The first-ever hard disk drive was developed in 1956 and held no more than 5MB of data.

With modern computer technologies changing so quickly, it can be difficult to keep up with them and the constantly shifting terminology.

If you are wondering which storage technology is the best for you, then fear not for we have compiled this hard drive disk guide just for you.

Read on to find out which type of drive you need for your home or work PC.

What is an HDD?

HDD stands for Hard Disk Drive and is a data storage device that you will find inside most computers. It is a legacy technology that has been around for many years since the development of the personal computer.

Data is stored magnetically on several spinning disks inside the caddy. The drive is connected to the computer’s motherboard so that your processor can read the data stored on the disk.

What is an SDD?

SDD stands for Solid State Drive and is a data storage device with no moving parts. Instead of being stored on spinning disks, data is actually stored in integrated circuits.

This enables their design to be much smaller and more efficient than their HDD counterparts. The memory stick is a good example of the first solid-state drives on the market.

The Main Differences Between HDD vs. SDD

As a traditional storage device, HDD is much slower to read and write data than SDDs. They are also noisier as the physical parts have to move to read and write files.

SDDs come in various sizes but are often 2.5 inches in size when used in a PC. SDDs are much faster when used as the primary boot drive.

SDDs are more expensive per gigabyte than HDDs. You can buy far more GBs of storage space in an HDD for much less expense. However, this price gap is closing.

Traditionally people tend to install a small SDD for quick boot access and to access files and applications they need quickly. This is especially true for gamers who play online who need their games to be extremely responsive.

On the other hand, HDDs are preferred by video editors or people who require large amounts of data stored on their PC but do not need fast response times.

Storage Technology and Data Recovery

HDDs tend to be susceptible to data loss and a need for data recovery than SDDs due to their more fragile design. Dropping an SDD is likely to cause minimal damage, whereas dropping a hard disk drive could result in major data loss.

Whichever type of drive you choose for storing data, you need to be sure that you can recover your data quickly and easily. Using a service like hard drive data recovery from Lifeguard can give you the confidence you need that your data can be restored.


Hopefully, this guide has given you some insight into which storage technology will be best for you. Choose a hard drive that best suits your needs depending on whether you require fast speeds or GBs of space.
