Computer Hard Drives: 5 Things to Consider Before Buying One
Hard drives are crucial components of modern computers. It’s recommended to buy a new drive every few years, to use it as an extra hard drive or replace an old one. However, with so many options available, which one do you choose?
The best news about shopping for computer hard drives is that it’s not at all difficult to choose. Provided you follow the guidelines below, you won’t have to deal with getting the wrong drive or anything of the kind.
SSD vs. HDD
What You Should Know About Data This Year
The very first point to take into account is whether you prefer a solid state drive (SSD) or not. While a solid state drive has the same function as a hard drive, it comes with its own advantages and disadvantages.
What Research About Reviews Can Teach You
So, what are the differences between an HDD and SSD?
First, SSDs read and write data faster. Secondly, SSDs need less power, conserving energy and lengthening the battery life of a laptop. Thirdly, with no moving parts, SSDs don’t make noise and last longer. The disadvantage is that they come with less storage space and are costlier than HDDs.
What is more important? If you just need a backup drive or price’s an issue, go for a traditional HDD. But if the drive will launch an operating system or contain numerous frequently-accessed files and applications, especially video games, choose an SSD instead.
Interface and size
After you’ve picked between a HDD and SSD, you’ll need to pick a form factor. Luckily, there are only two options and your choice will depend on your current setup. The two form factors are the 2.5-inch drive and 3.5-inch drive.
Desktop HDDs are typically 3.5 inches and laptop HDDs are 2.5 inches. SSDs, on the other hand, are much smaller since they do not require moving parts. So, most SSDs are typically 2.5 inches.
Performance and specifications
In terms of storage capacity, HDDs are available in all sizes, and storage capacity is capped at 4TB because of physical limitations. SSDs, on the other hand, are far smaller and the storage capacity doesn’t go beyond 1TB. Despite that, many SDDs rarely exceed 512GB.
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 many different prices for drives that have the same physical appearance. It’s your call to choose which factors matter to your requirements and to choose a drive that suits those parameters.
External vs. internal
The last point to take into account is where the computer drive will be housed. Will it be housed inside the casing? Will it be used outside? Either way, your choice will depend on your needs and preferences.
