SSD is faster at reading and writing data, whereas HDD has a slower reading and writing data speed.
SSD vs. HDD Here are the key Difference you should know.
Cant decide SSD or HDD Which is Better for You?
The difference between hard drives and solid-state drives is in the technology used to store and retrieve data.
HDD utilizes a magnetic disk as storage, whereas SSD utilizes memory.
HDDs are cheaper and you’ve got the option to get more storage space.
SSDs however are faster, lighter, more durable, and use less energy.
Your needs will dictate which storage drive will work best for you.

What is HDD ( Hard Disk Drive)?
HDD stands for hard disk drive.
The hard disk drive is invented byIBM[International Business Machines] in 1956.
When it launched it got very popular and it became the preferred storage drive in the 1960s.
Now, you will get HDD in a very small size with a large amount of storage space.
The hard drive is amechanical deviceandmoving partshas some friction loss because of that it produced noise when its running.
The read write speed of HDD is around 40-50mbps.
So, if you have more data backup then it takes more time to copy into the hard drive.
Each platter is organized into concentric circles, called tracks.
Tracks are divided into logical units called sectors.
Each track and sector number results in a unique address that can be used to organize and locate data.
Data is written to the nearest available area.
The higher the preset speed, the faster a hard drive will be able to read and write data.
What is SSD [Solid State Drive]?
SSD stands for solid-state drive, based on a microchip, this is a very fast and secure drive.
These storage devices were invented in the 1970s but these drives are comparatively expensive.
But when SSD size is an increase, the companies sell it as permanent storage drives.
Nowadays SSD competes for HDD on each and every function.
SSD usesflash memoryinstead of moving parts.
SSD hasnt any moving parts so there is no jot down of data loss problem or drive corrupt problem.
But SSD drives are more expensive with less storage space compared to HDD.
Solid-state drive (SSD)
An SSD is available in two different interfaces: SATA or PCIe.
PCIe has up to 4 times the theoretical bandwidth of SATA and is supported by the NVMe host protocol.
Architecture
HDDs:HDDs consists of a head and a revolving disk.
The data is stored in that Semiconductor Flash Chips instead a revolving disk.
read-and-write heads are positioned on top of the disks; all this is encased in a metal case.
SSD has no moving parts; it is essentially a memory chip.
It is interconnected, integrated circuits (ICs) with an interface connector.
There are three basic components controller, cache and capacitor.
But if we compare with the New latest SSDs the speed of HDDs is very low.
The Speed is almost 6 times faster than the older HDDs.
So that the scattered data can be arranged in the proper manner.
SSDs:There is no sequential writing of the Data so there is no need of DEFRAGMENTATION in SSDs.
Storage Capacity
HDDs:The Storage Capacity of the HDDs are basically the maximum.
The HDDs are available in the TBs, HBs, ZBs.
Data Loss
HDDs:In this, data loss is the major problem.
After multiple overwriting and as the HDD gets older the risk of the Disk getting Corrupted increases.
The normal estimated lifespan of the HDDs is basically around 5 Years.
SSDs will never get Corrupted due to multiple overwriting.
The lifespan of the SSDs are almost infinite.
SSDs:SSD drive performance is not impacted by fragmentation.
So defragmentation is not necessary.
SSD vs. HDD: Which is Better for You?
SSD has access speed of 35 to 100 microseconds, almost 100 times faster than a traditional mechanical HDD.
This means increased read/write rate, faster loading of applications and decreased booting time.
This could make a significant difference when using portable devices powered by a battery.
So the answer to that question is for you to decide.
You must achieve balance.
But then again, SSD is awesome!
