Hitachi Deskstar 7K4000 4TB review
4TB sata hard disk
Hitachi's storage division has been bought by Western Digital, but currently still exists independently. That's good news, as the Hitachi Deskstar 7K4000 4TB hard disk is the best high-capacity hard disk.
It's worth noting that, if you install it in a PC, Windows will split it into two NTFS partitions of 2048GB and 1678GB. If you're running another OS, such as Linux, or install the disk in a NAS, alternative file systems should be able to handle the entire disk.
The SATA3 disk is certainly fast, with a write speed of 151MB/s and a read speed of 160.4MB/s in our large file transfer tests, producing an average speed of 154.8MB/s. Its performance when it came to writing small files was less impressive, at just 32.4MB/s but its small file read speed is a blistering 71.7MB/s, producing an average of 52MB/s.
Although the Deskstar 7K4000 4TB excelled in our large file transfer tests, proving to be one of the fastest HDDs we've ever seen, its handling of small files was a little inconsistent. However, at just 4p per gigabyte, there's no denying that this hard disk is excellent value. Considering you get a five year warranty included, the Hitachi Deskstar 7K4000 4TB wins a Best Buy award.
