The scramble for more data storage (with more versatility) is never ending. Just about everything in our lives today are being stored digitally : music, photos, videos, documents, arts & crafts etc. And the market responded with various types of data storage designed to meet everyone’s needs.

The Star (InTech) on 3rd April 2008 reported that Western Digital has recently produced a one terabyte (TB) hard drives. Once considered as the stuff of dreams as it requires a massive budget, now one terabyte drives have come down a lot in price to just US$200 (which boils down to roughly RM660.00 !). Thanks to competition among manufacturers.

Western Digital also claims that its new “green” terabyte hard drive spins at a variable rate of between 5,400 to 7,200 revolutions per minute (RPM). Wow that’s really fast guys ! But let us not forget that a slower spin rate allows the drive to use less electricity and run quieter than the faster drives.

Probably the following equations may help some of us get some idea how large this 1 TB of storage space really is …

8 Bit = 1 Byte
(Note: A byte is a basic storage unit in computer memory. A byte of 8 bits which are grouped together as a unit can provide enough different combinations of 0s and 1s to represent 256 individual characters)

1 Kilobyte (KB or K) = 1000 Bytes (actually 1,024 bytes to be exact)
1 Megabyte (MB) = 1,000 KB = 1,000,000 Bytes (1 million bytes)
1 Gigabyte (GB) = 1,000 MB = 1,000,000,000 Bytes (1 billion bytes)
1 Terabyte (TB) = 1,000 GB = 1,000,000,000,000 Bytes (1 trillion bytes)
Hey Yatie, bila KOMASA nak jual 1 TB nih ? :)
