What is SSD Hard Drive Definition? 11 facts you need to know about SSD.

What is SSD Hard Drive Definition?

What is SSD Hard Drive Definition? is a common question that comes to everyone’s mind when someone advises them to shift or buy an SSD hard drive or a laptop/computer fitted with SSD hard drive.

SSD Hard Drive is a mass storage device used in computers, just like a mechanical hard disk drive (HDD). They don’t have any magnetic, movable or spinning parts like HDD, this distinguishes them from traditional electro-mechanical drives such as a hard-disk drive or floppy disk and this is why they are called Solid State Drive.

You may take these storage drives as large USB drives, they use the same technology to run and store data, and that is non-volatile flash memory.

It uses flash memory to store data even when device power is turned off. SSDs are designed to read or write data in the same way as conventional hard-disk drives. SSD technology primarily uses similar input/output electronic interfaces compatible with traditional Hardware disk drives, which permits simple replacements in performant applications.

New i/o interfaces like SATA Express, m.2, and u.2 SSD drives have been created to manage specific requirements of the SSD technology, as SSDs are much faster than they could run using the traditional interface.

Because there isn’t any moving or small objects in these storage devices, they are much safer, calmer, durable, and quieter even in case of falling or any physical incident.

Because of non-movement and faster data sorting, these drives do less electric energy consumption.

In 1991 SanDisk corporation shipped the first SSD a 20 MB solid-state drive, which was sold to OEM for around $1,000. IBM used it on a ThinkPad laptop on September 8, 2008.

Intel began shipping of its first mainstream solid-state drives the X 18 M, and X 25 M with 80 GB and 160GB storage capacities in 2017. Intel launched the 900 P series of chain SSDs based on 3d xpoint technology as opposed to NAND flash memory.

11 New Thoughts About What Is SSD Hard Drive Definition That Will Turn Your World Upside Down.

  • SSDs are smaller, lighter, and quieter than Hard Disk Drive (HDD) and store data using flash memory. Solid-state drive stores data in semiconductors.
  • Solid-state Hard Disk Drives have lesser chances of data loss due to mechanical breakdown because they don’t store data magnetically.
  • Even at the time of power loss, it doesn’t require data preserving, because Solid State Drive doesn’t need the power to save Data. It may also use battery power to maintain data when its standard power is not available.
  • SSD’s are mainly equipped with electronic interfaces like IDE, SAS, and SATA. These were also equally suitable for traditional or say mechanical hard disk drives (HDDs), this makes it as easily replaceable from HDD.
  • On the contrary, new versions of Solid-state drives like SATA Express and M.2 are designed to fulfill requirements of Solid State Drive technology.
  • Even worst of the Solid-state drive is considered to be at least three times faster of HDDs. Nvme Solid State Hard Disk Drives are ten times faster than SATA SSDs. In this manner, they (Nvme SSDs) are at least 30 times faster than mechanical hard drives.
  • Quality, speed, and other properties of a Solid State drive depend on the number of bits Data stored in each cell. Each cell may contain 1 to 4 bits of data, while a lesser amount of bits means most reliable, durable, and faster data, but also the most expensive drive.
  • You may also get the point of view with an example that “Single Bit Cells (SLC)” being fastest and more reliable than 2 or 3 cells (MLC and TLC). Vice-versa, 4-bit cells (QLC) being the slowest of them all and also the cheapest of the four.
  • QLC (Quad level cells) are used in most consumer devices due to their specific property of cost-effectiveness. SSD hard drives using Nand flash generally lose their charge if left without power for a long time duration.
  • They start losing Data generally after one year or so in standard conditions. While storing at a lower temperature can increase their life a bit longer from 1 to 2 years.
  • Therefore, SSDs are not suitable for keeping and storing data for a more extended period if the devices aren’t in use regularly or say inactive.

What are Types of SSD Hard Drive

Although Solid State Hard Drive itself came with an enormous change in data storage speed. There have been many other inventions and alterations in the making of SSDs, which made them even faster, which we will talk about in the upcoming content.

What is SATA SSD Drive?

So, this was the best replacement of the mechanical hard disk Drives, without making any other change in PC or laptop you can get a faster storage drive. We can also call it a quick way out, and this is why Solid State drives became so popular.

Anybody could upgrade himself, or even production companies need to buy or develop a Solid State Drive, and bingo a new technology system was ready without any hassle.

Then came the different versions of SATA SSDs like SATA-2, SATA-3, and SATA Express. An average SATA Solid State Drive is five times faster than a standard HDD.

mSATA SSD Hard Drive

After the success story of SATA SSD drives, now a new debate started that “Why should we keep Solid State drives so big?” and hence, mSATA was introduced to save space.

Now, with the help of mSATA (mini-SATA), one could make lighter and sleek devices. These mSATA drives don’t have the outer shell as it was used in previous versions of SATA SSDs and run on the same technology as SATA-3.
But the problem of limited storage remained the same, and the Data read/write speed was also was precisely the same as SATA-3 SSDs, i.e., 550mb/s with the data transfer speed of 6GBps.

M.2 PCIe (NVMe) SSD Hard Drive

m.2 PCIe (Peripheral Component Interconnect Express) SSD hard drives are invented and introduced in the market. As these drives now have better connectivity directly to the CPU.

The original name of the M.2 form factor is Next Generation Form Factor (NGFF), this is internally mounted expansion cards for computers and associated connectors.

These m.2 PCIe Solid State drives are connected with NVMe (Non-Volatile Memory Express) protocol for accessing high-speed storage media.

Now, gone are the days of connectors and wires used to attach Solid State drives to power and CPU, so lesser connectors means lesser faults and an enhanced data read and write speed of 3.5GB/s and a potential data transfer speed of up to 32GB/s. These Solid State drives are responsible for making lighter, thinner, and Best SSD Laptops.

This speed of 3.5GB/s is seven times faster than SATA-3 SSDs and 35 times faster than the mechanical hard drives (HDDs). These m.2 Solid State Hard drives use up to 8 lanes for transferring data.

But still, each one dealing or using SSDs should know that even these advanced forms of m.2 SSDs are having a max capacity of 2tb Data storage, which can prove to be small for some users.

U.2 SSD Hard Drive

The latest form of Solid State drives for high data usage users is u.2 SSD hard drives. These drives have a different sort of double-decker port for higher durability.


Formerly U.2 Solid State drives were known as SFF-8639, but for making it easier to remember for you (General public), it was renamed as U.2, the successor of m.2.

The ports on these drives consume lesser space, and that’s why it is now easier to put more than one port for extra drive connectivity.

U.2 is the ultra high performing Solid State drive, not restrained with the small circuit board. Larger space for extra memory chips, which led to higher storage capacity.

Back with the outer shells, these U.2 Solid State Hard drives are also equipped with heat busters for controlling the temperature while running at incredible speed. But even though they use only four lanes for transferring data (whereas m.2 drives use eight lanes).

So, if you don’t need a Solid State Drive, which is beyond 2tb storage than m.2 PCIe SS drives are the best performing storage devices. One may go for u.2 Solid State drives if their need for data storage is beyond 2tb.

What is our Opinion for choosing SSD Hard Drives?

So, if you don’t need an SSD hard drive, which is beyond 2tb storage than m.2 PCIe Solid State drives are the best performing storage devices.

One may go for a hybrid drive (SSD + HDD) laptop if their need for data storage is beyond 2tb.

HDDs are impressive and price effective for high storage, whereas Solid State Drives are amazing for start-up and running of the operating system, programs, and applications.

And if you don’t want to comprise with quality at any cost, then you may go for u.2 Solid-state drives, which are the drives of tomorrow.
