Drive Destruction or Data Erasure: Which is the Secure Data Wiping Method?
Summary: In this post, we’ve discussed two data disposal methods – data erasure and drive destruction. We’ve also mentioned the key differences between these two methods that can help you find out which approach is more effective and secure.
When you dispose of your end-of-life hard disk drive, solid-state drive, or any other storage media, you need to ensure that no sensitive and confidential data remain on these devices. If you’re not destroying that data properly, you could probably be putting the data at risk of being compromised.
To securely destroy data, you can either choose the drive destruction service or the drive erasure software. In this post, we’ll be discussing these methods in detail to help you find out which method is best for your data wiping needs.
What is Data Erasure?
Data erasure is a software-based method of overwriting data on storage media, such as HDD, SSD, memory cards, etc., with zeros and ones. The purpose of data erasure is to completely wipe the data stored on the storage media to make it unrecoverable. After data erasure, all the data is overwritten and the drive can be reused.
The data overwriting process for performing data erasure is based on the number of passes and patterns used. For instance, the DoD 5220.22-M standard uses three passes for data erasure with complete verification. Likewise, you can overwrite data with the desired number of passes according to your prerequisites.
What is Drive Destruction?
Drive destruction is a process to destroy the magnetic drives, hard drives, and other storage media physically, with the purpose to destroy data stored on them. It is also one of the data eraser methods to destroy end-of-life drives. It is a technique to run the drive through a machine called a shredder, which cuts all the components of the drive into tiny fragments.
Differences Between Drive Erasure and Data Destruction
Let’s discuss the differences between data erasure and drive destruction.
|Parameters||Data Erasure||Drive Destruction|
|Ease-of-Use||This is a software-based method that is performed easily and no technical expertise is required.||It requires expertise to run a shredder, e.g., loading a drive, shredding, etc.|
|Compatibility with Storage Media||It supports all media storage devices, like hard drives, SSDs, flash memory cards, etc.||Shredding also supports all types of media.|
|Drive’s Market Value After Data/Drive Destruction||The media can be reused after the process of data erasure.||The drives are completely destroyed.|
|Process Execution Speed||It is a DIY task performed using software, which takes only a few minutes.||The process includes running a specific machine, such as a shredder that takes longer to execute.|
|Eco-Friendliness||This method is environmentally friendly and helps companies fulfill their no e-waste commitments.||The machine breaks the drive into tiny fragments, thus generating e-waste.|
|Scalability||The data eraser software can erase data from multiple drives simultaneously.||A single drive is shredded at one time.|
|Price Component||It is a cost-effective software-based method with pay-per-use value licensing.||Higher operating costs are involved for media destruction in various facilities. Plus, the shredder will lose its performance value with time.|
|Data Erasure Certificate||It generates tamper-proof erasure reports and certificates to meet security and regulatory compliance requirements.||The company provides a drive destruction certificate, which acts as proof of destroying a drive. It also helps meet security and regulatory compliance requirements.|
Which is More Effective – Data Erasure or Drive Destruction?
Both methods – data erasure and drive destruction – are useful for destroying data. However, after looking at the points mentioned above, it can be said that data erasure is an easier and more reliable method to destroy the data. You only need software to perform the data erasure process, which you can do yourself at your own place, thus ensuring the security of data. Also, after data erasure, you can reuse the drive, thus preventing the generation of e-waste. On the other hand, for drive destruction, you need to submit the drive with a service provider which may involve the risk of a data breach.
Before disposing of your storage device, you need to make sure that your sensitive or personal data is completely destroyed from the device. You can choose drive destruction or data erasure method for data destruction, depending on your needs. However, the software-based data erasure process is easy to perform, requires fewer efforts, and is more secure as compared to drive destruction.
