Hitachi GST, which was acquired by Western Digital earlier this year, has announced the availability of an external 4TB hard disk drive which, unlike the Seagate Goflex model unveiled earlier this week, is aimed squarely at professionals.
Launched at the IBC 2011 event in Amsterdam, the G-Drive has four 1TB platters with a 625Gb per square inch density and spinning at 7200rpm.
The drive will be available in October with an eSATA, Firewire 800 and USB 2.0 port but very strangely, no USB 3.0 as it stands; a Thunderbolt based version will also go on sale in Q4 2011 together with pricing details.
At the same time, Hitachi has unveiled a new G-RAID solution which contains two of these 4TB drive in a RAID-0 configuration with a Thunderbolt interface only, making it ideal for Mac enthusiasts (but leaving others on the PC platform in the dark for the foreseeable future).
No details about performance or benchmark figures have been published yet but the G-RAID drive - whose aluminium enclosure acts as a heatsink - is able to handle "multi-stream compressed HD workflows including REDCODE, DVCPro HD, XDCAM HD and ProRes 422" according to Hitachi.
