Where is the data coming from? During the testing I did on LTO vs. SDLT I observed similar behavior. I concluded that the RAID5 set containing my disk storage pools was the bottleneck.

Normally you would assume a max. throughput of 8 * 15 MB/s = 120 MB/s when making a backup. Anyone for comments and/or solutions?
