SanDisk Ultra 256GB microSDXC is now in stock at Mascom International for KSh 5,500, available at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD. This UHS-I Class 10 card reads at up to 100MB/s, carries an A1 app rating, and ships with a full-size SD adapter in the box. The SanDisk Ultra 256GB adds room for roughly 59,000 photos or more than 30 hours of Full HD video to any microSD-ready phone, tablet, camera, or Chromebook. Mascom International stocks genuine SanDisk stock with pay-on-arrival delivery to all 47 counties.
The SanDisk Ultra 256GB microSDXC suits Kenyan content creators, photographers, university students, and field professionals who fill up phone storage faster than they expected. A 64GB or 128GB phone runs out of space after a few months of WhatsApp media, TikTok clips, and weekend photos. This card solves that without forcing you to delete memories or pay for cloud subscriptions. Drop it into a microSD slot, move your gallery and offline music across, and free up internal storage for apps and updates in minutes.
Buyers across Kenya rely on Mascom International for genuine SanDisk cards, not the counterfeit memory that floods informal markets. The SanDisk Ultra 256GB microSDXC carries SanDisk's own 10-year limited manufacturer warranty, backed locally by Mascom International's after-sales desk in Nairobi CBD. Walk into our Kimathi Street store to test the card in your device before you pay, or order by phone and inspect it on arrival. At KSh 5,500, the SanDisk Ultra 256GB is one of the most cost-effective storage upgrades available through Kenya's electronics retailers today.
Common Questions About the SanDisk Ultra 256GB microSDXC
Is the SanDisk Ultra 256GB fast enough to record video on my phone?
Yes, the SanDisk Ultra 256GB microSDXC handles Full HD 1080p video recording without dropped frames on most phones. Its Class 10 rating guarantees a minimum sustained write speed of 10MB/s, which covers standard 1080p capture on Samsung, Tecno, Infinix, Xiaomi, and Oppo handsets. Read speeds reach up to 100MB/s, so transferring clips to a laptop stays quick. For continuous 4K video on high-end phones or action cameras, the SanDisk Extreme line with a V30 rating is the better match. For everyday phone recording, this card keeps up comfortably.
How many photos and videos can the SanDisk Ultra 256GB microSDXC hold?
The SanDisk Ultra 256GB microSDXC gives you about 238GB of usable space after formatting. That stores roughly 59,000 photos at 4MB each, the typical size of a 12-megapixel phone shot. The same card holds more than 30 hours of Full HD 1080p footage, or tens of thousands of music tracks for offline playback. Content creators in Nairobi can shoot a full wedding or event without swapping cards mid-shoot. Students can carry years of lecture recordings, PDFs, and project files on a card smaller than a fingernail.
Will the SanDisk Ultra 256GB microSDXC work with my phone, tablet, and camera?
The SanDisk Ultra 256GB microSDXC works with any device that has a microSD card slot and supports SDXC cards up to 256GB or higher. That covers most Android phones, Samsung and Xiaomi tablets, Chromebooks, dash cameras, and many compact cameras and drones. The bundled SD adapter lets you slot the card into laptops, DSLRs, and card readers that use the full-size SD format. Check your device manual for the highest supported card size before buying. SanDisk tests these cards across thousands of devices common in the Kenyan market.
Is the SanDisk Ultra 256GB microSDXC good for the Nintendo Switch or mobile gaming?
The SanDisk Ultra 256GB microSDXC stores Switch game downloads and screenshots, but its write speed is built for media rather than heavy gaming. For storing and launching games, the A1 rating helps apps and titles open faster through 1500 read input-output operations per second. Hardcore Switch users who download large titles often may prefer a U3 or A2 card for quicker installs. For casual gaming, app storage, and saved files, this card does the job at a lower price. Mascom International also stocks faster cards if your workload demands them.
What does the A1 rating on the SanDisk Ultra actually mean for apps?
The A1 rating means the SanDisk Ultra 256GB is tuned for running apps directly from the card, not just storing files. A1 guarantees 1500 read and 500 write input-output operations per second, so apps moved to the card launch and respond faster than on slower memory. On Android phones that allow apps on external storage, this keeps games and tools usable instead of sluggish. The rating matters most on budget phones with limited internal storage, where shifting apps to the card frees up space and keeps the system responsive.
Is the SanDisk Ultra 256GB microSDXC worth KSh 5,500 in Kenya's market?
At KSh 5,500, the SanDisk Ultra 256GB microSDXC costs far less than upgrading to a phone with more built-in storage. Moving from a 128GB to a 256GB phone often adds KSh 8,000 or more to the handset price. This card adds the same capacity for a fraction of that, and you can move it between devices when you upgrade. Genuine SanDisk stock from Mascom International also avoids the fake cards that show false capacity and corrupt your files. The 10-year manufacturer warranty makes the price easy to justify.
How does the SanDisk Ultra compare to the SanDisk Extreme?
The SanDisk Ultra 256GB targets everyday storage and Full HD video, while the SanDisk Extreme targets 4K video and demanding cameras. The Ultra reads at up to 100MB/s with a U1 and A1 rating, suited to phones, tablets, and casual recording. The Extreme reads faster, carries a U3 and V30 rating, and sustains the higher write speeds that 4K and action-camera footage need. For most phone and tablet users in Kenya, the Ultra offers better value. Photographers and videographers shooting 4K should step up to the Extreme.
Can the SanDisk Ultra 256GB microSDXC survive dust, water, and heat?
Yes, the SanDisk Ultra 256GB is built to handle rough conditions across Kenya. SanDisk rates the card as waterproof, temperature-proof, shockproof, X-ray-proof, and magnet-proof. That means it holds your data through accidental drops, dusty Thika Road commutes, and the heat of Mombasa, Kisumu, and Lodwar. A short fall from a desk or a soak from an unexpected Nairobi downpour will not wipe your photos. These ratings explain why field professionals and travellers trust the card in conditions that would damage cheaper memory.
