External Hard Drive Buying Guide

Types of Storage Devices

There are several different types of external hard drives including:

  • Desktop – External desktop hard drives are designed to be used with your standard desktop computer where it will normally stay in one place although it can be moved. This type of drive usually has more storage capacity and is cheaper per GB of storage, but it is also larger in size and will usually have a separate power adapter.
  • Portable – Portable external hard drives are normally meant to be used with laptops or any computer where you need to the ability to easily transport the storage device. They are smaller and are normally powered by a USB cable, but are usually more expensive per GB of storage than desktop models.
  • Wireless – Wireless external hard drives are portable units that provide an onboard Wi-Fi connection so you do not need a cord to connect to your device when transferring files. Wireless storage expanders are especially useful with tablets where you have a limited internal storage capacity, but you would still like to have your entire video and music collection with you.
  • Network Attached Storage – A network attached storage (NAS) device connects to a network instead of an individual computer and acts as a shared drive for backing up data and sharing files across your entire network. Some of these units provide advanced features like media streaming and you can find models with multiple drives that allow for more capacity and greater protection for data. These are much more expensive and larger than a typical external drive.
  • SSD (Solid State Drive) – SSD is a type of hard drive. It offers much faster performance and reliability, but also costs a lot more than average and usually has much less capacity. It is recommended for anyone who needs faster transfer speeds or who wants less of a chance of failure since it has no moving parts.

Storage Capacity

In simple terms storage capacity is how much data your drive can hold as measured in gigabytes (GB) or terabytes (TB). 1 TB is equal to 1000 GB. Current external hard drives range from about 250 GB up to 4 TB or more. Users who have a large video or music library probably will want at least 1 TB to 2 TB. If you don’t have a lot of media files to hold, you can get away with a drive having less storage. If you are backing up your data, you should get a drive with at least as much capacity as your internal hard drive on your computer.

Transfer Speed

The transfer speed is how fast data can transfer to and from the device as measured in Megabits per second (Mbps), Megabytes per second (MB/s) or Gbps (Gigabits per second). 1000 Mbps is equal to 1 Gbps. The more often you backup or transfer files, the more of a priority should be placed on the speed. There are several different connectors and interfaces that determine how fast your unit is and the external drive and computer must have compatible connectors to maximize speed.

  • Thunderbolt 3 – 40 Gbps
  • Thunderbolt 2 – 20 Gbps
  • Thunderbolt – 10 Gbps
  • USB 3.1 Gen 2 – 10 Gbps
  • USB 3.1 Gen 1 (USB 3.0) – 4.8 Gbps
  • USB 2.0 – .48 Gbps

A Thunderbolt 3 connector is the fastest connection available at up to 40 Gbps, but is also the most expensive and not as widely used. USB 3.1 Gen 2 is the fastest USB connector at 10 Gbps. USB 2.0 will be the cheapest, but has the slowest speeds of 480 Mbps. If your drive has a USB 3.0 connector, but your computer is only USB 2.0 compatible, then the speed of transfer is only at the USB 2.0 speed.

Portability

Getting a small, portable unit is advisable if you need to transport your drive constantly. Smaller models cost more, but some are small enough to fit in a pocket. Make sure you also get one that is powered by the data cable so you do not have to have an outlet.

Durability

Hard disk drives (HDD) are more prone to shocks, vibrations, moisture, and heat than SSDs. Some units come with cases that provide physical layers of protection for the drive in case you drop it or to protect it from heat and moisture. If you work in in a rough environment then one of these models might be for you.

Compatibility

Many units are built for use with either the Apple ecosystem or for PC’s. These will work right out of the box for you with the correct hardware. Some models will work with any hardware, but may require you to reformat the drive before using it with a specific internal hard drive. Make sure the storage device you buy is compatible with your operating system.
