how to select a rootfs for embedded linux based hardisk?

[zhuzhenhua]

dear all
          i want to port the linux to our board based hardisk with
mips arch. i do not find too much file sytem for rootfs on hardisk
besides ext2/ext3.
but it seems ext2/ext3 is not suitable for embedded system.
 does someone have idea or experience with these products?

thanks for any hints.

Best regards

How large is your hard drive exactly and is it a real IDE hard drive
or some kind of flash?  If the disk/flash is very small, ext3 may be a
bad choice since it's a journalling file system which means that a)
it'll take up quite a significant portion of space on a small drive
and b) it'll write to the same sectors all the time, which will kill
the flash in no time.
