If you've bought an ultra-portable laptop in the last few years, you've likely adopted a solid-state drive (SSD) as your primary boot drive. Larger gaming laptops have also moved to SSD boot drives, while only a small percentage of budget machines still favor hard disk drive (HDD).

But if you could only choose one, how would you choose? Let's dive into the differences between the SSD and HDD and walk you through the pros and cons of each to help you make your decision.



In terms of dollars per GB, SSD is more expensive than hard drives. 1TB internal 2.5-inch HDD costs between $40 and $60, and SSD of the same capacity and form factor now starts at around $100. If you look at high-capacity 3.5-inch hard drives, the difference is even more pronounced.

Since hard drives use older, more mature technology, they will likely remain less expensive for the foreseeable future.



This is where SSD excels. A PC with an SSD will boot in less than a minute, usually just a few seconds. An HDD takes time to accelerate to operating specifications and it will continue to be slower than an SSD during normal use. SSD-equipped PCs boot faster, start and run applications faster, and transfer files faster.


Form Factor

Because hard disk drives rely on spinning platters, they are always limited by size. The SSD has no such limitations, so they can continue to shrink over time. However, they are increasingly moving to M.2 form factors, and these drives are available in lengths of 42 mm, 60 mm, 80 mm and 120 mm.


Reliability and Durability

SSDs have no moving parts, so it's more likely to keep your data safe if you drop your laptop bag or if your system gets jolted while it's running. Heat is a major cause of hard drive failure, and the constant movement of a hard drive's moving parts generates enough heat to cause it to break down over time. Because an SSD has no such parts, they can maintain lower temperatures and have higher performance.


Common Capacities

The consumer SSD with capacities over 2TB is rare and expensive. While 500GB is considered the base hard drive capacity for high-end laptops today, pricing issues may push it down to 128GB or 256GB for less expensive SSD-based systems. basically, the larger the storage capacity, the more content you can keep on your PC.



An SSD does not have to consume power to spin the platters from rest. As a result, the energy consumed by SSD is not wasted due to friction or noise, which increases their efficiency. On a desktop or server, this reduces energy costs.

Energy efficiency is a big advantage of using SSD for PCs and mobile devices where battery life is a highly marketable and in-demand feature.
