256GB SDXC Card for DSLR and Camcorder Users
This Transcend 340S card provides 256GB of SDXC storage designed for UHS-I compliant DSLR cameras and camcorders. It targets photographers and videographers who need reliable capacity for high-resolution stills and 4K video. The A1 rating supports app performance on compatible mobile devices.
UHS-I Interface Limits Read to 160MB/s
The UHS-I bus caps maximum transfer rates at 160MB/s read and 90MB/s write, so sustained throughput cannot exceed these figures. V30 and U3 ratings guarantee a minimum 30MB/s sequential write for uninterrupted 4K capture. Class 10 ensures 10MB/s baseline performance for Full HD recording.
Verify Your Device Supports SDXC
Check that your camera or camcorder accepts SDXC cards and can utilise UHS-I speeds for the stated performance. Devices limited to SDHC or non-UHS buses will not reach the advertised read or write rates. Confirm 4K recording requirements match V30 minimum sustained write capability.
