Discovering The Truth About Data

5 Things to Consider Before Purchasing a Hard Drive

A hard drive is a vital component in any modern computer. It’s recommended that you buy a new drive every couple of years, to replace an old one or use as an extra hard drive. But which hard drive do you pick, with so many options available?

The best thing about shopping for hard drives is that it’s not that difficult. As long as you stick to the following guidelines, you’ll not have to worry about getting the wrong drive or something like that.

The Beginners Guide To Data (From Step 1)

The very first point to take into account is whether you prefer a solid state drive (SSD) or not. Although an SSD functions just like a HDD (hard disk drive), it comes with its own pros and cons.

So, how is an SSD different from an HDD?

First, solid state drives read and write information faster. Secondly, SSDs need less power, conserving energy and lengthening the battery life of a laptop. Thirdly, as SSDs don’t have moving parts, they don’t make noise and are more durable. The drawback is that they have small storage space and are more expensive than HDDs.

What matters more? If price is an issue or you just want a backup drive, buy a traditional HDD. But if the computer hard drive will run an OS or hold plenty of frequently-accessed files as well as programs, particularly video games, then opt for an SSD instead.

Interface and size

After you’ve picked between a HDD and SSD, you’ll need to pick a form factor. Fortunately, there are just two options and your current setup will determine your choice. 2.5 and 3.5-inch drives are the two form factors.

Desktop HDDs are typically 3.5 inches and laptop HDDs are 2.5 inches. In contrast, SSDs are even smaller as they don’t need moving parts. So, most SSDs are typically 2.5 inches.

Specs and performance

In terms of data volume, there are all sizes of HDDs, with storage capacity limited to 4TB because of physical restrictions. In contrast, SSDs are far much smaller, with their storage capacity capped at 1TB. Even so, many SSDs hardly exceed 512 GB.

Many factors determine the performance of a hard disk drive, but one important factor is revolutions per minute, or RPMs. The lower the RPMs, the slower the data transfer.


There are various prices for computer drives that really look the same on the outside. It’s your responsibility to decide on factors that are essential to your needs as well as drives that fit your parameters.

Internal versus external

The last factor to consider is where your drive will be housed. Will it be housed within the casing? Will it be used outside? Either way, what you choose will be determined by your needs and preferences.
