I have just started my first conversion on a 16 core, 192GB server with SSD database/activelog and 36 nearline drives. It seems to be going along at speeds of about 1-1.5TB/hour. That is 1-1.5TB/hour of managed data. Very heavy on the source disks, pretty easy on the target disks (same storage subsystem). Just a reference for you guy's performance wise.
