Best Internal Hard Drives – Both Laptop 2.5” and Desktop 3.5” HDD – 2017


Last updated: March 26, 2017

If you are looking for the best internal hard drive, then you have found the answer. I do realize that most of you have very busy schedules and have no time to read long reviews, and that is the reason why we made the list below. Our guide includes hard drives with the best price per GB ratio, combined with speed, warranty, reliability and customer reviews. So you can easily find the best hard drives for your needs, saving a lot of time and money at the same time.

Nowadays it can be very frustrating for a non-expert in hard drives and storage devices to find the best hard drive. After long hours of hard drive tests and research, we determined that the Seagate FireCuda Gaming SSHD is the best hard drive for a laptop on the market, at the moment. It is Solid State Hybrid drive that offers both performance and capacity for a low price. In last years, our need for a bigger storage device is growing rapidly and drives must be much faster and more reliable to manage all that data. Solid State Drives, also known as SSD are the fastest ones, but they are also much more expensive and with lower capacity than mechanical hard discs.

It is very hard to determine top pick from 3.5-inch desktop hard drives, because of their vast diversity. Some of them are manufactured for NAS, some for backup or surveillance systems. To find the best 3.5-inch hard drive, you definitely must know where you will put it and use it. 

How to choose between SSD, SSHD and HDD?

It depends on your situation, purpose, budget and whether you have a Laptop or PC. No doubt, if you have a laptop, you need to look at SSD or SSHD if you don`t want to spend a lot of money then you should buy SSHD. Solid State Hybrid Drives are faster than mechanical hard drives, but they will cost you almost the same money as internal hard disc drives. If you don`t care so much about the money and it`s all about speed, then a Solid State Drive is for you.

For example, 1TB HDD or SSHD drives will cost quite below $100, but the price for a 1TB SSD will be more than $300, that`s a big difference. Also, you need to find out more about your laptop, because if your laptop uses IDE, then you need IDE to SATA. All SSD will work on any laptop that is using an SATA drive connection. On some laptops, you can install both HDD and SSD because they have a place for two drives. Combining both HDD and SSD is the best option to increase performance, capacity and to save as much money as possible. 

Use two drives – SSD and HDD on desktop computer to increase performance and capacity

The same applies if you have a personal computer, then you should combine two types of hard drives – SSD and HDD. You can install your operating system on the SSD and store all your movies, music and pictures on a much bigger HDD drive. By doing that, you will have the superior speed of SSD and plenty of capacity from the HDD. Overall you get faster boot times, faster program and game launches.

It is a good idea to read through Amazon customer reviews, where you can find a lot of very useful information about the drive you have chosen to buy. To find the most reliable internal hard drive in the long term we looked at Backblaze data and other similar sources. Cloud Backup companies can offer a massive amount of hard drive reliability data because they have thousands of hard drives running non-stop all the time. In the list below you can see the top best internal hard drives, for both laptop and desktop computers.
