How Hard Disk Works

Your hard drive has a number of magnetized platters. The spindle spins the platters at a very fast speed while a read/write head scans over them both looking for reading and writing information. The effectiveness of your hard drive depends on how much of its capacity remains unused, fragmentation and its data transfer rate, which in turn is dependent on its connection type and the drive’s spin rate. In buying a hard drive, you may want to compare the prices of say a 160GB drive against two 80 GB drives. The thing with 2 hard drives is that, If one drive fails all is not lost. Although today’s hard disks are durable pieces of hardware, so long as you do not abuse them, it can provide you a long time of hassle free data storage.
