- The Write-Once memory card offers long-term data storage to the test
- The WORM SD SD card of 256 GB of Teamgroup can store up to 374 CDS of data
- Integrated protection characteristics keep loss of power, damage and falsification
CDs and DVDs are (or rather) excellent for storage, but they can be affected by disc rot, a form of physical deterioration that affects optical discs, which makes them illegible over time due to corrosion or damage to the reflective layer. If you have a lot of important data stored on the discs and you fear losing it, Teamgroup has a solution to your fears – the SD WORM ISD D500R card.
Showed in the integrated world 2025 (where he won the Top Honor in the Vision Embedded category and the price of Community choice 2025), the D500R verse card uses once, read many technologies for the storage of long -term non -oustable and inviolable long -term data.
The D500R ISD uses MLC Nand Flash, which offers better sustainability and regular performance, and promises reading and writing speeds up to 70 MB / s and 65 MB / s. It supports the capacities from 8 GB to 256 GB. This largest card is large enough to store data of around 374 CDs, so it can probably save all your discs easily.
Seal the data in place
As you can see from the description, the card can be read several times, but only written at once. Via a material design and control combination of the firmware, the D500R ISD seals the data in place and guarantees that it cannot be deleted, crushed or updated. This makes it useful for users who need sustainable data protection without risk of accidental modifications or even malicious falsification of ransomware.
The card includes features such as Power Fail Management, which helps preserve the data in the event of an unexpected supply cut, and mismanagement of blocks, which detects and isolates the defective storage sectors, helping to extend the life of the product.
It also has an integrated intelligent system which follows the use and sends alerts if an attempt is made to modify or delete the data in one way or another.
Built to resist demanding environments, it meets several military quality shock and vibration standards and is classified IP58 for resistance to dust and water.
Teamgroup suggests that it could be useful for law enforcement sequences, medical files or financial archives, but it could be used to save family photos and videos or business data.
Although this is clearly an excellent solution for the storage of long-term archives, it should probably be noted that the D500R verse card is much easier to lose than a box of CD or DVD, you may want to think about where you will keep it. There is no words on prices either, but it is just to assume that it will not be cheap.
