The Differences Between HDD And SSD Memory!

A critical component which is known by two types of HDD and SSD memory is required to store information and any data in the system; In following; we are going to compare two types of memory storage, namely HDD memory and SSD memory, and also Compare and define each other; Stay tuned to Technelo.

Description Of HDD And SSD Memory Storage

HDD Memory Storage

HDD stands for “Hard Disk Drive,” which refers to a traditional hard disk drive, which is the local HDD for storing operating system files, folders, and your information. In general, the hard disk consists of a circular disk with the help of a read and write head; Information is read or written from it.

Faster disk rotation on the HDD makes it faster to transfer data to external memory or speeds up data read and write.

SSD Memory Storage

SSD stands for Solid State Drive; it can be said that SSD is a more advanced version with larger dimensions of flash memory, and unlike HDD, there are no moving parts in SSDs; In SSD storage devices, information is stored on microchips, which means that the SSD has no moving part and instead the moving part will be done by NAND memory.

Comparing HDD And SSD Memory; Step By Step

  1. SPEED
  4. PRICE
  7. Noise And Lifespan

we can compare SSD and HDD in various aspects such as speed, price, capacity, and size. Is often, the price is the most important factor when buying memory. Most importantly, however, we should not compare it only in price; It is necessary to check all aspects when purchasing. Let’s see how are the differences between SSD and HDD memory!


Unlike the HDD, there is no movement on the SSD, and the speed of the SSD does not depend on the number of revolutions per minute or RPM. Rather, the technology used and the support of the desired connection will determine its speed. It is good to know that an SSD with a SATA III connection can read data from a disk at a speed of 550 MB / s or write data to memory at a speed of 520 MB / s.

Also, the loading speed of Windows and the speed of data exchange in a system where the Windows drive is connected to the SSD is 40% faster than when the HDD memory drive is connected to it.
The same is true in games; Game loading speed will be faster when the SSD drive is connected to the drive to which the game is connected; when the HDD drive is connected to it; Even with SSD gaming memory, they are so fast that loading makes no sense.


In terms of capacity, the SSD has two models with a capacity of 1 terabyte for laptops and finally 2 terabytes for desktops, in contrast, the HDD has more capacity and two models of it have a capacity of 500 GB and 2 terabytes for computers. And for desktops, this amount is equal to 6 terabytes.


In the security sector, it is possible to fully encrypt both SSD and HDD memory, but HDD memory is not resistant to magnetic effects and the information in the memory may be erased, but SSD is resistant to magnetic effects, also; If you erase the data on the SSD, you will not be able to recover the data, but on the HDD, you can recover the data to some extent.


If you want to buy a 1TB SSD, for example, you have to pay about $ 200 to buy it, but in return; To buy HDD memory with the same capacity of 1 terabyte, you can get it at a lower cost of about $ 100. Expensive SSDs compared to HDDs are also one of its disadvantages.


In HDDs, due to the moving and sensitive part called the head and plotter, with the slightest impact and slip and shake, they are especially vulnerable while working, but in SSDs this problem is solved and generally a technology Another is used, which is close to flash technology or so-called NAND, in which there is no moving part inside and they are almost shockproof and information is stored in ICs.

Power Consumption

Power consumption is different in both and in this part, SSD memory works better than HDD memory and produces less power consumption; HDDs consume 6w, but power consumption in SSDswill be 4w, sometimes reaches as much as 2w too.

Noise And Lifespan

SSDs have a lifespan of 2 million hours, but HDDs have a lifespan of 1.5 million hours; Also, HDDs make a lot of noise, but SSDs can be used without making any noise.

Can We Use Both SSD And HDD Memory In The System?

Show two with one arrow! You can use both HDD and SSD memory, but what do you intend to do? If you want to increase the speed of the system and do your office work faster, you need to connect the SSD to your Windows drive, that is, install your Windows on the SSD drive, and in addition, an HDD hard drive can also have More memory to help you store large, online files.

But if you want to have these two memories together because of the game, it is recommended to buy an SSD gaming first, because the speed of SSD gaming is higher than ordinary SSD and can increase the loading speed faster than ordinary SSDs. without SSD you will have; Slow and no longer bother with long loads, in addition to SSD, having an HDD can also be effective for storing large files.
Note that most HDDs are popular because of their high and cheap memory, and SSDs are also popular for their high-speed performance.

Having a system with only SSD memory or vice versa having a system with only HDD memory can be to your detriment; If you do not have SSD memory, you should be concerned about the speed of our system in sending and receiving files or long loading of Windows; On the other hand, if you only use SSD memory, you can not have all your files and use them, however; If you want to have more SSD memory in the system to be able to access all your files, You have to pay a high price that does not seem like a lot of wise work.
