One of the reasons that some folk partition hard drives is that certain parts of the hard drive are supposed to be faster than others. Considering that HDDs are a serial access medium, partitioning, in addition to creating logical partitions, also map to a particular physical set of clusters/blocks on the hard drives
Now, with SSDs, its a whole different ballgame - wear leveling would rely on data being writable anywhere on disk, and with serial access, fragmentation has less of an effect
So.. do partitions on SSDs correlate to physical sectors on a disk like HDDs, or is it abstracted away at a higher level?
