SanDisk microSDXC Express 256 GB (SDSQXFN-256G-GN4NN)

High-performance compact 256 GB memory card supporting both the advanced microSD Express standard and the traditional microSDXC UHS-I. Positioned as an upper mid-range product, it targets demanding users, enthusiasts, and professional content creators. The PCIe Gen3 NVMe bus interface offers performance comparable to standard portable SSDs, meaning that using it, the read/write speed will be four times higher than the fastest microSD UHS-I cards.

For example, using a SanDisk PRO-READER SD Express Dual card reader (sold separately) allows for reading a 4 GB UltraHD/4K video file faster than 6 seconds. The SanDisk microSDXC Express 256 GB memory card is compatible with the Nintendo Switch 2 and several other portable gaming consoles, making it easy to expand their permanent memory. It can be used in UltraHD/4K/6K resolution digital video cameras.

It also performs well in high-speed professional DSLRs and mirrorless cameras during rapid burst shooting in RAW and JPG formats. The significant 256 GB capacity allows users to focus on the creative process without the distraction of changing cards. SanDisk ThermAdapt technology helps protect devices from overheating with a special heat-dissipating case and a controller with adaptive temperature management.
