SSD vs HDD: The Ultimate Comparison


SSD vs HDD: Solid-state drives tend to use less power and increase battery life because data access is much faster and the device is more likely to be idle. Solid-state drives consume half or a third less power than hard drives (typically 2 to 3 W versus 6-7 W). SSDs cut load times and load large files faster, but you won’t notice much of a difference in gameplay between this and a hard drive.


Gamers need a PC drive that can quickly access data, making SSD the best choice for the best gaming experience. Given that data can be read at very high speeds and copied to the storage chip in the solid-state drive, it is natural for computer and storage designers to take full advantage of this capacity.

Technology Used

The advantage of a solid-state drive is that it uses a memory chip instead of a physical spinning disk on the hard drive to access data faster. SSDs perform the same basic functions as hard drives, but data is stored on interconnected flash memory chips, and these chips retain data even if power is not supplied through them. Hard disks use platters to store memory, while SSDs use interconnected flash memory chips and do not require a movable arm/head to read the memory.

With no moving parts, SSDs are more durable, operate at lower temperatures, and use less power. As a result, SSDs have no moving parts, allowing SSDs to be smaller and more durable than spinning hard drives.

Hard drives use magnetism-sensitive platters that are moved by a motor, while SSDs use flash memory with no moving parts, which means they are faster. Hard drives consist of one or more magnetism-sensitive platters, a read/write head drive arm for each drive, and a motor for rotating the platters and moving the levers.

There is also an I / O controller and firmware that tells the hardware what to do and communicates with the rest of the system. These chips are called NAND flash drives, where data is stored, written, and made available to devices.

Solid-state drives use non-volatile NAND flash memory to store files without any flying mechanical parts or magnetic bits, as we see in hard drives. Solid-state drive, on the other hand, has no moving parts, hence solid-state or flash memory. good because the data is stored in memory locations. If you want the fastest computer money can buy, you want a computer with a solid-state drive, although keep in mind that a hard drive is just one component and can be set aside if other internal hardware is not up to par.

While both are used as secondary storage on a computer, an SSD is much better than a hard drive in many ways. While low-cost laptops still come with traditional hard drives (a way for manufacturers to minimize costs), most mid-range and high-end computers come with SSDs. Hard drives are still present in budget and older systems, but solid-state drives are now the rule in traditional systems and high-end laptops like the Apple MacBook Pro, which doesn’t offer a hard drive even as a custom option. In other cases, such as external drives or network drives, hard drives are still popular, although solid-state drive options are expanding rapidly.


SSD vs HDD: Speed Difference

Speed ​​is the main advantage of SSD, it can run faster than HDD-the exact increase in speed depends on what you are currently doing and how you access the data. Speed ​​is also affected by the interface used in the solid-state drive, rather than the hard drive connected to the rest of the computer system when transferring data back and forth. HDD / SATA drives have different speeds, which will affect the transfer speed.

SSD and HDD speeds are measured in MB / s (megabytes per second) both when reading (how fast the disk can read data) and writing (how fast data can be written to the disk). To demonstrate the difference in speed between HDD and SSD, compare the benchmarks below (using CrystalDiskMark).

SSD vs HDD: Price and Peformance

When comparing hard disk drives and solid-state drives, the main difference is price and performance. Even the best solid-state drives cost 9 cents or more per GB, while hard disk drives cost less than 2 cents per GB. The price of a GB SSD can easily be twice the price of a hard disk, and for a high-performance SSD, it cost maybe three times or more than that of a hard disk. Although prices have been declining over the years, the cost per GB of solid-state drives is still higher than that of hard-disk drives.

With a similar amount of storage, you might end up paying almost twice the cost of a hard drive for an SSD, or even higher capacity. Although you pay a higher price for using SSDs for less space, in general, you are investing in faster, more efficient, and more durable storage.

If, on the other hand, you can bundle your system with more drives, you can get the best of both worlds by using a smaller SSD as your primary drive and a much more spacious but inexpensive HDD as your backup drive. You could probably use any combination of these drives to create your storage system; However, the best choice for most users is a small SSD paired with a large HDD. Some computers use a small solid-state drive that has an operating system installed, as well as a hard drive for shared storage because the boot times are much faster with solid-state technology.

Storage Space

Newer and faster solid-state drives generally have less storage space than hard disk drives. NVMe SSDs typically have capacities up to 2TB, and commercial drives up to 8TB. Generally, SSDs can handle more than 1000TB, and most people will never come close to using them, but the limitations still exist and are worth considering.

Since NVIDIA ShadowPlay technology is constantly recording data, if you burn scratch discs with these recordings to a solid-state drive, the recording time of discs will be shortened faster. Hard drives don’t have the same length limits, so you can essentially write any data to the hard drive without any real impact, making the hard drive a better option for programs like ShadowPlay. Hard drives are still a very useful setup option when you want to store large amounts of data in a context where the speed of the drive’s write and read speed is irrelevant. And if you need to drastically free up space, you can easily format any hard drive, internal or external, whether it’s a hard drive or an SSD.


This means you can get a relatively affordable SSD, especially if you are willing to accept the more mediocre speeds of 2.5-inch SATA-based drives. Even if you prefer a more compact M.2 SSD, you can still find a compatible drive that uses a cheaper SATA interface instead of NVMe. Although the price difference per GB between hard drives and low-end SSDs has narrowed, the additional funding for SSDs may cause your system to exceed your budget.
