- The Write-Once memory card offers long-term data storage to manipulation proof
- Teamgrup 256 GB SD SD card can store up to 374 CDs in data
- The protection characteristics incorporated are loss of power, damage and manipulation
CDs and DVDs are (or rather) excellent for storage, but they can be affected by disk rot, a form of physical deterioration that affects optical discs, which causes them to become insecible over time due to corrosion or damage to the reflective layer. If you have many important data stored on the records and worry about losing them, Teamgroup has a solution to your fears: the D500R ISD Worm SD card.
Showed in IncreddDed World 2025 (where he won the main honor of the integrated vision category and the 2025 community choice award), the D500R worm card uses Write once, read many technologies for the storage of long -term data retention not prior, manipulation proof of long term.
The D500R ISD uses MLC Nand Flash, which offers better durability and constant performance, and promises reading and writing speeds of up to 70 MB/Sy 65 Mb/s. Admits 8 GB capabilities to 256 GB. That larger card is large enough to store data of around 374 CD, so it is likely to back up all its albums easily.
Seal the data instead
As you can see in the description, the card can be read many times, but it is only written once. Through a firmware hardware and control design combination, the ISD D500R seals the data in place and ensures that it cannot be deleted, overwritten or updated. This makes it useful for users who require durable data protection without the risk of accidental changes or even the malicious manipulation of ransomware.
The card includes features such as Power Fail Management, which helps preserve data in case of unexpected energy and incorrect block management, which detects and isolates the defective storage sectors, helping to extend the life of the product.
It also has an intelligent incorporated system that tracks use and sends alerts if you try to alter or delete data in some way.
Built to support demanding environments, it meets multiple shock standards and military grade vibration and is classified as IP58 for dust and water resistance.
Teamgroup suggests that it could be useful for images of application of the law, medical records or financial archives, but could be used to support family photos and videos or data of the company.
While it is clearly a great solution for long -term file storage, it is probably worth noting that the D500R worm card is much easier to lose than a CD or DVD box, so it is possible to think about where you will keep it. Nor is there a word about prices, but it is fair to assume that it will not be cheap.
