SSDs, or solid state drives, utilize flash memory instead of traditional hard disk platters found in hard disk drives (HDDs). This allows SSDs to access data much faster since there are no moving parts (Randy Lundin, “Advantages of Solid State Drives”). However, this also makes SSDs more susceptible to damage from external magnetic fields. The NAND flash memory in SSDs uses electric charges to store data bits, and strong magnets can alter or erase these charges (R. Micheloni et. al, “Communicating With Your SSD: Technology Overview”). While magnets have many constructive uses, placing them too close to an SSD can irreparably corrupt or erase data.
Warning Against Intentional Damage
Deliberately damaging computer hardware like SSDs, even your own, can have serious legal consequences. According to the Computer Fraud and Abuse Act (18 U.S. Code § 1030), it is a federal crime to knowingly cause unauthorized damage to a protected computer. SSDs in computers, even personal ones, are considered protected computers under this law. Conviction can lead to fines and imprisonment.
Intentionally destroying an SSD with magnets demonstrates intent to damage computer equipment. Even if it’s your own device, this act could potentially violate laws against destruction of property and equipment, resulting in prosecution (Destruction of Computers Equipment). There are ethical concerns as well about wasting resources and polluting the environment with e-waste.
Before attempting to damage any computer hardware, carefully consider the legal and ethical implications. There are almost always better options, like properly recycling old SSDs, that avoid legal trouble and benefit society.
Why Magnets Can Damage SSDs
SSDs store data in NAND flash memory chips made up of many tiny transistors. Each transistor acts as a data cell that uses an electrical charge to store either a 1 or 0, representing the binary data. The cells are arranged in blocks and pages to store data efficiently. When new data is written, the charge state of the cells change to represent the 1s and 0s of the data. To read the data, the chip’s controller checks the charge state of the cells.
Magnets can damage SSDs because their magnetic fields realign the transistors’ charge state. The strong magnetic force disrupts the alignment of positive and negative charges within the NAND flash memory cells, which changes the data they represent. Even brief exposure to a strong magnet can rearrange the electrical charges and scramble the SSD’s data. The extent of the corruption depends on the magnetic force. Weaker magnetic fields may only partially damage files, while very strong magnets can completely wipe all data from an SSD by randomizing the charge states.

Types of Magnets That Can Cause Damage
Not all magnets are strong enough to damage an SSD. The strength of the magnetic field is measured in teslas or gauss. According to this SuperUser post, magnets under 0.1 teslas are unlikely to cause damage. However, research indicates that magnets with a field strength of 1 tesla or higher could potentially damage SSD components.
Small fridge magnets are only around 0.01 teslas and are too weak to affect an SSD. Even most commercial or hobby magnets max out below 0.5 teslas. The strongest neodymium rare earth magnets can exceed 1 tesla, especially at their poles where the magnetic field is concentrated. Large electromagnets used in research can generate fields from 3-30+ teslas.
As for size, larger magnets tend to be more dangerous simply because their field affects a greater area. A tiny 1 tesla magnet may only damage components if placed in direct contact with the SSD circuitry. But a 10+ tesla research magnet could cause issues from a distance without even touching the drive.
In summary, watch out for high-powered rare earth magnets and large electromagnets, as these can generate the strong and widespread fields needed to damage SSD components if placed close enough.
Precautions for Proper SSD Use
Solid state drives (SSDs) are susceptible to damage from magnetic fields. Even common magnets like those found on refrigerator doors or magnetic tool holders can harm an SSD if brought too close. To prevent damage, it’s important to keep all magnets away from your computer and external SSD storage devices.
The specific components within an SSD that are vulnerable to magnets are the memory chips that store data. These chips operate by maintaining a precise electrical charge, which can be disrupted by magnetic fields. If the charge is altered, data loss and corruption can occur.
To be safe, keep any magnetic objects at least six inches away from your SSDs. Don’t place portable SSDs or laptops with internal SSD storage near magnetic items. Also avoid leaving SSDs unattended around potential magnetic hazards like speakers.
