I think that't my favorite part about these new high density drives. Don't get me wrong, a TB (or more!) in a single 3.5" drive is an amazing thing, but even moreso is the ability to have a higher transfer rate. What works out even better is the fact that unlike most other filesystems, I think ZFS can really take advantage of that. I was doing so heavy read/write activity on my colo-ed box, and it's neat to watch 'zpool iostat' since it was reading at a constant rate but the write would wait for the txg and so there would be no write activity and then full blast for a second. That's just a perfect combination of technologies. Now to get that box upgraded to snv90 or better. ;) -brian -- "Coding in C is like sending a 3 year old to do groceries.
