A computer hard disk drive (HDDs) that is a non-volatile data storage device. It refers to Non-volatile storage devices that maintain stored data when turned off. All types of computers need a storage device, and HDDs are just one example of a type of storage device. Computer HDD is also connected to a power supply unit and can keep stored data while powered down.

1. History of hard disk drives
Hard disk was invented in 1953 by engineers at IBM who wanted to find a way to provide random access to high capacities of data at a low cost. Developed disk drives were the size of refrigerators, could store 3.75 MB of data and began shipping in 1956. So, Memorex, Seagate Technology and Western Digital were other early vendors of hard disk drive technology.
Hard disk drive form-factors continue to decrease in size as technology evolves. By the mid-1980s, 3.5-inch and 2.5-inch form factors were introduced and became a standard in personal computers.
2. Why do computers need hard disks?
Computer needs Storage devices like hard disks are needed to install operating systems, programs and additional storage devices, and to save documents. In this case without devices like HDDs that can retain data after they have been turned off, computer users would not be able to store programs or save files or documents to their computers. That’s why every computer needs at least one storage device to permanently hold data as long as it is needed.
3. How do hard disk drives work?
All basic hard drives consist of several disk platters a circular disk made of either aluminum, glass or ceramic that are positioned around a spindle inside a sealed chamber. So, that the platter spins with a motor that is connected to the spindle. In this chamber also includes the read/write heads that magnetically record information to and from tracks on the platters using a magnetic head. So, that can we say disks also have a thin magnetic coating on them.
4. Hard disk drive storage capacity
Part of the most common storage drive capacities include the following:
- Included 16 GB, 32 GB and 64 GB. This Selection is among the lowest for HDD storage space and is typically found in older and smaller devices.
- Includes, 120 GB and 256 GB. This Selection is generally considered an entry point for HDD devices such as laptops or computers.
- Includes, 500 GB, 1 TB and 2 TB. Surrounding 500 GB and above of HDD storage is typically considered decent for an average user. There are Photos, videos and other files with this much space. So that Individuals with games that take up a lot of space should find 1 TB to 2 TB of HDD space suitable.
- At this stage, Storage the highest capacity HDD is 20 TB. Notwithstanding an HDD actually has less space than advertised, as the operating system, file system structures and some data redundancy procedures use a portion of that space.
5. Hard drive components and form factors
The components include in the HDD like Spindle, Disk platter, actuator arm and read/write head.
The form of factor HDD refers to the Physical size or geometry of the data storage device.
HDD form factors succeed a set of industry standards that govern their length, width and height, as well as the position and orientation of the host interface connector.
That is also important to note that while nominal sizes are in inches, actual dimensions are specified in millimeters.
6. What are external HDDs?
Mostly HDDs are found internally in a computer and work as stated above. Whenever, individuals can also purchase external hard drives. So that External hard drives can be used to expand the storage capacity of a computer or to act as a portable device to back up data. For that case External drives connect to a computer or device through interfaces like USB 2.0, USB-C or with External SATA (eSATA). Then External hard drives may also have slower data transfer rates compared to internal HDDs.
7. HDDs vs. SSDs
All type of storage has benefits and drawbacks. In comparison of hard disk drive and solid state drive is needed to be determined it is the best for workload:
- Capacity – In a key difference in storage space is that SSDs use flash memory instead of magnetic platters. So, the latest SSDs have commonly used capacities like 128GB, 256GB, 512GB, 1TB and 2TB.
- Performance – The speed at that an SSD accesses data is much higher than an HDD speed. These faster speeds allow for spontaneously startup and less latency when we logging in to a device or load times on apps
- Lifespan/durability – HDD are better long-term storage device that can be used too long.
8. 5 Benefits Of Using HDD For Data Storage
- HDDs one of the most affordable compared to other data storage devices. Whenever it comes to affordability, HDDs are still considered the most pocket friendly. Hard drives such as SAS-3Gbps HDDs are much cheaper than SSDs of similar capacity.
- HDDs are easily available in the market the fact that HDD computers have been in manufacture since the early part of production history suggests that they come to market in large quantities. Whether it’s an external or internal hard drive you’re looking for, chances are you can certainly find one in a tech shop.
- HDD has large storage base capacity HDDs have large storage base capacity options found in the market with a standard size of 500 GB which is more than half of the starting capacity of SSDs
- HDDs have a non-volatile memory losing data during power outages can be a nightmare. And this is definitely true with volatile memory devices. In this circumstance, it is common to experience problems such as opening a particular application or file or loading the operating system.
- HDDs have a longer lifespanhaving a higher read-write cycle is a clear benefits of HDDs as data is directly written on the platter disks. So, these platter disks have high durability and rarely deteriorate.
9. Conclusion
Every modern hard drive is perfectly capable of handling your Daily data, and mostly drives perform well enough to support everything you want to do today.so, if you are of an impatient nature and have a loose budget, In that if your requirements are simply very high, you should always go for a 10,000 RPM Western Digital Raptor drive. Each and Everyone else can buy into a decent 7,200 RPM model at a variety of capacity points for a reasonable cost. Although still being able to squeeze some more performance out of hard drive technology that has only changed in the details after 50 years. So the (IBM’s 305 RAMAC was introduced in 1956.).

14. If it finally fails, the whole computer stops working at that very moment or that point in time.
3. What is the Difference between HDD and SSD?
1. The full form of HDD Stands for Hard disk drive. And it is SSD stands for Solid state drive.
2. HDD consist of moving mechanical parts, such as the arm.
3. SSD does not consist of the mechanical parts only this is electronically parts like ICs.
4. HDD it is heavier in load and SSD is lighter in load
5. HDD is cheaper per unit storage but SSD is high price per unit storage.
6. If we see then HDD is older and more traditional, then SSD is newer to use.
4. How much faster is SSD than HDD?
Solid state drives outperform hard disk drives in speed, while matching them in everything else except price. In this respect SSD is better than HDD. But, although SSDs are coming down in price, they are still more expensive than traditional HDDs. If an HDD can even meet your needs, you may not want to pay for an SSD. Loading large amounts of data is only a small part of what you do on a computer Daily basis, It’s depends on your habits or profession. If SSDs cost about twice as much per gigabyte and only provide a significantly different experience in a few limited situations (situations you might never even encounter), do you really need it? If you don’t deal with large files regularly, SSDs can be an unnecessary luxury.
5. There are three types of hard disk?
So, there are three types of hard drives: SATA, SSD and NVMe. In accordance with. You will learn about each type and their strengths and weaknesses. Whether you are considering buying or building a new PC or upgrading your current one, this will help you choose one over the others.
6. How can I change HDDD to SSD?
1. Mostly new laptops and desktop computers come with solid-state drives (SSDs) installed instead of the traditional hard disk drives (HDD) we have all been used to over the past 30-plus years. If you have own a computer with an HDD, you might be finding that it runs a little slower and maybe you want to boost performance by installing an SSD.
2. A computer is more than two years old, replacing the hard drive with an SSD is one of the most cost-effective changes you can make. That’s why, there are some practical challenges you will need to consider before committing, so starts take a closer look at SSD drives next.
