Are you about to dispose of obsolete IT equipment and are you unsure between software wiping or physically destroying the SSDs (the internal storage media)? The short answer: both methods are 100% safe and AVG-proof, provided they are carried out by a certified ITAD partner such as W3E.
The choice depends on your priorities. Physical destruction gives you the absolute certainty that a data carrier is never again usable, especially because you can see for yourself that the SSD has been completely destroyed. Certified erasure (for example via Blancco software) makes the data permanently unreadable. The great advantage of this is that the hardware remains usable for a second life. From a sustainability and financial perspective, erasure is almost always the best choice, unless the disk is defective or your strict corporate policy requires otherwise.
In this article we will tell you more about both methods. data destruction, so that you can make an informed choice for your organization.
Why is it important to have SSDs certified for wiping?
SSDs store data in memory chips and use wear leveling: a smart technology that continuously moves data across the chips to distribute wear and tear. The result is that data also ends up in underlying or reserved memory cells where the operating system does not have direct access.
Are you emptying your SSD by moving files to the trash or choosing standard SSD formatting? Then only the visible index is deleted, but the actual data in those deeper memory cells remains intact. Business and personal data can therefore be easily recovered with recovery software. Only specialized software that reaches and overwrites all physical memory cells on the chips and guarantees physical data destruction ensure that the data is permanently gone.
Option 1: Certified software wipe
In software wiping, also known as data wiping, specialized software overwrites the entire storage capacity of the SSD using strict international standards. Software such as Blancco overwrites the memory chips down to the deepest level, including the reserve cells that are invisible to the user.
- How it works: We use Blancco software to systematically wipe the SSD. This software performs a hardware-based Secure Erase: an advanced command that electrically resets all the memory cells on the chips at once. After the process, the software performs an automatic verification to check that the data has actually been completely erased. We guarantee that we completely wipe the SSD drive.
- The big advantage: The hardware remains completely intact and the SSD performs like new after the Secure Erase. This allows the equipment to be reused without any problems. be safely reused or sold.
- Impact: This is the best choice for the circular economy. You reduce the e-waste mountain, reduce the carbon footprint of your IT department and maximize the potential residual value of the equipment.
Option 2: Physical data destruction
In the case of physical destruction, the SSD is crushed into small pieces by an industrial shredder. Because the chips on an SSD are very small, the shredder crushes the disk into small pieces of only a few millimeters; otherwise, an intact chip could theoretically still be read out.
- How it works: The disc is literally destroyed into unrecognizable, unusable fragments. For maximum transparency, this can often also be done at your location with our mobile shredder.
- The big advantage: You have visual confirmation that the device no longer exists. This psychologically removes all doubt and meets the strictest safety requirements of, for example, governments, the defense sector or financial institutions.
- Impact: The hardware is discarded for reuse. However, the remaining scraps (such as copper, gold and plastic) are melted down by specialized recyclers into new raw materials.
Destroy or destroy: which option do you choose?
To make the decision easier, we list the considerations:
- Choose software wipe if: the equipment is still working and you want to contribute to sustainability goals (ESG). Because of the residual value of the working equipment, this is often the most cost-effective choice.
- Choose physical destruction if the SSD is defective (and software wiping is therefore technically impossible), or if you are working with state secrets or extremely classified data where the internal protocol requires that storage media must not leave the premises in one piece.
The GDPR and the importance of the certificate
Whatever option you choose, the responsibility for data breaches remains legal, according to the GDPR, They are always with your organization. Therefore, implementation may be even more important than the method itself.
Never attempt to work with drills, hammers or free software yourself. A certified data destruction partner will always hand you over a certificate after the process. Certificate of destruction (Certificate of Erasure or Destruction) per serial number. This document is your legal proof of audits that the data has been destroyed in a conclusive, secure manner.
Which is the best choice?
From the perspective of data security, there is no winner in a certified process: both options are 100% secure. However, if we consider modern IT management and the shift towards a circular economy, software wiping is the clear leader. You optimally protect your data, potentially generate budget from the residual value, and give working technology a second life.
At W3E, we are happy to advise you on the right strategy for your IT hardware. Whether that means software wiping or physical shredding; we always ensure a hassle-free, sustainable and guaranteed safe process. Would you like your SSDs wiped or do you have any questions?
