I have a new Hitachi 2TB HDD and I'm going to put it in an eSATA
external enclosure for music and movie storage. I read some where
that a journaled drive can be slower than one that's just Mac OS
extended. I ask because my son has two of these large drives and his
boot time can be really long and we were told it's because the
journaled drives are a drag on the system.
Is there any support for this or is it picking pepper fro fly s..t?
Journaling is THE main reason why our HFS+ volumes don't end up being
corrupted often. It costs maybe -maybe- 0.05% of your i/o bandwidth
to maintain that log.
During mount operation, because of that journal, the file system can
be verified MUCH faster than normal. And certain repairs can be done
on the fly using the journal entries.
If your son is having difficulties at boot time, then you should
check his system log to figure out what's wrong.
