Built for university students at JKUAT, Kenyatta, and Moi who store lecture recordings, photographers backing up shoots between sessions, matatu and truck owners running dash cams along the Nairobi-Mombasa corridor, and small business owners feeding CCTV recorders, the SanDisk Ultra 128GB microSDXC solves one recurring problem: phones and recorders fill up fast, and cheap unbranded cards corrupt data or fail within months. At 128GB, this card stores roughly 24 hours of Full HD video, about 30,000 photos, or thousands of music tracks and apps before running out of room.

Unlike other electronics retailers in Kenya stocking unmarked cards with inflated capacity labels, the SanDisk Ultra 128GB microSDXC ships with verified SanDisk packaging, a genuine product code, and SanDisk's manufacturer limited warranty alongside a 6-month Mascom International warranty. Buyers across Kenya choose the SanDisk Ultra 128GB microSDXC because it survives water, drops, heat, and X-ray scanners, the four hazards that destroy data on lesser cards. Visit Mascom International to confirm the genuine SanDisk hologram before you buy, or order for countrywide pay-on-arrival delivery from our Kimathi Street store.

The SanDisk Ultra 128GB microSDXC holds about 119GB of usable space after formatting, since manufacturers count 1GB as 1,000,000,000 bytes while your device counts in binary. That usable space stores roughly 24 hours of Full HD 1080p video at standard bitrates, around 30,000 high-resolution phone photos, or more than 25,000 songs. For a dash cam recording loops, expect 10 to 15 hours before older footage overwrites. Actual figures shift with video resolution, bitrate, and photo size on your specific device.

The card reads at up to 100MB/s and meets UHS-I Class 10 and U1 standards, which guarantee at least 10MB/s sustained write speed for smooth Full HD video recording. Its A1 rating means a minimum of 1,500 random read and 500 random write operations per second, so apps moved to the card launch quickly. This card suits Full HD recording, phone storage, and dash cams, but 4K video cameras need a faster U3 or V30 card like the SanDisk Extreme instead.

The SanDisk Ultra 128GB microSDXC works with any device accepting microSDXC cards, including Samsung Galaxy A and M series phones, Tecno, Infinix, and Xiaomi handsets, Android tablets, Chromebooks, Windows laptops with card readers, GoPro and dash cams, and the Nintendo Switch. Older devices limited to 32GB microSDHC cards will not read this 128GB SDXC card. Newer iPhones lack microSD slots entirely. Check your device manual for microSDXC support if you are unsure before purchase.

Counterfeit SanDisk cards flood informal markets, often showing false 128GB labels over 8GB or 16GB chips that corrupt once filled. Genuine SanDisk Ultra cards from Mascom International carry sharp printing, a holographic authenticity mark, and a scannable code on the retail packaging. We recommend running H2testw or the F3 tool after purchase to confirm true capacity. Every card we sell ships in sealed SanDisk packaging, and our Nairobi CBD desk replaces any unit that fails a genuine capacity test.

The standard 100MB/s SanDisk Ultra retail pack at this price is the card-only version, which suits phones, tablets, and dash cams that take microSD directly. If your camera or laptop needs a full-size SD slot, Mascom International stocks SanDisk SD adapters and USB card readers separately at the store. Confirm your slot type before ordering. Tell our team whether you need an adapter, and we will pair the right accessory with your SanDisk Ultra 128GB microSDXC.

SanDisk Ultra cards are built to handle water, extreme temperatures, drops, and airport X-ray scanners, the conditions that wipe data on unbranded cards. The card tolerates humidity along the Mombasa and Diani coast, dust on Thika and Mombasa Road, and the heat inside a parked matatu or truck cab. This durability matters for dash cams left in vehicles all day and phones carried through dusty upcountry routes. The sealed chip design means no moving parts to fail.

At KSh 3,500, the SanDisk Ultra 128GB microSDXC costs about KSh 27 per gigabyte of tested, branded storage backed by warranty. Unbranded 128GB cards sell cheaper but routinely report false capacity and corrupt photos and videos within weeks, costing buyers far more in lost data. The SanDisk Ultra sits between budget no-name cards and the pricier SanDisk Extreme line. For phones, tablets, dash cams, and Full HD recording, this card gives the best balance of price, reliability, and speed.

After inserting the card, your Android phone prompts you to format it as portable storage for media or internal storage for apps and media combined. Internal storage formatting lets supported apps and their data live on the card, freeing the phone's built-in memory. The A1 rating keeps these apps responsive. The free SanDisk Memory Zone app from Google Play moves photos, videos, and files automatically to the card. Format choices and app-to-card support depend on your phone's Android version and manufacturer settings.

The SanDisk Ultra 128GB microSDXC carries a 6-month Mascom International warranty on manufacturing defects, alongside SanDisk's manufacturer limited warranty support. Our Nairobi CBD service desk handles any warranty claim or genuine capacity replacement directly, without requiring you to ship the card back to the manufacturer.
