NVRAM and SSD are both storage devices, but they have different purposes. NVRAM is used to store data that needs to be accessed quickly, while SSDs are used for long-term storage.
In this article, we’ll compare NVRAM and SSD, including their benefits and drawbacks.
What is RAM?
Memory is a vital component of any computer, serving as a temporary data store for information that needs to be quickly accessed by the processor. There are two main types of memory in use today: dynamic RAM (DRAM) and static RAM (SRAM).
DRAM is the most common type of memory, used in everything from desktop computers to laptops and cellphones. SRAM is more expensive per byte, but is typically faster and requires less power than DRAM.
As a result, it is often used in embedded systems where space and power are at a premium. Regardless of the type of memory used, its performance is essential to the overall speed and efficiency of a computer.

What is NVRAM?
NVRAM, or non-volatile random access memory, is a type of RAM that retain its data after the power has been turned off. Unlike regular SRAM, NVRAM does not require a constant refreshing signal, making it ideal for situations where there is no active CPU.
Unlike regular DRAM or SRAM, NVRAM has backup flash memory, a small controller, and a battery or super-capacitor. This allows it to keep its data even when the power is off.
When power is restored, the controller moves the contents of the flash back into the SRAM or DRAM and the processor can resume operation where it left off.
This makes NVRAM especially useful for applications where data needs to be preserved even when there is no power.
There are several different types of NVRAM, each with its own advantages and disadvantages. FRAM, or ferroelectric RAM, is one of the most popular types of NVRAM. It is fast and reliable but can be expensive. MRAM, or magnetoresistive RAM, is another type of NVRAM that is slowly gaining popularity.
It is less expensive than FRAM and can retain its data for much longer periods of time, making it ideal for applications where data needs to be stored for extended periods.
What is SSD?
With the ever-growing popularity of laptops, tablets, and other mobile devices, solid-state drives (SSDs) are becoming increasingly common. SSDs are an alternative to traditional hard disk drives (HDDs) and offer several advantages over their spinning counterparts.
For starters, SSDs have no moving parts and are therefore much more resistant to physical shock. They also have very fast access times due to their lack of latency, which is the delay that occurs when a disk starts spinning up to reach its operating speed.
This can make a big difference in system response time, especially if the SSD is used as the main drive. In addition, SSDs tend to be more energy-efficient than HDDs and generate less heat, which makes them ideal for use in portable devices.
Finally, SSDs are generally quieter than HDDs since they don’t have any moving parts. All of these factors make SSDs an attractive option for anyone looking for a faster, more durable, and more efficient storage solution.
