This Kingston SDCS2 card provides 256GB of storage in a microSD form factor. It is suited for smartphones, tablets, digital cameras and dashcams. The card carries an A1 rating for application performance. Buyers who need larger capacities or different form factors should look elsewhere.

Questions about this item

Does the SDCS2 MicroSD card run hot or draw noticeable power during continuous full HD recording?

The card uses UHS-I Class 10 with V30 rating, so it sustains 30 MB/s write speeds for full HD video without generating excess heat or drawing high power.

What host device slot and speed class are required to use the 256 GB SDCS2 at its rated performance?

A microSDXC slot supporting UHS-I and at least Class 10 / U3 / V30 is needed; the card is A1 rated for Android app performance.

Will the SDCS2 work reliably in an older dashcam or camera that only supports Class 10 or UHS-I speeds?

Yes, the card is backward compatible with Class 10 and UHS-I hosts and will operate at the maximum speed the older device allows.
