- Write-Conce Memory Card offers manipulation-proof, long-term data storage
- TeamGroups 256 GB D500R WORM SD -Cards can save up to 374 CDS ‘values of data
- Built -in protective functions protect against power loss, damage and manipulation
CDS and DVDs are (or rather said) good for storage, but they can be affected by the discrice, a form of physical deterioration that affects optical disks, causing them to become illegible over time due to corrosion or damage to the reflective layer. If you have a lot of important data stored on disks and are worried about losing them, Teamgroup has a solution to your fears – D500R ISD WORM SD card.
Viewed on Embedded World 2025 (where it won the embedded Vision category’s Top Honor and 2025 Community Choice Award), uses the D500R Worm card once, reads many technologies for non-slot, manipulated sets, long-term data storage storage.
D500R ISD uses MLC NAND FLASH which provides better durability and stable performance, and lifts reading and writing speeds of up to 70 MB/s and 65 MB/s. It supports capacities from 8 GB to 256 GB. The biggest card is large enough to store data from about 374 CDs, so it can probably take up all your disks.
Seal the data in place
As you can tell from the description, the card can be read many times, but only written for once. Via a combination of hardware design and firmware control, the D500R ISD is sealing the data in place and ensures that they cannot be deleted, overwritten or updated. This makes it useful for users who need lasting data protection without the risk of accidental changes or even malicious manipulation from ransomware.
The card includes features such as Power Fail Management that help maintain data in the event of an unexpected power outage and poor block control that detects and insulates defective storage sectors, which helps expand the product’s life.
It also has a built -in smart system that tracks use and sends warnings if an attempt is made to change or delete the data in some way.
Built to withstand demanding environments, it meets several shocks from military quality and vibration standards and is classified IP58 for dust and water resistance.
TeamGroup suggests that it may be useful for recording law enforcement, medical items or financial archives, but it can be used for backing up family photos and videos or company data.
While it is clearly a fantastic solution for long-term archive storage, it is probably worth noting that the D500R worm card is much easier to lose than a box of CDs or DVDs, so you might think about where you keep it. There is also no word about pricing yet, but it is fair to assume that it will not be cheap.
