Up until very recently, people who bought PCs did not have a lot of choice when it came to their laptops and their desktop computer storage devices. Some of the more portable laptops out there have an SSD instead of the normal HDD and just about all of the other drives came with the more familiar HDD. In the modern day, you are able to configure the systems you buy with the devices you want.
Some of the options for a desktop or a laptop come with the choice of either an SSD drive or a HDD, and some of the more expensive ones come with both drives at the same time. So how exactly do you pick the right drive for you? There are many differences between the two, and its important that you know them.
Spinning Hard Drives Used To Be The Only Option
Back in the day, the only option when it came to a hard drive was the one that spun. This was the basic level of storage for any computer, and it was considered very stable indeed. This was also the only non-volatile storage option. This means that when the computer was turned off the data didn’t disappear. Data is stored on a set of metal disks that are placed in the drive. The data is read off the disks in the same way that it is read from a DVD (that’s technology that existed long ago, in the days of cavemen and floppy disk drives). A laser light or a needle reads the data off the disks as they spin at a certain speed. HDDs are ranked based on the speed of the disks, such as 5400rpm or 7200rpm hard drives.
Functions Of SSDs In Comparison
When it comes to an SSD drive the same functions of the hard drive are performed, but in a different way. The data is stored on a series of memory chips that are integrated into the drive. These chips are installed directly onto the motherboard of the computer in the case of the more portable laptops and ultrabooks, or they are placed in a card that can be connected to the computer.
In some cases, they are placed into a box that is able to be installed into the standard hard drive slot of most desktops and laptop computers. They are faster than HDDs by far, and they are a lot more reliable than the similar chips that are used in USB flash drives and other storage media. However, the storage space on an SSD is a lot lower than that of a normal HDD so be sure to pick wisely.
