Not only that, but it comes with layout lines already on it! But some folks do not always line them up!:D

It is roofing plywood, the lines are used to align the shingles. It is very, very cheap ($6 or less for a 4x8x1/2" sheet). One side is very smooth and the other has a waffle texture like the the back of pegboard. The stuff works very easily with a good carbide blade. I made 5 display pedestals out of one sheet, and when primed and painted they work great. The only issues are the edges are a little fragile and the stuff stinks until primed.

And what happens when it gets wet?:(

The same thing as any wood product. It soaks up water and starts to come apart.

Methinks much faster than a board or plywood. Personally I prefer board sheeting(shiplap), but then my domicile is over a half century from being a tree in the forest.

The newer OSB stuff is better than the stuff from the 1980's. I have some that has been on the south wall of an old barn in full weather unpainted. It has been weathering there for maybe 6 years now and is still solid.
Some I used on an old shed in the 1980's looked like a woolly mammoth in about a year.
I use a lot of it in horse stalls because if they kick through it they may get a few scratches but it breaks with a shaggy edge instead of with long sharp splinters.
Virtually nothing is "bad"... Some stuff is just considered bad if it is used in the wrong application.

I assume that wall is vertical(drains quickly!!!).

Yes OSB is much gooder than 'particle board'.
