"Nearline" 3.5" WD drives (RE, Black, etc), and models used in some of the firm's 3.5" HDD-based externals, are listed on a separate page.Ģ0GB/platter Section (all drives under here use platters that can hold 20GB of data apiece.) Models that are essentially relabeled Hitachi/HGST designs are marked accordingly. All of these + models of the old Protégé entry-level line are covered on this page. Eventually, using these lines as a base, WD released several families intended for TV DVRs and 24/7 surveillance: the Purples, AVs (later with the non-publicized "Connected Home" mark), and (long-discontinued) Performers. The Caviar (later rebranded as Blue) line are WD's mainstream bread-and-butter product, standardized to 7200RPM by ~2003, while the Caviar GP (later rebranded as Green, before being merged with Blue) introduced in 2007 offered much higher capacities at the cost of decreased RPM. Miscellaneous details of possible interest are mentioned at my discretion. 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. It works very simply: a (3/6) ratio indicates three disks and six read/write heads. A platter-head ratio is shown next to the total capacity tag in brackets.
The total capacity of each individual model is shown beside each model number. Only the manufacturer knows the exact capacity per platter. All capacity values are rounded: "40GB" and "1.33TB" may actually be 42,646.25MB and 1333.5666GB. Models are sorted into sections by platter density.Īll displayed data capacities follow the storage industry's standardized "1 megabyte = 1,000,000 bytes" rule.
Here are all of the models currently in the database for this manufacturer and drive width.
