How to read the HDD model number
Example:
HDS722516VLAT20 = 160GB / 2MB
H = Hitachi
D = Deskstar
S = Standard (vs A for Auto for example)
72 = 7200 rpm
25 = full capacity = 250GB
16 = model capacity = 160GB
V = generation code
L = 1-inch form factor
AT = ATA (or SA = SATA)
2 = 2 MB buffer (or 8 = 8 MB)
0 = Reserved
