Yes it is. This is due to the outer area's of the harddrives' platter moving faster under the heads then the inside area.
Harddrives natively fill from the outside first so your first installed stuff , usually the OS, gets installed ther by default.
Placing the most used files there does have in impact on the files speed to load but few apps rely on a single file and typically load many files. This forces the head to change track and introduces delay while the head repositions and while the data rotates around under the head again. This is why HDD's are very good at Sequential reads/writes (allt he data is in a row/line) and why they are so bad at random (The heads have to move)
