Thus spake Caffeinate The World ("CTW> ") sometime Yesterday...

Hiya, Caf!

CTW> 80 Gig SATA Seagate ST380013AS 8MB cache $137.00
                         ^^^^^^^^^^
ST: "Seagate Technology"-''||||||||
 3: Form Factor Designator-'|||||||
80013: Capacity (MB, raw)---'''''||
 A: ATA -------------------------'|
 S: ? ----------------------------'

[I'm not sure what the 'S' is for; being an 80G drive I'm sure it's
 probably at least Ultra/100, as the "ST320420A" I have will handle
 Ultra/66.]

In short, the "13" suffix is part of the capacity and has nothing to
do with the cache size or any other attribute.  Maybe the 'S' at the
end indicates that there's a cache somewhere.