While basic precautions can prevent magnet-related failures, accidents do happen. If you suspect your SSD has been exposed to magnets and is malfunctioning, stop using it immediately and consult a data recovery service. They may be able to recover lost data before irreparable damage occurs.
With proper SSD handling, you can avoid the risks posed by magnets. Keep magnetic objects well away from SSD drives and enclosures to ensure reliable, long-term data storage.
Signs of SSD Failure from Magnet Exposure
While magnets do not physically damage SSDs, exposing an SSD to a strong magnetic field can corrupt data, leading to performance issues or failure. Some signs of SSD failure that may occur after magnet exposure include:
Performance issues: One of the most common signs is a dramatic slowdown in data transfer speeds, taking much longer to load or save files. This occurs as corrupted data on the SSD leads to more read/write errors and retries. The SSD’s controller has trouble accessing damaged blocks, significantly reducing performance.
According to one source, changes in magnetic fields may cause data loss if the SSD is actively reading or writing data during exposure. The disrupted operation leads to corruption of files or directory structures.
Overall, slowdowns, freezes, crashes, and problems accessing saved data point to magnet-related failure. However, physical damage is unlikely. Software solutions like updating firmware or low-level formatting may resolve the issues.
Data Recovery Options
If your SSD has been damaged by magnet exposure, professional data recovery services may be able to recover your data. Companies like DriveSavers and Secure Data Recovery specialize in recovering data from SSDs, even in cases of physical damage.
These professional services use specialized tools and techniques such as chip-off, microsoldering, and data extraction from SSD firmware in cleanroom environments. The process can be expensive but may be worth it for recovering irreplaceable data from a damaged SSD.
When evaluating data recovery services, be sure to look for companies that are experienced in SSD and flash recovery specifically. The cost for professional SSD data recovery can range from $500 to over $3000 depending on the severity of the damage.
Alternatives to Using Magnets
While magnets may seem like an easy way to quickly destroy an SSD, there are much better options that are legal and recommended for properly destroying drives.
The most secure way to destroy an SSD is to use a professional data destruction service. These services will shred or crush SSDs to completely destroy the physical drive and make data unrecoverable. Many companies like Verity Systems offer certified data destruction that provides a certificate of destruction.
For DIY destruction, disassembling the SSD and physically destroying the flash memory chips with a hammer or drill is an effective approach. However, this requires safely handling hazardous materials and should be done carefully.
Degaussing, which uses strong magnetic fields to disrupt data, is another non-destructive method. But effectiveness varies across SSD models and degaussing availability is limited.
Secure data erasure software can overwrite an SSD’s data to make it unrecoverable. Tools like Parted Magic offer this capability. However, software methods may be less reliable than physical destruction.
Before destroying any SSD, it’s important to fully backup its data if anything needs to be retained. With the right tools and precautions, you can securely destroy an SSD without resorting to magnets or other risky DIY approaches.
Proper SSD Disposal
When it comes time to dispose of an SSD, it is important to do so properly to protect sensitive data. The best option is to use a professional electronics recycling service that specializes in secure data destruction. Companies like Backblaze and iolo offer certified data destruction and environmentally-friendly recycling of old SSDs.
Recycling services will often degauss, shred, or otherwise physically destroy SSDs to permanently erase data. Some will provide a certificate of destruction once the process is complete. Using these professional services ensures your data cannot be retrieved from the old SSD once it is destroyed.
Compared to throwing an SSD in the normal trash or even recycling it without proper data destruction, using a dedicated electronics recycling service is the best way to safely dispose of an SSD. This method protects your sensitive information while also minimizing e-waste.
Conclusion
While strong magnets can certainly damage the data on an SSD, intentionally exposing any storage device to magnets is never recommended. SSDs contain complex hardware that is sensitive to magnetic fields. Even a brief exposure can corrupt files and render a drive unusable.
Rather than using magnets, it’s best to properly erase an SSD before disposal using software tools or the drive’s built-in secure erase command. If data recovery becomes necessary after accidental magnet exposure, professional services may help recover data, but results aren’t guaranteed.
In summary, SSDs should be handled with care to avoid any unintended damage. With the right precautions, solid state drives can reliably store data and serve for years as key components of computer systems.
