All about Hard Drive Destruction Vol.2
What is hard drive destruction? It is likely that your computer’s hard drive contains significant amounts of personal or confidential business information. As computers continue to play a large role in most Canadian’s lives, keeping your personal information stored on your hard drive safe and private is important. However, most people replace their computers every 4-5 years.
When it’s time to replace your computer, hard drive destruction is one of the best ways to ensure your information is appropriately removed. In this guide, we will answer common questions regarding hard drive destruction so you can make an informed choice when it comes to your own computer.
It is likely you have heard the term “hard drive,” but do you know exactly what it is or what it does on your computer? The hard disk drive, often shortened to just “hard drive” or “HD,” is usually the largest data storage device component of your computer. The hard drive is a hardware – meaning it has its physical component you can actually see, touch, and remove from your computer.
If you are building a computer or want to replace your hard drive, you can purchase hard drives separately from manufacturers such as Seagate, Toshiba, and more. However, most individuals and business owners will never need to purchase an additional hard drive – it is likely you will always use the hard drive that came with your computer.
Hard drives store almost everything on your computer, including your operating system, most software, and most of your files. Even when your computer is powered off, your hard drive holds on to all of the information you have stored on it. Some hard drives can hold up to 500 GB of data or more. That’s a lot of information!
Why Destroy A Hard Drive?
Unfortunately, simply deleting all of your data off a hard drive and throwing it out is not a safe solution. Data can be still be recovered even if you have deleted it. That’s why it is important to properly destroy the actual physical hard drive. Your hard drive may be storing significant amounts of information you do not want others to get a hold of. Information such as:
- Your name, address, date of birth
- Bank numbers and information (if you’ve used online banking)
- Credit card information
- Business information or files you’ve saved on your computer
- Online shopping or social network information
- Personal photographs
- And much more
Though you may believe you have properly wiped your hard drive, there is software available that makes recovering data easy for cyber criminals and identity thieves. If you are throwing away your old computer, you should ensure the hard drive has been wiped and then destroyed.

Beyond that, though, there are probably at least a few things you didn’t know about this ubiquitous piece of computing equipment:
- The very first hard drive, the 350 Disk Storage Unit, didn’t just show up on store shelves out of nowhere but was part of a complete computer system by IBM, released in September 1956… yes, 1956!
- IBM started shipping this amazing new device to other companies in 1958 but they probably didn’t just stick it in the mail – the world’s first hard drive was about the size of an industrial refrigerator and weighed north of one ton.
- Shipping that thing was probably last on any buyer’s mind, however, considering the fact that in 1961 this hard drive rented for over $1,000 USD per month. If that seemed outrageous, you could always purchase it for a little over $34,000 USD.
- An average hard drive available today, like the 8 TB Seagate model at Amazon that sells for a little over $200 USD, is over 300 million times cheaper than that first IBM drive was.
- If a customer in 1960 wanted that much storage, it would have cost her $77.2 Billion USD, a little more than the entire GDP of the United Kingdom that year!
- IBM’s expensive, monstrosity of a hard drive had a total capacity of just under 4 MB, about the size of a single, average-quality music track like you’d get from iTunes or Amazon.
- Today’s hard drives can store a bit more than that. As of late 2015, Samsung holds the record for the largest hard drive, the 16 TB PM1633a SSD, but 8 TB drives are much more common.
- So just 60 years after IBM’s 3.75 MB hard drive was the best of the best, you can get over 2 million times as much storage in an 8 TB drive and, as we just saw, at a tiny fraction of the cost.
- Bigger hard drives don’t just let us store more stuff than we used to be able to, they enable entirely new industries that simply couldn’t have existed without these major advances in storage technology.
- Inexpensive but large hard drives let companies like Backblaze provide a service where you back up your data to their servers instead of to your own backup discs. In late 2015, they were using 50,228 hard drives to do that.
- Think Netflix’s needs are big? Facebook was storing close to 300 PB of data on hard drives in mid-2014. No doubt that number is a lot bigger today.
- Not only has storage capacity increased, but size has also decreased at the same time… drastically so. A single MB today takes up 11 billion times less physical space than an MB did in the late ’50s.
- Looking at that another way: that 256 GB smartphone in your pocket is equivalent to 54 Olympic-sized swimming pools completely full of 1958-era hard drives.
- In many ways, that old IBM hard drive isn’t that different than modern hard drives: both have platters that spin and a head attached to an arm that reads and writes data.
- Those spinning platters are pretty fast, usually turning 5,400 or 7,200 times per minute, depending on the hard drive.
