As far as I understand it, if you're not making modifications then ext3
is approximately the same as ext2 (and, from memory, read performance is
the same). However, I don't believe there's much of an overhead in 3
over 2 (again, from memory), so I personally would just plump for 3.
You're maybe going to be changing stuff on it occasionally, so it'll be
helpful for those times.

I've never used NTFS in anger on Linux, other than to occasionally do a
bit of diagnosis, so I can't really comment on its current performance
I'm afraid. It's a fact, though, that there will be enormously more
people using ext2/3 on Linux than NTFS so if you're after stability that
may be important.

Given that most of that drive is taken up with actual data (as they're
FLACs) I suspect the differences you've seen are in one of two areas:

1. inodes. ext2/3 will allocate a number in proportion to the size of
the drive (an inode roughly equates to a file or directory). If the
drive is storing only huge files then you'll not be going anywhere near
the default number that will be allocated. If you care, you could tune
this down when creating the filesystem.
2. the 'root reservation'. There's normally 5 or 10% (I forget which) of
a filesystem reserved for root (the logic being that some space should
be available to allow administration in the case of the disk being
filled as things tend to break when disks really do run out of space).
On a very large drive that may equate to a lot of space which you may
think is lost. You can reduce this reserved space at any time with
'tune2fs'.

I don't think there's anything 'wrong' with ext2 - in fact it was the
only option for a long time and it's worked very well for a very large
number of people. Most people just go for ext3 these days (it's the
default on all the distributions I've come across), but it's probably a
personal choice.
