Each block on a SSD has a finite number of writes. This is mitigated on modern drives by "spreading" the writes around as you use the drive.

I'm wondering if you partition a SSD into several partitions (a Mac using Boot Camp, for example) if this measure is defeated somewhat - can the writes be spread across the entire drive? Or are they contained strictly within the partition boundaries? Any SSD controller engineers here :)?
