Setting up 4 of the LaCie "5big 7.5TB Network" NAS devices.
The plan was to use them to catch data we were pulling off of the Amazon S3 storage cloud via an insane internet connection (25 megabytes/second sustained via http requests to amazon S3).
This is before we realized how badly they perform. We could not write to the CIFS shares over gigabit ethernet at anything higher than 6MB/second.
When your internet connection is faster than your local-LAN storage you know you have a problem.
