No, wear is not going to be significantly different.
You didn't say whether you are talking about hard disks (where location
makes a difference, but "wear" on the drive motor is insignificant to
the disk's expected lifetime), or flash disks (where people often worry
about "wear", though location is irrelevant and wear is also irrelevant
for most uses of all but the most cheapo disks).
