Western Digital launched the industry's first 2 TB hard disk
drive back in January of 2009, the 2 TB WD Caviar Green. This was
followed up by the Hitachi 7K2000 in August 2009 - the first 2 TB hard
disk drive with a spindle speed of 7,200 RPM. Unfortunately, there has
been no further progress since then.
It was not for a lack of trying though. Every hard disk drive
manufacturer in the world has to deal with the problem of the 2.1 TB
capacity limit, which was brought about by the LBA addressing limit in
32-bit operating systems. This problem can be solved by switching to
48-bits Long LBA, but this will only work with newer 64-bit operating
systems. There was also the issue of updating the GUID Partition Table
(GPT) to support Master Boot Record partitions that are larger than
2.1 TB. The good news is that they are close to a solution!
