Hard disk capacities are developing at an ever-growing rate and the price each GB has gone down to the point where can acquire you Two TB of memory space, that is a mere 5 cents a gigabyte. This equates to the thousands of dollars you would have to expenditure on a hard disk 20 years before. The reason prices have gone down is that the density for every platter on the hard drive has raised while the size of the drive has remained the similar. Another elements is the advent of Solid State Drives for the mainstream user.


Western Digital has been creating hard disk drives for a long time being one of the former client hard disk producers and was one of the fist drive producers to hit 1TB for client hard disks and 2TB of storage space. Now they are establishing the first 3TB Hard Disk drives and to hit the market the Western Digital Caviar Green Three TB drive.

The Western Digital Three TB hard disk drive is a member of the 5th era of Caviar Green product line. This drive has a capacity of 3000GB or 3 Terabytes which is fairly amazing. The drive has 4 platters each of which contains 750GB of information storage capacity. The drive has a 64MB cache and is on the SATA 2 interface. As is common with SATA drives, Native Command Queuing is supported.


One issue that producers have with the raising HDD space is that CPU boards are utilizing Master Boot Records and the system BIOS. Hard Disk Drives generally have a 512 byte part size which if you function out the math gives a maximum size of 2.19TB or 2 to the 32nd power of memory space. This is a difficult limit and is same to what occurs when you test to adjust Four GB of memory into a system functioning 32-bit Windows.


One way to separate the 2.19TB barrier is to utilize a bigger part size and maintain the number of addressable blocks the similar. Utilizing a sector size of 4096 bytes would answer to have up to 17.59TB of addressable space, which is 2 to the 32nd power times 4096.
