In the modern era, hard drives are considered as one of the most popular storage devices. By definition, a hard drive or hard disk drive (HDD) is a fixed data storage device that utilizes the magnetic storage technology to store and retrieve the digital information using rotating disks. In the absence of a hard drive, you will not be able to install various applications on your device. In this post, we’ll shed some light on the interesting things you don’t know about hard drives. Read on to explore every nook and cranny of this ubiquitous piece of computing equipment.
Amazing Things to Know About Hard Drives
- The first hard drive ever: The 350 Disk Storage Unit was the very first HDD, released in September 1956 by IBM. It came with the storage capacity of 3.75MB.
- IBM began shipping this incredible hard disk to other companies in 1958. The world’s first hard drive was about the size of an industrial refrigerator and weighed north of one ton.
- When this enormous drive became commercialized, it cost approx $35,000. If we talk about the price per storage unit, it was accordingly around $8500 per MB, which is 170Mn times pricier as relative to the average 5 cents per GB today.
- In this techno-digital era, an average hard drive like 8TB Seagate model sells for a little over $200 USD that is more than 300Mn times cheaper than the first IBM drive. In other words, the new 8TB hard drive would have cost $77Bn in 1960.
- Another thing you’ll surely want to know about hard drives is the storage capacity of IBM’s drive. Well, the world’s first HDD had a total capacity of 4MB. Generally speaking, it’s about the size of a single, average-quality music track.
- Modern hard drives are able to store a bit more than that. Starting from late 2015, Samsung holds the record for the largest hard drive namely the 16TB PM1633a SSD.
- Want to know about hard drives regarding the progress? Well, if you’re a tech buff, you may have heard about Moore’s law – every two years, storage space and computing power of systems nearly doubles. Sadly, Moore’s law has halted with HDDs since the technology is achieving its physical limits. Though there’re some ways to fix it, the rapid progress part has moved to SSDs.
- Hard disk platters are made from expensive materials such as Platinum for its thermal properties and ruthenium for achieving the magnetic properties.
- One thing we bet you probably don’t know about hard drives is that they are not airtight. However, they boast filters to avert dust in the enclosure that could terribly affect your important data.
- Conventional hard disk drives feature a capacity limit as air resistance and power constraints limit the platters’ amount one disk can embrace. Diverse aerodynamic processes make it really complex to push too many platters into one HDD, while other such rules together with power requirements make it hard for the platters to spin above 15K RPM (Revolutions per Minute).
- Hard drives are restricted by the space that one bit employs on the disk platters as there’s a least constraint for the read/write head to be able to read the information.
- On the compact storage front, when compared to modern storage devices, the 350 Disk Storage Unit occupied around 10Bn times more space per MB than an average HDD today.
- Yet another thing you don’t know about hard drives is that their size has drastically decreased relative to the late ones. A single MB today eats 11Bn times less physical space than an MB did in the late 50’s.
- You’ll be amazed to know that 256GB smartphone in your pocket is equivalent to 54 Olympic-sized swimming pools completely beset with 1958-era hard drives.
- However, modern HDDs are similar to old IBM drive in many ways like both have a head attached to an arm that reads and writes data and both boast platters.
- Do you know about fast spinning platters are? Well, you don’t! They usually turn 5400 or 7200 times per minute counting on the HD.
- The next thing you need to know about hard drives is that all of the moving parts produce heat. And you may have heard a soft noise from your computer. This noise is probably created by the fans during circulating air.
- With the rise of Solid State Drive (SSD) in the computing industry, the concept of typical hard drives will perhaps be the next to end.
- Another useful thing to know about hard drives is that your system makes use of them as a sort of ‘scratch pad’. So, you always need to have approx 10% of your hard disk space free for your computer’s own internal use.
- Data is stored in an HDD in the form of 0 or 1.
- Data bits are organized in concentric or circular paths dubbed tracks. Each track is divided into smaller parts known as sectors. When your system needs to store new information, your HDD takes a look at the File Allocation Table (FAT) to find free sectors. Afterward, it gives instructions to the read-write head to move across the platter to exactly the right location and store data there. In order to read data, the same process runs but in the reverse order. That’s how your data stores on a hard disk drive.
So, these were some little-known facts that you probably don’t know about hard drives. We bet you have learned a lot more about this omnipresent computing equipment, haven’t you?
