At Mascom International, we're seeing demand rise for high-capacity cards as Kenyan creators shoot more Full HD video for YouTube, TikTok, and client work.

Common Questions About the SanDisk Ultra SDXC 512GB

Is the SanDisk Ultra SDXC 512GB worth KSh 10,000 in Kenya?
Yes, for anyone who shoots photos or Full HD video and keeps running out of space. KSh 10,000 works out to roughly KSh 20 per gigabyte, fair pricing for a 512GB card from a known brand. Cheaper no-name cards often report false capacity and corrupt files after a few weeks. The SanDisk Ultra SDXC 512GB pairs a verified 512GB with a 10-year limited warranty, which protects the cost over years of use across multiple cameras and devices.

Which cameras and devices work with the SanDisk Ultra SDXC 512GB?
The SanDisk Ultra SDXC 512GB fits any device with a full-size SD card slot. This covers most DSLR and mirrorless cameras from Canon, Nikon, and Sony, plus camcorders, dash cameras, and many laptops. Check that your device supports SDXC and 512GB capacities, since older cameras may cap at 32GB or 256GB. Drones and action cameras usually need microSD instead. Bring your device to our Nairobi CBD store and we will confirm compatibility before you pay.

How many photos and how much video fit on 512GB?
A 512GB card holds a large amount of work. Expect roughly 90,000 high-resolution JPEG photos at typical 24-megapixel file sizes, though raw files take far more space. For video, plan on around 70 hours of Full HD 1080p footage at standard recording bitrates. Actual counts depend on your camera settings, file format, and compression. Either way, the SanDisk Ultra SDXC 512GB removes the need to swap cards during a full wedding, conference, or weekend shoot.

Is the SanDisk Ultra SDXC 512GB fast enough for 4K video?
The SanDisk Ultra line targets Full HD recording and photography, not sustained 4K. Its U1 and Class 10 rating guarantees a minimum 10MB/s write speed, which handles 1080p video and burst photos well. High-bitrate 4K recording needs a U3 or V30 card, such as the SanDisk Extreme range. If your work is mostly photos and Full HD video, the SanDisk Ultra SDXC 512GB is a sound match. For heavy 4K, ask us about the Extreme cards in stock.

How fast does the SanDisk Ultra SDXC 512GB transfer files?
Read speeds reach up to 150MB/s, so moving files off the card to a computer is quick. Transferring around 1,000 photos can take roughly one minute with a compatible card reader and a fast computer port. This saves real time when you return from a shoot and need to back up, edit, and deliver client work the same day. Write speed during recording stays above the 10MB/s minimum guaranteed by the U1 rating.

How do I know the SanDisk Ultra SDXC 512GB is genuine and not a fake?
Counterfeit memory cards are common in Kenya, often sold with fake capacity labels that corrupt your files once full. Mascom International sources the SanDisk Ultra SDXC 512GB through verified supply channels, and our pay-on-arrival terms let you inspect the card first. We can run a free capacity test in-store to confirm the full 512GB before purchase. The 10-year SanDisk limited warranty only applies to genuine units, which is another reason buyers across Nairobi choose a trusted seller.

How does the SanDisk Ultra compare to the SanDisk Extreme?
The SanDisk Ultra is the value option built for photos and Full HD video, while the SanDisk Extreme targets 4K video and faster action shooting. The Ultra carries a U1 rating with up to 150MB/s read; the Extreme adds U3 and V30 ratings with higher sustained write speeds for 4K. If your camera mostly shoots stills and 1080p clips, the Ultra saves money. If you record 4K regularly, the Extreme is the safer choice. Mascom International stocks both.
