It doesn't, really. The OS will happily deference the symlinks you
create as needed.
Also, the health of the harddrive(s) which will most likely be SATA
Decent-quality disk drives shouldn't have any problems operating
under continuous load, but some low-end "desktop" drives aren't rated
for continuous operation. You should probably look into setting up a
RAID-1, -10, or -5 configuration.
It is my understanding that symlinks only affects the file
allocation table, and not the physical data blocks? This would mean
that the impact isn't so terrible, as the changes will be contained
to a relatively small part of the beginning of the disk, correct?
No, that is not correct.
The FFS doesn't have a single "file allocation table", it has inodes
scattered throughout the various cylinder groups, which span the
entire disk surface. Inodes contain some metadata which corresponds
to portions of the MS-DOS FAT, and some systems implement small
symlinks (aka "fast symlinks") within the inode entry, but longer
symlinks are stored in the data blocks in a fashion similar to
keeping text data in a normal file.
