If you thought that hard disks are going to die soon and they are going to be replaced by SSDs – then you are quite right. Why would people go for traditional hard disks when there are these cool SSD lurking around? The only problem with SSDs is that they are not quite popular in the market due to their high price. Even the 64 GB ones are priced at a really high rate. Price will come down but we don’t know why. What we do know is that when they get affordable – these SSDs will quickly kill the hard disk because of their superiority. The SSDs are very small and the power consumption is really less because they don’t have any moving parts. Also, SSDs don’t make much noise while they are in action. Hard disks, on the other hand, start with the irritating whinning noise (remember the noise that you hear when you press the power button?). Higher end cabinets take care of these hard disk noises by giving those rubber screws which absorb all the sound but they come at a price.
However, the high price of the SSDs are making sure that the hard disks don’t die anytime soon and companies like Toshiba are taking full advantage of that. The manufacturer recently announced a new hard disk which has a storage capacity of 2.5 TB per square inch. This is certainly a lot; it is in fact of five times more than what other companies are offering right now. It is achieved by putting lithographed magnetic material islands on the individual bits. Because of this, the charge of individual bits are protected and it also lets the sectors to be much smaller. There is still work to be done here, Toshiba says these hard disks won’t come in the market before 2013.
