How to Read the Deskstar Model Number
Example:
HDS725050KLA360 = 500GB/16MB
H= Hitachi D = Deskstar
S = Standard (vs T for
72 = 7200 RPM
50 = full capacity = 500GB
50 = model capacity = 500GB (unless 1 in last position) K = generation code
L = height
A3= SATA 3.0Gb/s
6 = 16MB buffer
0 = 500GB model (1=400GB mode
