I just checked my system, and it looks like it's set for 512k blocks:

I assume the installer chose the block size, since I basically did a
"next, next, next" installation. Should I have chosen something different?

Ah, ok... I see. My first drive is a Windows drive, the second is Linux:

I wonder why the installer chose a 512k block size on my largest
partition, but 4096 for my swap? I don't recall seeing a block size
option during installation, but I may very well have missed it.
I'll throw it out there again, though: should I have done something
different during installation?
