Hitachi Deskstar 7k3000 3TB


This mammoth 3TB disk was unrivalled in our performance tests. It scored above average across the board and was the fastest at reading and writing small files, while performing superbly with large files, too. It also took just 31.6 seconds to load the Crysis game level – again, the fastest on test.

The disk’s performance is helped by its top spin speed of 7,200rpm and SATA3 interface. This means that, in theory, it can transfer data to and from a computer at 600MB/s – twice as fast as SATA2’s 300MB/s. However, SATA3 has only become standard on computers with Intel processors this year, so check whether your computer’s motherboard is SATA3 compatible. Even if it isn’t, the backward compatibility of the Hitachi Deskstar means you can use it on your current PC and it will still serve as an upgrade on your next computer.

The downside to all the 3TB disks we tested is that they can’t be used to replace the main disk in most PCs. Computers fitted with standard BIOS (Basic Input/Output System, which controls the various components on a PC) can only boot from disks of 2.2TB or less. The exception is if you have a 64-bit PC with a motherboard that supports EFI (Extensible Firmware Interface), but these have only recently started appearing on PCs so you’ll need to check your machine’s specificiations. 

Even if your motherboard isn’t equipped with SAT3 or EFI, the Hitachi Deskstar still makes a terrific secondary, non-booting disk on a PC running Windows 7 or Vista (it won’t run on XP). You can store masses of video, music and pictures without having to worry about managing space, and there’s plenty of room for resource-hogging programs that don’t need to be on the boot disk.


This disk was the fastest we tested and produced excellent results across the board. It also comes at a great price – by far the cheapest of the 3TB models, with a price that works out at just 4p per GB. The 3TB capacity should keep most people in free space for years to come. The drawbacks are that it won’t work on Windows XP computers, and even on later versions of Windows it can only be used as a secondary disk, unless you have a compatible EFI motherboard.
