Hard disk drives

IBM sold its HDD manufacturing to Hitachi, who continued to use the Travelstar name for notebook 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 single 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.
