the bulk mirka's i have are great.
Mostly i find it depends on what you're sanding. Raw wood like oak, cherry, maple, black
walnut allows the discs to last a long time. Heavy resin woods like pine, gum up quickly
as do finished surfaces.

Yea, Hooking up the sander to a shop vac seems to help too.
Sands better, disks last longer...............

The proper use of planes and scrapers extend the life of sanding discs
immensely.

No. I have the Porter-Cable 333 and use Norton hook and
loop disks (buy them by the "contractor pack" of 25 at Home
Depot) and they haven't made me think they "wear out very
quickly." My experience is mostly with white oak and, no
matter the grit, I fill the collector (get lots of dust) and never
give "changing the disk" a thought.

well, if a disk lasted for 20 solid minutes at full speed (the only
speed I use, since I didn't get a VS PC sander) I'd consider that
normal. I buy 25 packs of ROS papers and replace worn pads often. I
don't even think about it, as the cost isn't that high... Now if I was
buying those little packages, I might get my shorts in a bunch if every
couple of minutes I burned through a bucks worth of paper...I'm just as
likely to tear a pad as wear it out, anyway, on some projects.

The disc cost you 50 cents at the most, if bought in bulk. 20 sf of
sanding is petty good -- 2.5c a sf. Sandpaper is considered
an item you have to replace often --

Let's say a 100 grit disk at full speed on yellow pine will last about
10 minutes before it begins to take off so little material it's hardly
worth continuing. Of course it doesn't quit suddenly and I've never
tried to time it, so maybe that could be 5--20 minutes.
Maybe that's about 15-20 sq-ft of Baltic plywood.
All those are wild guesses.

Yes. The experience changed with I changed to professional
quality disks. I'm using Klingspore and find they last about a dozen
times longer. Check the archives and you'll probable find other
brands recommended.
Good luck,
Peter

I have also had good results with the Klingspore disks and you can get some
good deals in their "bargain boxes" in bulk quantities. I was using the PC
brand but they seem to be really low quality.

I think you're on to something. I had a board of rough cut 5/4 cherry that
I needed to take down to 3/4". Took me a whole box of sanding disks to get
it there.

Someone published a study a few years ago comparing sandpaper costs to
labor costs. I just looked and cannot find the study but maybe someone else
has it.
The study had a chart that showed how often you should change the
sandpaper based on the cost of sandpaper and the cost of labor. If you were
paying $10 per hour for labor and X for sandpaper, you should change the
paper every Y minutes.
The amazing part was that the study recopmmended changing the paper every
three to five minutes for most reasonable combinations of paper and labor
costs. The sanding efficiency of the paper dropped off quite quickly so it
made exonmical sense to change the paper early and often.
I hope that some can find the original study. It might have been done by
Klingspor.
