When businesses retire IT equipment, securely disposing of sensitive data is critical. But unlike traditional hard disk drives (HDDs), solid state drives (SSDs) store data in a way that makes it far harder to fully erase.
Even when files are deleted or drives are reformatted, residual data can often be recovered — creating serious risks for organisations handling personal, financial or regulated information. This is why specialist physical shredding is the only truly reliable way to destroy SSD data permanently.
Why SSDs Are So Hard to Wipe
SSDs use flash memory chips instead of spinning magnetic disks. To extend their lifespan, they use a process called wear-levelling, which spreads data across different areas of the drive rather than storing it in neat, predictable blocks.
This creates several challenges for data removal:
- Deleted files are often left intact until overwritten
- Wear-levelling can bypass overwritten blocks
- SSDs include hidden or reserved sectors that wiping tools cannot access
As a result, even after a drive has been wiped, fragments of sensitive data can still remain in hidden areas of the memory and be recovered with forensic tools.
Why Wiping and Drilling Aren’t Enough
With HDDs, overwriting the disk surface is usually enough to erase data. But with SSDs, even multiple passes of overwriting software cannot guarantee complete removal because some sectors are never touched.
Similarly, basic physical methods such as drilling holes or crushing drives often leave large sections of memory chips intact. These chips can be removed from the drive and read directly using specialist hardware.
In 2020, the ICO fined a London law firm £98,000 after unencrypted personal data was recovered from old drives they had tried to wipe. It highlighted that data must be made irretrievable — not just deleted.
What Proper SSD Shredding Involves
To securely dispose of SSDs, physical destruction must be carried out to strict standards that ensure every memory chip is destroyed beyond recovery.
Best-practice SSD shredding includes:
- Reducing drives to particles of 2mm or smaller
- Completely destroying all flash memory chips
- Maintaining a secure chain of custody from collection through to destruction
- Providing a Certificate of Destruction for your compliance records
- Meeting or exceeding standards such as NIST 800-88, ADISA, and ISO 27001
This approach guarantees that no usable data remains and gives your business the documented proof needed to demonstrate compliance.
Common Mistakes to Avoid
Many organisations underestimate how different SSD disposal is from HDD disposal. Common errors include:
- Assuming a standard wipe will remove all data
- Using HDD-grade shredders that leave memory chips intact
- Relying on basic physical damage such as drilling
- Failing to verify a provider’s certifications, shred sizes or recycling practices
These mistakes can leave data recoverable and expose your business to GDPR breaches, regulatory fines, and reputational damage.
Choosing a Specialist SSD Disposal Partner
Secure SSD disposal is about more than convenience — it is about protecting your organisation’s data, reputation and compliance status.
When evaluating a provider, check that they:
- Are certified to standards such as ADISA and ISO 27001
- Use shredders that reduce SSDs to ≤2mm particles
- Maintain a complete chain of custody with asset logging and tracking
- Offer on-site shredding if you handle highly sensitive data
- Provide certified recycling to meet WEEE requirements
- Issue a Certificate of Destruction for every drive processed
