SSD vs. HDD
Whether you're considering a new PC or looking for an additional external hard drive to back up your files, you want to be sure your important data will be secure. Hard disk drives (HDDs) operate using a spinning disk, while solid state drives (SSDs) do not have any moving parts. SSDs and HDDs are both readily available on the market, so you'll want to consider the unique advantages of each type of drive before you buy.

Solid State Drive
Advantages of SSD storage
- Very Durable - No moving parts, like a spinning internal disc, means nothing will be damaged if your device is dropped or bumped while carrying it.
- Quiet - Since there are no spinning parts, there is no noise or vibration produced when the SSD operates.
Limitations of SSD Storage
- Expensive - SSD is a pricier form of storage, so getting a large-capacity drive can be cost-prohibitive.
- Lower Capacity - Currently, most internal and external SSDs are smaller than comparably priced HDDs. SSDs up to 1 TB and even higher are available, but cost many times the price of a HDD with the same capacity.
Hard Disk Drive
Advantages of HDD storage
- Inexpensive - HDDs are an older technology, so you can obtain a new drive or a spare one to use as a backup at very reasonable prices.
- High Capacity - HDDs are readily available even in the range of 1-3 terabytes (TB) and beyond.
Limitations of HDD storage
- Less Durable - While reliable for home use on a desktop PC, HDDs use spinning disks that are vulnerable to the shocks and impacts that can occur when carrying and using a portable device.
- Noise and Vibration - Due to their moving parts, HDDs can produce more sound that can be a nuisance as you try to work at the computer.
