SanDisk Ultra GO SDXC 128GB 190MB/s memory card

128GB SDXC card for cameras

This SanDisk Ultra GO SDXC card provides 128GB of storage for cameras and other devices that accept the SDXC format. It is rated for full HD video recording and carries A1, Class 10, U1 and V10 speed class markings. The card uses NAND flash technology and is built to withstand water, X-rays, shock and magnets. It suits photographers and videographers who need reliable media for everyday shooting.

UHS-I bus caps sequential reads

The card operates on the UHS-I interface, which limits maximum sequential read performance to the bus ceiling. The stated read speed reaches up to 190MB/s, but sustained write throughput is governed by the V10 video speed class, guaranteeing a minimum of 10MB/s. Devices that only support older SD specifications will fall back to lower speeds. Buyers needing guaranteed write rates above 10MB/s for higher bitrate codecs should note this constraint.

128GB fits hours of full HD footage

At 128GB the card holds many hours of full HD video and thousands of high-resolution photos, giving ample headroom for a day of typical shooting. The V10 rating ensures consistent performance for standard full HD bitrates, but it does not sustain the write speeds required for 4K or high-frame-rate recording. Users capturing those formats will run out of write bandwidth before they run out of capacity.
