SanDisk Extreme SD UHS-I Card Price in Kenya & Full Review The SanDisk Extreme SD UHS-I Card price in Kenya is KSh 5,000 Original price was: KSh 5,000.KSh 4,000Current price is: KSh 4,000.. It is a high-performance full-size SD memory card designed for photographers, videographers and content creators who need faster recording and file-transfer performance than a standard SD card. It supports UHS-I, U3 and V30 specifications, making it suitable for compatible cameras that record 4K UHD video and high-resolution still images. Depending on capacity, sequential read speeds reach up to 180MB/s, while write speeds reach up to 130MB/s. The highest 180MB/s read performance requires a compatible device and SanDisk’s specified high-speed reader setup; actual performance depends on the host device, card reader and usage conditions. Fast UHS-I Performance The SanDisk Extreme SD uses a UHS-I interface and is designed for faster image capture and file transfers. The current Extreme SD range reaches up to 180MB/s read speed on 128GB, 256GB and 512GB versions. The 64GB model reaches up to 170MB/s, while the 32GB model reaches up to 100MB/s. For the 256GB and 512GB versions, write performance reaches up to 130MB/s. The 128GB version supports up to 90MB/s write speed, 64GB up to 80MB/s, and 32GB up to 60MB/s. These are maximum sequential figures under SanDisk’s testing conditions rather than guaranteed everyday transfer speeds. Designed for 4K UHD Video The U3 and V30 ratings make the SanDisk Extreme suitable for supported 4K UHD video recording. V30 specifies a minimum sustained video-write performance of 30MB/s under the Video Speed Class standard, while U3 indicates a UHS performance class designed for 4K UHD recording on compatible UHS-enabled devices. This makes the card particularly useful for DSLR and mirrorless cameras, camcorders and other devices that require a full-size SD card for continuous video recording or burst photography. High-Resolution Photography Fast write performance helps the card handle continuous or burst shooting more effectively than slower Class 10 cards. This is useful for photographers capturing sports, wildlife, events, travel and other subjects where several high-resolution images may be written to the card in quick succession. Large Storage Capacities The SanDisk Extreme SD is offered in 32GB, 64GB, 128GB, 256GB and 512GB capacities. The larger 256GB and 512GB versions are particularly useful for photographers and videographers who regularly record large RAW photo files or extended 4K video sessions. Durable Construction The card is designed and tested for demanding environments. SanDisk lists the Extreme SD as waterproof, temperature-proof, shock-proof and X-ray-proof. SanDisk also describes its SD cards as resistant to additional environmental stresses including drops, magnets, humidity and wear. Its operating temperature range is approximately -25°C to 85°C, while the storage temperature range is approximately -40°C to 85°C. Built-In Write Protection A physical write-protect switch is built into the SD card. When enabled, it helps prevent files from being accidentally modified or deleted, which is useful when transferring or archiving important photographs and videos. Fast Transfers with SanDisk QuickFlow The 64GB–512GB versions support SanDisk QuickFlow technology for read speeds of up to 180MB/s when paired with compatible equipment. SanDisk specifies that maximum performance requires a compatible high-speed reader, such as the SanDisk Professional PRO-READER SD and microSD. Without compatible hardware, actual transfer speeds can be lower.
