Note: price and availability are subject to change without prior notice
SanDisk microSD Express Card 256GB is in stock at Mascom International, priced at KSh 10,350, with read speeds up to 880MB/s and write speeds up to 650MB/s. It uses a PCIe NVMe interface, the same type of connection found inside laptop SSDs, which is why it runs several times faster than ordinary microSD cards. The card also carries U3 and V30 ratings for 4K video. Every unit is brand new and sealed under model code SDSQXFN-256G-GN4NN. Collect the SanDisk microSD Express Card at our store in the Old Mutual Building, Kimathi Street, Nairobi CBD.
Designed for Nintendo Switch 2 owners and other microSD Express devices, the SanDisk microSD Express Card 256GB solves a problem many gamers hit within weeks: the console's internal storage fills up, and Switch 2 accepts only microSD Express cards for extra games. Ordinary microSD cards will not work for that job. With 256GB, mobile gamers in Westlands or students at Strathmore can keep a large game library installed instead of deleting and redownloading titles over Safaricom Home Fibre. The card also works in phones, cameras and drones with standard microSD slots, running at UHS-I speeds there.
Where most Nairobi electronics shops still stock only standard UHS-I cards, Mascom International carries the SanDisk microSD Express Card for buyers who need the newer standard. Customers across Nairobi tell us they came in after buying a regular card that their Switch 2 refused to read. We explain the difference at the counter before you pay, so you leave with the right card for your console or camera. The SanDisk microSD Express Card is available for walk-in collection at Kimathi Street, or order on WhatsApp for pay-on-arrival delivery to any county in Kenya.
Common Questions About the SanDisk microSD Express Card
How much is the SanDisk microSD Express Card 256GB in Kenya?
The SanDisk microSD Express Card 256GB costs KSh 10,350 brand new and sealed at Mascom International in Nairobi CBD. That price includes the genuine SanDisk card, our 6-month warranty against manufacturing defects, and pay-on-arrival delivery anywhere in Kenya. An SD adapter is not part of the pack. If your device does not need microSD Express, the SanDisk Extreme PRO microSD Card 256GB costs KSh 9,500, which is KSh 850 less for the same capacity on the older UHS-I standard.
Does the Nintendo Switch 2 need a microSD Express card?
Yes, the Nintendo Switch 2 accepts only microSD Express cards for storing downloaded games, so the SanDisk microSD Express Card 256GB is the type it needs. Standard microSD cards, including fast UHS-I models, can be used only to view screenshots and videos copied from an older Switch, not to install games. Check for the "EX" or microSD Express logo on any card before you buy. At Mascom International, we confirm compatibility with your console at the counter so you avoid a wasted purchase.
Should I choose the SanDisk microSD Express Card or the SanDisk Extreme PRO microSD Card 256GB?
The SanDisk microSD Express Card 256GB uses a PCIe NVMe interface for reads up to 880MB/s, while the SanDisk Extreme PRO microSD Card 256GB uses the older UHS-I standard at much lower speeds. The Extreme PRO costs KSh 9,500 and suits drones, phones and action cameras that only read UHS-I. Pick the microSD Express Card if you own a Nintendo Switch 2 or another microSD Express device. Pick the Extreme PRO if you never will, and save KSh 850.
Will the SanDisk microSD Express Card work in my phone or drone?
Yes, the SanDisk microSD Express Card is backward compatible with UHS-I devices, so it fits phones, drones and cameras that accept microSDXC cards. In those devices it runs at UHS-I speeds, not the full 880MB/s, because the host device sets the speed limit. Full speed needs a microSD Express host or a microSD Express card reader. If you only plan to use the card in an Android phone, the SanDisk Extreme GO microSD Card 128GB at KSh 4,500 gives you better value.
Can the SanDisk microSD Express Card survive Kenyan heat, dust and rain?
The SanDisk microSD Express Card is rated to operate from -25°C to 85°C, well beyond the heat of a parked car in Mombasa or Garissa. SanDisk also lists it as waterproof, shock-proof, drop-proof, magnet-proof and X-ray-proof, so airport scanners at JKIA do not harm your data. Dust is no threat to the card itself, though grit in a console slot can block contact. Keep the card in a case when travelling and wipe the slot area with a dry cloth.
How many Nintendo Switch 2 games fit on the SanDisk microSD Express Card 256GB?
The SanDisk microSD Express Card 256GB holds several large Switch 2 games, though the exact count depends on each title's download size, which varies widely. Smaller indie games take only a few gigabytes, so a mixed library can run to dozens of titles. Remember that the card's usable space after formatting is slightly below 256GB. Mobile gamers in Nairobi tell us the extra room saves them from redownloading games over home fibre or Safaricom data every few weeks.
Do I need a special reader to copy files from the SanDisk microSD Express Card to a laptop?
To reach the full 880MB/s read speed, the SanDisk microSD Express Card needs a microSD Express card reader connected to a fast USB port. In a normal UHS-I laptop slot or reader, it still works, just at UHS-I speeds. Content creators editing in Kilimani studios who also record on this card should pair it with an Express reader. For Switch 2 owners who never move files to a computer, no extra reader is needed at all.
Who should buy the SanDisk microSD Express Card 256GB and who should skip it?
The SanDisk microSD Express Card 256GB is the right buy for Nintendo Switch 2 owners and anyone with a microSD Express device or reader. Skip it if your phone, drone or camera only supports UHS-I, because you will pay for speed the device cannot use. Those buyers should pick the SanDisk Extreme PRO microSD Card 256GB at KSh 9,500 or the SanDisk Extreme GO microSD Card 128GB at KSh 4,500. Casual phone users do fine with the SanDisk Ultra GO microSD Card.

Package Contents
The SanDisk microSD Express Card 256GB comes in SanDisk's sealed retail pack with the card inside.
