IBM Travelstar harddisk drives are rebranded Hitachi Travelstar drives.
IBM/Hitachi harddisk naming scheme
Hitachi harddisk names (on modern drives) are a set of letters and numbers that in fact tell a lot about the specifications of the drive. The designation follows the pattern:
| H | T | S | 72 | 60 | 60 | M | 9 | AT | 00 |
| H | [t] | [?] | [rr] | [??] | [ss] | [?] | [h] | [ii] | [??] |
- the H is for Hitachi
- [t] is a signle letter designating the drive type, like
- T = Travelstar
- D = Deskstar
- E = Endurastar
- following is a mystical single letter.
- [rr] is the first two digits of speed in RPM, i.e. 54 for 5400 RPM.
- next two are strange, they match the marketing/branding name for the drives, like 7K60 would be HTS7260... . So they might just separate drive generations or something like that. But they also match the size of the biggest available drive in that series.
- [ss] is two digits giving the size in GB. 100gig drives have a 10 here.
- following is a letter that is probably placed as a riddle for anyone who wants to interpret the naming scheme.
- [h] is the drives height in full millimeters, first digit, i.e. 9 for 9.5mm .
- [ii] is a two digit code for the drives interface, like this:
- AT = IDE/ATA
- SA = IDE/SATA
- CE = IDE/ZIF
- CF = Compact Flash
- L3 = SCSI/Ultra320
- LF = FC-AL
- two numerical digits are following, might be some kind of revision, might be something else.
