I have an external USB hard drive (for backups) on our server. I's shared as "T". Other computer backup to \server\T.
I'd like to also refer to that drive locally as \server\T rather than (say D:) because the drive letter changes when I rotate USB drives.
Is there a performance penalty to referring to it by it's UNC name? (I.e., as if Windows XP were actually going out on the network to get to the drive.)
