Hitachi 7K250 HDD

Hitachi 7K250 HDD boasts as sophisticated marking as IBM drives, for instance. Just look at that: HDS722525VLAT80.

You should read this according to the following rules:

H =Hitachi
D =Deskstar
S =Standard (vs A for Auto for example)
72 =7200 rpm
25 =full capacity =250GB
25 =model capacity =250GB
V =generation code
L =low profile (1-inch form factor)
AT =ATA (or SA =SATA)
8 =8 MB buffer (or 2 =2 MB)
0 =Reserved

But nevertheless, it still looks very familiar:

Maxtor MaxLine Plus II (7Y250M0 and 7Y250P0) HDDs

Maxtor MaxLine Plus II (7Y250M0)

Maxtor MaxLine Plus II (7Y250P0)

The interface of the two Maxtor drives is marked with the last but one letter of the model name. This way 7Y250P0 supports ATA/133 interface and 7Y250M0 supports SerialATA interface.
