Going to buy a new laptop or PC or want to upgrade your computer? thinking which one to buy whether SSD or HDD? SSD is termed as solid-state drive while HDD is termed as hard disk drives. budget computers offer hard disk drives (HDD) while high-performance computer offers solid-state drive (SSD) Choosing SSD or HDD totally depends upon performance, power usage, and reliability.SSDs are much more expensive than HDD. Most of the laptops and computers come with the support of both HDD and SSD. Here we have a complete comparison of SSD VS HDD in terms of price, capacity, Reliability, and Lifespan.

What Solid State Drive(SSD)?

SSD is a solid-state drive with no moving parts that hold data on flash memory. The SSD has semiconductor cells. A basic memory chip is used called NAND flash memory. SSD memory chips are similar to random access memory ( RAM). Data are stored on a grid of NAND flash cells instead of a magnetic plate. Each grid of SSD can store between 256 KB and 4 MB. The SSD controller has the exact address of the blocks, so that it is (almost) immediately accessible when your PC requests a file. There is no waiting for the read/write head to discover the knowledge it wants. SSD response times are therefore calculated in nanoseconds.

What is Hard Disk Drive(HDD)?

HDD has rotating discs inside which data is stored magnetically. The disc spins, causing the read-write arm to read data on the disc (or write data on it) while the disc spins. The more the disc spins, the more the hard disc performs. Arms have many transducers that read and write disc files. Both sections of HDD are mechanical, the hard disc is the slowest and most vulnerable portion of any computer.




The power of the drives is to equate SSDs and HDDs. Generally, if you’re looking for a lot more storage space, HDD is far better than SSDs. HDD size ranges from 40 GB to 12 TB, there’s much more size for corporate. You buy a 1-2 TB hard drive at a reasonable price, which allows you plenty of space when you compare with SSDs. HDDs also come in a large size of 8 TB to 12 TB.HDDs are suitable for storing a lot of huge files, which makes them ideal for keeping images, videos, and games. SSDs were usually not capable of such high volumes, however, due to technical advancements, you can now have SSDs with terabytes of capacity. But the cost of SSDs is much more if you compare with SSDs.


hdd vs ssd speed

As far as speed SSDs are concerned, the success of SSDs is growing day by day due to their speed. SSD’s are both electronic components and do not have any actually moving parts like HDD.SSD and HDD speeds are calculated in MB / s for both reads and write data. there are many other variables that decide HDD speeds, such as capacity, an average the SATA III HDD operates at 5,400 RPM will have speeds of about 100MB/transfer speed, while a 7,200 RPM HDD will have 150MB / s. Because SSDs do not have any moving parts, their speeds will not be decreased. But on the technology – and network link – of the drive.

The traditional hard disk takes around, 30-150 MB per second (MB / s), where the same operation takes about 500 MB / s on a standard SSD, or even 3,000-3,500 MB / s. Much of the time, when you run Windows open applications, or search the web, you simply open and access thousands of smaller files that are contained in tiny data blocks. The better your disc can read (and write) these 4 K blocks, the better the machine tends to be. The pace for HDDs varies from 0.1 to 1.7 megabytes per second (MB / s). However, SSDs and NVME SSDs run at a much higher rate of 50-250 MB / s in 4 K reads/writes. Simultaneous readings are about 56 times faster (fifty-six times faster!) and small 4 K read operations are about 226 times faster.


SSD and HDD, the first major difference you’ll find is the pricing. SSDs are normally more costly if you compare with standard hard disks. Some SSDs are more costly than normal SSD. Older SATA III SSDs are cheaper than M2 and PCIe SSDs, and since the hardware has been around for a while, some SATA III SSDs are really not that costly than standard hard drives. If you want the most space for the least money, the HDDs are far better. A 500 GB Hard disk costs between $25 to $50 while a500 GB SSD from about $60 to $150.


If you are a hardcore gamer then SSD is better for you because it loads and plays games faster. Video games contain large quantities of assets, such as high-resolution graphics, models, music, and more If you run GTA V on SSD it takes 25 seconds longer than HDD. While the HDD takes about two minutes, you’ll experience reduced stutter while playing games, since the rest of your PC will not have to wait for the game data to be loaded while using SSD.



SSDs are generally more reliable than HDDs, which again has the benefit of having no moving parts. This is because, without any moving part, SSDs are not impacted by shaking or associated thermal problems. SSDs commonly consume less power which leads to much better battery life in your laptops because data access is much smoother and the system is most often idle. HDDs need more power as they have moving parts and are volatile if by mistake you fall them.
