Advantages And Disadvantages Of External Hard Disk Drives




Geek Square computer repair technicians in Toronto area often do get asked what the advantages and disadvantages of external hard disk drives are. In this article, we will explain what an external hard disk drive is and what are its advantages and disadvantages.

A portable storage device that can be attached to a computer through a USB or FireWire connection, or wirelessly is called external hard disk drive. These drives have high storage capacities and are often used to back up computers or serve as a network drive.

External HDDs can range from about 2GB to 4TB. Some drive companies put two 4TB drives in one chassis creating an 8TB HDD, which is total overkill for most people. For example, computers these days usually come with anywhere between about 250GB and 750GB of space in the hard drive.

Here we are going to discuss some advantages and disadvantages of external hard disk drives.

Advantages & Disadvantages Of External Hard Disk Drives

Advantages:

1- External hard drive is portable and operates on a plug and play basis. We can use it as a storage device for any computer with a USB or FireWire capability.

2- You can use an external hard as an emergency backup drive. Sometimes hard drives crash, so having a backup is essential if you depend on your computer for work or personal needs.

3- If you use the external drive as your main drive, you can speed up the performance of Macs with slower internal drives.

Disadvantages:

1- External drives have the same data loss risks as internal drives. External hard drives can get attacked by viruses, worms, and malware software. They can also be affected by sunlight, heat, humidity, liquids, dust, and magnetic fields.

2- Most external hard drives have no password. If your hard drive or flash drive is lost or stolen, your information is available to anyone who plugs the device into a computer.

3- File versioning is challenging to set up on external hard drives. If you back up to an external hard drive once per day, you’re often left with a single backup to rely on instead of multiple file versions.
