Here are all of the models currently in the database for this manufacturer and drive width. Models are sorted into sections by platter density.
Some tips:
All displayed data capacities follow the storage industry's standardized "1 megabyte = 1,000,000 bytes" rule.
All capacity values are rounded: "40GB" and "1.33TB" may actually be 42,646.25[...]MB and 1333.5666[...]GB. Only the manufacturer knows the exact capacity per platter.
The total capacity of each individual model is shown beside each model number.
A platter-head ratio is shown next to the total capacity tag in brackets. It works very simply: a (3/6) ratio indicates three disks and six read/write heads. Models that "waste" a substantial amount of their actual total capacity in order to fit into certain capacity brackets (such as a 320GB unit based on one 500GB platter and two heads) are marked accordingly as [short-stroked].
Miscellaneous details of possible interest are mentioned at my discretion.
Assume that all models are 9.5mm-thick except when tagged otherwise.
This section includes models containing "IBM DNA", produced before and after the 2003 Hitachi buyout of IBM Storage. Models produced following the 2012 Western Digital buyout of Hitachi GST are also included, including those that are visibly WD designs but carry traditional HGST branding. For Hitachi in-house-designed 2.5" models ("DK" prefix), 1.8" models, and earlier Endurastars, check the other section.
Models with "HTE" prefix are "Enhanced Availability" models, meant "for applications needing around-the-clock access in lower-transaction environments". This is related to what the "(E)" given in the family name of some subsections on this page is; for example, the EA models of the 5K100 lineup are, as decreed by Hitachi, actually part of an E5K100 lineup. It follows that the "(E)5K100" subsection includes both lineups, for brevity.
