Solid State Drives


Solid State Drives

Also known as solid state disks, these drives are data storage devices the make use of integrated circuits (IC) as the primary form of data storage. In case you do not know, the conventional storage devices of these days (Hard Disk Drives) make use of magnetic disks. Compared to them, SSDs are generally less susceptible to physical shock, they are more silent, and perform at a lower access time and latency.

How do Solid State Drives Work?

In the simplest terms, the key parts of SSDs are the controller and the memory. The controller incorporates all the stuff and makes sure all the components are bridged from the memory to the host computer. The memory functions as the storage area.


Why Use Solid State Drives

There are many advantages of using solid state drives, and outlined below are the most important of them. These factors are compared with the conventional hard disk drives (HDD).

Start Up

Compared to HDDs, the start-up time of 256GB SSD is almost instantaneous. HDDs require (up to minute) of disk spin-up, hence it is clear that SSDs are much better in terms of this factor.

Access Time

The access time of HDDs ranges from 2 to 3 ms, due to the need to wait for mechanical parts to rotate. SSDs on the other hand are almost instantaneous.

Data Transfer Rate

Common SSDs available in the market has around 100 MB/s to 600 MB/s transfer rates. Enterprise level SSDs have even much higher. As for HDDs, the average transfer rate is 140 MB/s, which of course also depends on the hardware.

Susceptibility to Damages

HDDs are composed of mechanical and magnetic parts, and are likely to be damaged when exposed to strong magnets or even just by dropping them. SSDs on the other hand make use of circuits, and so except for intended damaging, SSDs are less likely to be dysfunctional upon falls and other cause of physical damage.


Though HDDs are relatively cheaper to SSDs, the price of SSDs in the market is already going down, and so time will come when SSDs will then par with the price of HDDs.

What to Look For When Buying Solid State Drives

If you’ve decided to get a SSD as the primary storage drive for your data, obviously there are lots of things you should watch out for. Outlined below are the most important of them:

  1. Buy only from a reputable company. There are lots of faked stuff in the electronics market, and therefore you should always watch out for them. Better yet, just buy from reputable companies, as their product will be most likely of quality.
  2. Determine your data storage needs. What are you planning to store? This will also matter as purchasing SSDs that are very large in storage space obviously will cost you more.

Best Solid State Drives

One of the best 256 GB SSD available in the market is the Crucial M4 CT256M4SSD2 256GB SSD. It’s a lot better as it is designed for cloud computing and is very small and lightweight.
