drive that i use it with my dell inspiron 1525 laptop running UBuntu 9.04. I dont intend to share my hdd with anyone, so my laptop is the only comp i will plug it into. Its on NTFS right now, it auto mounts as soon as i plug it in and i can transfer data without worrying about permissions.
But, ntfs-3g takes up a lot of cpu and resources, particularly for long running data transfers of over 20G. So i want to shift to a native linux file system for my hdd (probably ext4 or ext3 ?).
1) Will there be a significant difference in data transfer rate( <= 26 MBps currently) , cpu usage and system responsiveness with a native file system as opposed to NTFS ?
2) Will auto mounting work or do i have to manually mount it every time.
3) What do i have to do to mask file system permissions or to make sure that the permissions don't get in the way like in NTFS ?
I don't intend to ever use the drive in windows.
