Yes, they are pretty fast. Our SDLT are getting up to 30 MB/sec, or 1.75GB a minute = 100GB an hour. This is for the local SAN attached Unix servers. The other systems we backup over the LAN have gotten up to 20MB/sec, if they are running GigEthernet. I've noticed quite a speed variance between server backups that is attributed to the CPU/system speed of the server that's being backed up.
