Difference Between RAM and Hard Drive

Random Access Memory (RAM) and Hard Drive (HDD) are ii types of estimator retentivity used to concord instructions or information. The RAM is, however, temporary storage whereas HDD is the permanent computer storage. Both are physical components of the calculator used to store information, except RAM is a volatile memory and HDD is a non-volatile memory. We take a wait at some key differences between the ii.

What is RAM?

Random Access Retention, commonly goes by RAM, is essentially short-term data storage which stores the information as the processor needs it. RAM almost allows instant access to data; when a program is fired up, it is stored temporarily in RAM for easy access, equally opposed to beingness stored in the permanent storage such every bit a difficult drive. RAM is a volatile memory that stores instructions and data of currently running programs, and the data is lost once the power is lost. This means it requires power to store the information which gets erased when the ability goes off. Information technology simply maintains the data when the device is on. It is typically used to shop working data and machine lawmaking. Every fourth dimension yous play a game or stream a movie online, the information is stored temporarily in the RAM, so that the processor can access it instantly. Once the process is closed, the data is erased, making way for the adjacent task.

What is a Hard Drive?

Hard drive (HDD) is an electro-mechanical storage device that plays an important role in the modern era of digital technology. HDD is the master data storage hardware device in a computer that has spinning disks inside where the data is stored magnetically. HDDs sit in the heart of the storage pyramid, between the semiconductor memories and removable drives. Unlike RAM, it is a non-volatile memory that stores all your digital content and data on computers, such as pictures, videos, documents, music, programs, and applications. The HDD manufacture has a relatively short but fascinating history. In the past six decades information technology evolved from a gigantic 24-inch diameter disks storing merely 5 MB of data to modern mean solar day SSDs storing up to a whopping 100 TB of data in a portable like shooting fish in a barrel-to-comport class factor. HDDs come up in internal and external grade factors.

Departure between RAM and Hard Bulldoze

Memory Blazon

 – RAM is a volatile retentiveness that stores instructions and data of currently running programs, meaning it requires power to store the information which gets erased when the power goes off. Information technology only maintains the information when the device is on. Hard drive (HDD), on the other hand, is a blazon of non-volatile memory that has the capacity to retain saved information even if the power is turned off. Dissimilar RAM, it does non require a continuous ability supply to retain the stored information.


 – RAM is a short-term data storage device that stores the information or instructions that the estimator is using actively so that the processor tin instantly admission it when required. It is typically used to store working data and machine code. Programs that are currently running and the opened files are stored in RAM. HDD, on the other paw, is a permanent storage device that stores all your digital content and data, such equally pictures, videos, documents, music, programs, and applications on reckoner.

Form Factor

 –RAM mainly comes in two sizes: DIMM (Dual In-Line Retentiveness Module) which is plant in desktops and servers and And then-DIMM (Pocket-sized Outline DIMM) which is for laptops. Both the form factors utilize the aforementioned engineering and work nearly the same manner, just the two cannot be used interchangeably. HDDs come up in two main form factors: 3.5inch drive which goes inside desktop computers and 2.5-inch for laptops. HDDs can be either IDE or SATA.


 – RAM is typically much faster than other storage devices including HDDs because OS, applications, such as a web browser, MS Discussion, etc., or a game are stored in the RAM temporarily, then they are to be accessed near instantly by the processor. HDDs are high-storage devices that operate in the range of five,400 RPM to x,000 RPM, with most desktop HDDs running at the standard vii,200 RPM. The speed and performance of your computer is attributed to its RAM chapters, not the HDD.

RAM vs. HDD: Comparison Nautical chart


Both RAM and HDD are physical components of a computer used to hold instructions or data in a computer retention. This is where the similarities end. RAM is a volatile memory that stores the information as the processor needs it, and so that the processor could access information technology well-nigh instantly without whatever delay. However, the information is lost when the device is turned off or the machine loses power. This is not the case with HDDs, which have the capacity to retain power even if the device loses ability. HDDs are permanent storage devices used to store all your digital content and information on the computer.

Is RAM same as hard bulldoze?

RAM is a temporary memory which mainly stores instructions or data every bit the processor needs it, whereas a hard drive is the main data storage hardware device in a estimator that stores information or data permanently. RAM is a volatile retention while HDD is a non-volatile memory.

Is RAM or hard bulldoze more important?

Both are important physical components of a computer that play a pregnant role in the proper functioning of a computer. More RAM means you tin can run more than complex programs simultaneously without slowing your computer down. More HDD storage means you can store more things on your reckoner.

What is ameliorate more RAM or bigger hard drive?

More RAM means better processing, which means more specialized work without slowing your machine down. Bigger hard bulldoze means more storage.

Is eight GB RAM and 256 GB SSD enough?

Yes, it is enough for all your programs and 24-hour interval-to-day work. However, if you want to play lots of graphics-demanding games or you have a lots of media collections, you probably demand more than RAM and more storage capacity.
