Hello, readers welcome to new post. Here we will discuss Difference Between HDD and SSD. These two storage are called nonvolatile storage devices that used in personal computers and other devices. The common difference between this two storage is that the technology used for storing the data both use different techniques for storing od data.
In this post, we will discuss different paramerts of these two storage devices and different related functions. So let get started.
Difference Between HDD and SSD
What is HDD
- The HDD stands for hard disk drive is data storage device of electro-mechanical natures that uses magnetic storage for storing and retrieving data.
- With magnetic storage uses rotating platters having a coating of magnetic material.
- Platters are grouped with the magnetic head normally configured at a moveable actuator arm that helps to read and write data from the platter surface.
- Data is get in a random way which means single block of data can read and get in any sequence.
- HDD is a non-volatile memory unit that stores data if power is not connected. The shape of the HDD is a rectangle.
- It was invented by IBM in 1956 and was commonly used for general-purpose computers at the start of 1960
- Now it is very commonly employed in servers and PCs.
- Including Toshiba Seagate, almost 224 companies are making this storage device.
What is SSD
- SSD stands for solid-state storage devices used for ICs to store data through the use of flash memory and work as secondary storage.
- It also named as semiconductor storage devices, solid-state disks, and solid-state devices.
- SSD does not have moving parts like the HDD and has very fast access time, It stores data in microchips that make it operate faster.
- SSD has a smaller size than HDD and can be connected to the motherboard. Simply, it is an advanced form of USB
- It relies on the flash memory having NOR and NAND as two flashes. In mostly SSD NAND flash memory is used since it is high speed and has a smaller size than NOR,
- It is also a nonvolatile memory unit that stores data when power is off.
- There is processor is used in the storage to read and write data. The controller of SSD defines the reading and writing speed of SSD.
Why SSD Is Better Than HDD
- Some points make SSD better than HDD.
- Speed: The speed of SSD is higher than the HDD and does not have a moveable portion, so it can read data ten times faster than HDD and twenty times the writing speed higher than HDD.
- Efficiency: It uses less power than the HDD, so energy efficient this storage
- Less Overheat: SSD is less heat-resistant than HDD. So its performance is better than HDD. .
- Less weight: The weight of the SSD is less than the HDD.
Hard Disk Drive (HDD) vs. Solid State Drive (SSD)
HDD
- HDD in full form is a hard disk driver.
- HDD comes with some mechanical components, such as an arm.
- It has a longer read-writing time.
- It has high latency.
- It supported fewer input-output operations per second.
- It is heavy and larger than the SSD.
- It transfers data in sequence form.
- Low cost per unit area
- It is an older module and produces noise as a result of mechanical movements.
- For longer-term storage, it is used.
- It has a slower data access speed than SSD.
SSD
- The full form of SSD is solid-state driver.
- SSD does not have a moveable component and comes with ICs.
- It has a short read-writing time.
- It comes with low latency.
- It has features for supporting more I/O operations per second.
- It is low-weight and compact in size.
- It has random data access.
- It is reliable and has a low cost for single-unit storage.
- It is a noiseless operation.
Which lasts longer, SSD or HDD?
- For some components, measures are normally thousands or also 10 of thousands of hours for damage. Such as HDD comes with a mean time for failures of 300000 hours and SSD can be 1.5 million hours.
What are the disadvantages of HDD?
- The disadvantages of HDD are that mechanical components are used for reading and writing data, and physically finding and retrieving data takes more time than electronically finding and retrieving data.
Can I replace HDD with SSD?
- The replacement of hard drives with SSDs is a common feature that can increase the performance of older computers. Without moving components, SSD works noiselessly and effectively.
Does SSD make PCs faster?
- SSD has a short boot time of computers, high-speed data transfer, and high bandwidth. High speeds define that SSD has features for handling data with high speed.
