Why Solid State Drives Are Better Than Hard Disks?

Solid State Drives (SSD) are straight substitutes for the hard disks or standard disk drives on your personal computer. This applies to all computer types including desktops, laptops, notebooks, and netbooks. In addition, many SSD drives can also be connected to any of these computers as an external drive for extra storage using a USB port.

SSD vs HDD

Unfortunately, hard disk drives use a spinning platter, which stores your computer data, and a mechanism to read and write this data as required. This means they have several different mechanical moving parts that mean today’s hard disks can easily be damaged if they suffer a knock when being carried or moved.

The consequences of this can be catastrophic if the computer is powered up and active at this time. Solid-state drives, on the other hand, have no moving parts at all and are therefore much more robust and they will not be susceptible to damage even if they are knocked or even dropped during use!

An SSD drive is built entirely from memory chips and a controller to perform the read/write functions to retrieve and store your computer data.

The capacity of the commercial version of solid-state devices has already reached 512 gigabytes, so they can easily store as much information as the hard disks (HDD) that they can replace.

The more popular sizes of SSDs are 64, 128 and 256 GB and as this technology gets further developed SSD drive capacity will inevitably continue to increase. Also as the price of the NAND Flash memory that they use continues to decrease in price then these drives will continue to become even cheaper.

Because of their solid-state memory, SSDs can be made in smaller sizes than hard disks and they are therefore well suited to mobile computing applications and have already become the standard storage medium for many of the new Netbook computers that have become so popular recently.

Now you can basically take your SSD drive or the computer in which it is installed anywhere you want without the worry of it getting damaged so easily.

Another advantage of the lack of moving parts is that these new solid-state devices need a lot less power and run at much lower temperatures than traditional hard disks, which can generate quite a large amount of heat. Therefore a computer that uses just an SSD for storage will be very quiet and in most cases silent, as a fan will not be required to cool the device, as would be the case for HDD.

At some point in the near future, solid-state drives could replace all current hard disk drives. At present, the prices of SSDs are at a premium as this is still a newish technology. But this will all change as they become more popular and manufacturers and suppliers continue development and start delivering to a mass market.

Access times to data stored on an SSD are much shorter than hard disks, again because there are no delays introduced by any moving parts. This means that solid-state drives are faster than conventional hard drives and this speed increase can be very impressive especially on smaller portable computers.

So, in effect, the new solid-state drives are smaller, more durable, faster, more portable, quieter and use less power than your standard computer hard disk and when the prices drop a little more, which they probably will quite soon, then you will start to see all new notebooks being released with solid-state drives instead of a hard disk drive.
