Really depends on what you are scanning.
Scanning P25 control channels is very different from scanning the marine frequencies.
So my answer is fast until we know more about what you want to scan.
I'm certain that if you search for scan rate you will find some examples.
The actual scan rate will vary based on the amount of traffic on the freqs in your list.

...If you set one channel to 45Mhz, the next to 150Mhz, next one to 450MHz and the last to 800MHz, they will scan very slowly in a SDS100/200 scanner. Maybe as slow as 20ch/s. Use channels with frequencies close to each other and it will scan faster than 100ch/s.

Except Ubbe doesn't have one of these scanners and didn't cite a source.So basically the same rule we have always had to use...put the frequencies in numerical order. Interesting.

Yes, but with a much bigger difference in speed than "normal" scanners. It was Upman who mentioned it here on RR that it is more important to sort frequencies with a SDS scanner.So basically the same rule we have always had to use...put the frequencies in numerical order. Interesting.
"Auto" slows down some but not all conventional departments for me. For Phoenix Fire VHF, it slows it to a CRAWL. When using auto on Arizona DPS UHF frequencies, there is no impact. Still scratching my head on that one. The only difference I can think of is that the VHF stuff has DCS's and CTCSS, while the UHF stuff is all CTCSS. I am suspecting that "auto" and DCS don't get along well, but I have not tested to verify yet.Using the '"auto" filter setting with conventional frequencies slows the scan rate down for sure. I think I'm going to change the way I set up my Favorites lists - put all the channels that need 'Invert' in one department, maybe sort that by frequency, then have another department with 'Normal' filter applied, etc, etc.
