Arrange the following types of memory in increasing order based on data transfer rate.

a. HDD

b. SSD

c. RAM

d. Cache memory

e. Registers

The correct answer is Option 2.

Key Points

• The data transfer rate refers to the speed at which data can be read from or written to a memory device.
• Memory devices arranged in increasing order of data transfer rate are HDD (Hard Disk Drive), SSD (Solid State Drive), RAM (Random Access Memory), Cache Memory, and Registers.
• HDD: Slowest among the given options due to mechanical parts and magnetic storage.
• SSD: Faster than HDD due to the absence of moving parts and reliance on flash storage technology.
• RAM, Cache Memory, and Registers: Progressively faster due to their proximity to the CPU and design for high-speed data transfer.

Additional Information

• HDD (Hard Disk Drive):
  • Uses spinning magnetic disks to read/write data.
  • Data transfer rates typically range between 80-160 MB/s.
• SSD (Solid State Drive):
  • Utilizes flash memory for data storage, enabling faster access speeds.
  • Data transfer rates range from 200 MB/s to 3,500 MB/s or more, depending on the interface (SATA, NVMe).
• RAM (Random Access Memory):
  • Volatile memory directly accessible by the CPU.
  • Data transfer rates typically range between 10-25 GB/s for DDR4 RAM.
• Cache Memory:
  • A small-sized, high-speed memory located inside or near the CPU.
  • Used to store frequently accessed data for quick retrieval.
• Registers:
  • Smallest and fastest memory directly within the CPU.
  • Handles data at CPU speed, typically in the range of several GB/s.
