What kind of miles are you getting on casettes?

Why would you think speed is relevant?

Chain - 4000 mi.
Cassette - only if shifting is degraded.
That's just me.

I've gone through at least 5 chains with my cassette and not even a hint of cassette wear, even though I shift while out of the saddle all the time. Each chain lasts a minimum of 1.5k miles, so I would say my cassette has close to 8k miles on it.

As long as you're keeping your chain well maintained and it ain't stretched, the cassette should be fine. That's my understanding anyway.
Get yourself a chain wear indicator tool to check for signs of stretch.

Since I finally started keeping track of mileage on various cassettes, I haven't retired one, so I don't know the longest life to finish, but the one I have been using the longest, an Ultegra 12-27 cassette, has 9,839 miles on it and is still working fine.

I've gotten about 7000 miles in 4 years out of a 9 speed Ultegra chain and cassette.
Obviously, I cleaned the chain regularly and lubed it as well. I used the Finish Line teflon lube and the Park chain cleaner with citrus degreaser.
I recently measured the chain for wear with one of the cheapy Nashbar tools. It did not even show .75 wear. Using a much better Park tool gauge, my mechanic said it was close to time to replace the chain.
I was planning to replace the frame (fit issues) so I decided to just buy a new chain. I upgraded the chain to a 9 spd DA chain and also bought a new DA cassette. While I'm waiting for that to arrive, I'm using the old Ultegra cassette with the brand new chain. There is absolutely no slip from the cassette. I think it still has a lot of use left, so I'm moving it to my trainer wheel.
Based on this experience, I can say that the shifting was starting to degrade as the miles racked up, but this was only noticable when I went to a new drivetrain. I never missed shifts or had any problems with the Ultegra components.
I probably won't be letting it go as long next time, but I guess I could. Obviously, YMMV.

Oh, Lord. I must've gone through thousands of miles on my old cassette before I replaced it. The only reason why I had to was because I lost the wheelset with the original cassette on it

I get about 2k miles on a chain. I find lots of climbing will stretch my chain faster than anything else.
Average about 10k on a cassette. I probably do not need to change the cassette out at this point, but I can't resist buying something for my ride every now and again.

I had over 12,000 miles on an Ultegra chain/cassette before finally changing it about halfway through the season.

Speed won't make a difference. Power output probably will. I got tons of miles out of a cassette when I was 120 lb and didn't need a lot of wattage to get moving.

I seem to remember someone saying here one time that they replace their cassette when they replace their chain. That's anal.

I should have also mentioned that the material the cassette is made of will make the largest impact.

I've heard 2500 miles for cassettes! Craziness. Just liking chaning motor oil every 3,000 miles.
