Difference Between Hard Drive and Memory

Hard Drive and Memory are both used to store data. There is an error of messages which pops on the screen, which indicates that the memory is full, but mistakenly, it is considered that the hard drive is full. The size of the memory is smaller than the RAM. Hard Drive can store more capacity.

Hard Drive vs Memory

The difference between Hard Drive and memory is Hard Drive has permanent storage, but Memory does not have permanent storage. It has temporary storage. Hard Drive consists of platters, but chips are used to form memory. The memory stores the whole information in binary language. The power supply is needed by the memory, not the Hard Drive.

Hard Drive is made by using platters. The storage capability is permanent. This is a collection of hard disks. The capacity is huge in Hard drive. The speed of access is low on a hard drive. Hard Drive does not need a power supply continuously. The storage of the hard drive is 1GB to 1TB.

Memory is the random access memory. It has less capacity. The storage memory has is temporary. The speed of accessing in memory is slow. It is made of chips. It needs a power supply. It needs supply continuously. They have a storage location which is termed a memory location.

What is Hard Drive?

The hard drive is sometimes called a Hard Disk Drive. This is a non-volatile device. It is situated in the internal of the computer. It is kept attached to the disk controller. It is situated on the computer’s motherboard. It is sealed in the air-sealed casing. It lets the computer install any programs.

It is made of platters that are attached using magnetic heads. It uses a random-access manner to access the data. It is a rectangular box which is small. It was first made by IBM in 1956. It was very popular during 1960 as it was dominantly used for secondary storage devices.

The hard drive was manufactured by many companies, which became very useful in the computer due to its storage capacity. This has decreased because of the launch of many more devices like mobiles and tablets.

They use solid-state drives, which makes the devices handier. The solid-state drives have a high speed in processing data.

Hard Drive is kept on the actuator, which connects the platter so that the platter is capable of reading and write data and can share it with the next platters. These were used in general-purpose computers, and then they went on to be using in personal computers in the 1960s.

What is Memory?

Memory is an electrical part of the computer. It needs a power supply to store the data. The power supply should be continuous. The data storage capability is temporary. It collects all the data and stores all at low speed. The size of the storage is not much larger and has only space till GBs.

Memory is smaller than a Hard Drive. This acts as a temporary medium to stores the data of the computer. Memory is portable. The price is very low for the memory. The retrieve speed is also very low in memory because it does all its work at a low speed.

The memory contains a register in them. These registers are storage locations in the memory. The storage location can also be termed as a memory location.

The higher number of bits the memory can store shows its high capacity. It has three types of memory which are known as primary memory, secondary memory, and cache memory.

Memory is used for the immediate purpose of storage. This is a very important component of computers. Memory is used in the computer so that it can function properly. Memory plays a big role in the system. Memory is closely situated with the microprocessor of the computer.


Main Differences Between Hard Drive and Memory

  1. Hard Drive is a collection of magnetic disks, which are also known as a hard disk, but Memory is random access memory.
  2. The capacity of Memory is smaller than Hard Drive.
  3. Hard Drive has permanent storage, but Memory has temporary storage.
  4. The speed of access is fast in-memory than on the hard drive.
  5. Hard Drive is formed by platters and disks, but Memory is formed by chips.
  6. Hard Drive does not need a power supply, but Memory needs a power supply.
