SSD is an abbreviation and stands for solid state drive or solid state disk.
SSD is a drive that allows you to store and access data, similar to computer RAM. Unlike a hard disk, an SSD has no moving parts. This makes access to stored information faster and operation quieter.
Now that prices are moderate, SSDs are suitable as spare parts for desktop and laptop computers.
A History of Hard Drives and SSDs
Hard disk technology is relatively old (in terms of computer history). There are known images of the infamous 1956 IBM 350 RAMAC hard disk, which used 50 24-inch wide disks to hold a whopping 3.75 MB of disk space. This is of course the size of an average 128Kbps MP3 file today. With the RAMAC 350, IBM has limited itself only to government and industrial applications.
Isn’t progress wonderful? The 5.25 inch PC hard disk was developed in the early 1980s. The 3.5-inch drives and 2.5-inch notebook drives came shortly afterwards. The internal cable interface has changed over the years from serial to IDE (now often called parallel ATA or PATA) to SCSI to Serial ATA (SATA). But function is the same: You connect the hard disk with the PC motherboard. Today’s 2.5″ and 3.5″ drives mainly use SATA interfaces (at least on most PCs and Macs), although some high-speed SSDs use the faster PCI interface. Capacities have grown from several megabytes to several terabytes.
SSDs vs. HDD: What’s the difference?
Until recently, PC buyers had very little choice about what kind of memory was available in a laptop or desktop. If they bought a high-end laptop, they probably had a solid-state drive (SSD) as their primary drive. Any other desktop or Laptop came with a “normal” HDD hard drive therefore. In the meantime, they can configure most PC systems with an SSD. Even a combination of HDD and SSD is possible.
But which one would you choose?
The traditional HDD hard disk is a non-volatile data storage device. This means that when you turn off the system, information is not lost, as is the case with data stored in RAM. A hard disk is essentially a metal plate with a magnetic coating that stores your data. Whether music, games or movies. A read/write head in the hard disk accesses the data as the disks rotate.
The functions of a solid-state disk are similar to those of a hard disk. But the data is stored on interconnected flash memory chips instead of a memory. The chips can be installed either on the system’s motherboard (as on small laptops) or on a PCI Express.
The SSD has a much shorter history. The current flash memory is the logical extension of the same idea. The first primary drives we know as SSDs began during the rise from netbooks in the late 2000s. In 2007, the OLPC XO-1 used a 1GB SSD and the Asus Eee PC 700 series used a 2GB SSD as primary storage. The SSD chips on low-end PC units and the XO-1 were permanently soldered to the motherboard. As netbooks and other ultraportable laptop PCs became better and more powerful, SSD capacities continued to increase. Nowadays, you can easily replace a 2.5-inch hard drive with an SSD.
Advantages and disadvantages
Both SSDs and HDD hard drives do the same job: You boot your system and save your applications and personal files. But you do differ in some ways. wisely.
How do they differ?
Price: SSDs are more expensive than HDD hard drives in terms of Euro per Gigabyte. A 1TB internal 2.5-inch hard drive costs between 30EUR and 50EUR. In contrast, an SDD with the same capacity costs on average 300EUR. This corresponds to 3 cents per gigabyte for the hard disk and 30 cents per gigabyte for the SSD. Since hard disks use older, but more established technology, they will remain price-stable in the near future.
Speed: Here the SSDs shine. An SSD-equipped PC starts up in less than a minute, often in seconds. A hard disk requires time to accelerate the operational data. A PC or Mac with SSD boots faster, starts apps faster, and transfers files faster. Whether you use your computer for fun, school or work, the extra speed can be worth it.
Fragmentation: Because of their rotating recording surfaces, hard disks work best with larger files stored in contiguous blocks. In this way, the drive head can start and stop in a continuous movement. When hard disks start to fill up, large files can be scattered across the HDD disk, causing the speed to suffer from what is called fragmentation. Due to the absence of a physical read head, SSDs can store data anywhere without time loss. So SSDs are faster.
Durability: An SSD has no moving parts, so it’s more likely that your data won’t be lost due to a physical defect. When the computer system is turned off, most hard drives “park” their read/write heads. Nevertheless, the reading heads have a game of a few nanomillimeters. These nanomillimeters are sufficient to produce an HDD. demolish
Noise:Even the quietest hard disk will cause a bit of noise when in use, when the drive is rotating or the reading arm is moving back and forth. SSDs cause practically no noise because they are not mechanical.
Conclusion: HDD hard drives are clearly ahead in terms of price, capacity and availability. SSDs are a lot more expensive, but work the fastest and most reliable. If price and capacity do not matter, SSDs would be the best choice.

The storage medium of tomorrow
It is unclear whether SSDs will completely replace traditional HDD hard drives, especially in times of cloud storage. While the price of SSDs is becoming more affordable, they are still too expensive to completely replace the terabytes of data some users have in their PCs and Macs. Cloud storage is not free either.
If we catch up, the SSD gets 9 and HDD gets 3. does that mean that an SSD is three times better than a hard drive? Not at all. As we have already mentioned, everything depends on individual needs. The comparison here is just to put the pros and cons for both options. To help you even more, here are some rules to follow when you decide which drive is best for you:
An HDD hard drive might be the right choice if:
– you need a lot of storage capacity (up to 10TB)
– Don’t want to spend a lot of money
– you don’t care how fast a computer boots up or opens programs
An SSD might be the right choice if:
– You are willing to pay for faster performance
– You need unlimited storage capacity
– you want to have a fast boot process
