Travelstar
Travelstar is a brand of 2.5-inch hard disk drives (HDD) currently manufactured by Western Digital. The brand was originally introduced by IBM in 1994 with the announcement of the Travelstar LP, a 2.5-inch 300MB 12.5 mm high HDD.[1] IBM began shipping 2.5-inch HDDs in 1990 without this branding.[2]
The brand was adopted and renamed to "HGST Travelstar" by HGST after it acquired IBM's HDD business in 2003 and continued for a while after HGST was acquired by Western Digital but the HGST prefix is now defunct.
These drives are typically used with laptop computers and small form factor desktop computers. Models are manufactured with capacities ranging from 250 GB to 1 TB, with rotational speeds of 5400 RPM or 7200 RPM and in 7mm or 9.5mm z-heights. All Travelstar drives currently use the SATA interface.
Older models were offered with the PATA interface and some in a 1.8" form factor; such models are no longer manufactured.
