Hard Drive

The hard drive stores all the user and working data—whilst, here the simple thumb rule is, more the capacity in the hard drive, the more will be the burden on the budget. Without diving into technicality, there are typically two types of storing units in the industry till today, solid-state drive and hard disk drive . These are explained as;

HDD—Economical, but Slower than SSD

The HDD has its root from the 1950s firstly introduced by IBM—thus, the technology is old and slow. The pro side of using the HDD is its larger capacity and affordability. On the other hand, they take a lot of space and a bit slower. They usually have a sustained transfer rate of around 200 MBps. As for your cheap gaming pc under 300, they can be the cheapest mass storage option.

SSD—Faster, but Pricier than HDD

The SSD (solid-state drive) has smaller dimensions of only 2.5 inches form factor—the data processing speed is a lot faster, up to 550 MBps in the latest models. Also, SSDs store data differently without having moving parts, rather than storing the data on the integrated circuits. This leads to faster booting and loading of the game. As, because of these advantages, the SSDs are a bit pricier than the HDDs.


Both of the drives have a different capable range of storage—although, the storage capability for HDD is going from 512 GB to 15 TB. On the other hand, the SSD ranges up to 1 TB. For the cheap gaming pc under 300, the SSD is eligible for boosting the capability and performance. As for the SSD, because of being ultimately fast and less heating extent, they are better and preferable.
