Hitachi Travelstar 7k60 Hard Drive
 

I ended up choosing a Hitachi Travelstar 7k60 to replace the 60gig 4200rpm
that came installed in my laptop. The “7” in the beginning of the model name
indicates the spindle rotation speed of 7,200rpm, and the two last digits stand
for the storage capacity of 60GB. The drive uses two platters with the maximum
data density of 30GB and four read/write heads. The buffer size is 8MB, the
average seek time is 10msec, and the latency equals 4.2msec.
