WD acquired storage firm HGST a few years ago and although both companies are kept separate, there's a deliberate strategy to prevent products from both companies from overlapping. So WD ends up selling mostly storage solutions for the consumer, OEM and SMB markets, with HGST focusing on the B2B and enterprise side.Amongst all this is an oddity ? the Touro range which comprises of desktop and mobile external hard disk drives, which is technically an HGST brand but is seen as a separate entity entirely. One of its products stands out from the market, the Touro S (otherwise known as the HTOSEA10001BHB), a 1TB 2.5-inch external hard disk drive that has a 7200RPM spinning speed.

Almost all other 2.5-inch hard disk drives run at a comparatively mundane 5400RPM, so in theory, the Touro S should be up to 33% faster than the competition, although there are other factors influencing speed like the number of platters. HGST is more conservative when it comes to detailing the enhanced performance here, quoting only a 23% boost.
