Product Description
The Lexar High-Performance 633x 128GB microSDXC UHS-I card (LSDMI128BB633A) is an expanded-capacity, high-speed flash memory solution designed for action camcorders, tablets, smartphones, aerial drones, and handheld gaming consoles. Utilizing UHS-I bus architecture to deliver sustained read transfer speeds of up to 100 MB/s (633x), this card significantly reduces workflow bottlenecks when transferring high-resolution photographs, extensive video reels, and multi-gigabyte project directories to PCs or post-production workstations.
Certified to Video Speed Class 30 (V30) and UHS Speed Class 3 (U3) standards, the 128GB 633x maintains a guaranteed minimum continuous sequential write floor of 30 MB/s, with peak burst write speeds reaching up to 45 MB/s. This sustained performance prevents frame drops, buffer lag, and stuttering during extensive 1080p Full HD, 3D, and 4K UHD video recording across action cameras, gimbal systems, and camera-equipped quadcopters. The generous 128GB capacity offers considerable storage overhead to record hours of high-bitrate footage, store expansive music and multimedia collections, or expand mobile device memory without constant data offloading.
Rated Application Performance Class 2 (A2), the card delivers swift random read/write IOPS, enabling faster app launch times, smooth data execution, and reliable background loading when running mobile applications or storing titles on portable gaming systems like the Nintendo Switch. Tested under rigorous conditions in Lexar Quality Labs, the card features robust multi-proof protection against water immersion, extreme ambient operating temperatures, physical shock, vibrations, and airport X-ray inspection. Equipped with a dedicated full-size SD adapter for universal compatibility with standard camera slots, the Lexar High-Performance 633x 128GB microSDXC card delivers a dependable, high-capacity mobile storage solution.
