Secure Digital (SD) memory cards are widely used in industrial and automotive applications, ranging from read-only applications—such as those found in navigation systems—to use as boot media, for video recording, or for data acquisition. Swissbit’s Industrial Secure Digital (SD) card series are designed for high sustained performance and longevity and are manufactured and tested in Swissbit’s in-house production facilities to withstand extreme environmental conditions.
The SLC-based S-600 offers maximum service life for applications where replacement intervals need to be extended. The new S-52 is aimed at automotive and video recording applications, while the S-50 is designed for typical use cases with high reliability requirements in industrial environments. The 3D pSLC version, the S-56, offers the best value for money.
