Western Digital has upped the capacity of its Passport external hard disk drive to 120GB. The drives are based on WD's own Scorpio line of 2.5in notebook-oriented HDDs, and since they too were recently upgraded to 120GB, it's no surprise that the Passport series now offers that capacity in addition to the 40, 60, 80 and 100GB versions already shipping.

The drives are bus-powered and require a free USB 2.0 port. Inside the 14.4 x 8.9 x 2.1cm shell - which WD describes as "a textured, non-slip rugged protective case" - the Scorpio runs at 5,400rpm and incorporates 2MB of cache. It offers a mean seek time of 12ms.

WD said the drives are shipping now and will set UK buyers back around £159 inc. VAT - US consumers will pay around $200. Completists can purchase a carry-case for an extra £20/$25. ®
