Review: These are EXCELLENT cards if your device isn't up to UHS II standards. - I purchased these in hopes of getting the most out of my Nikon D7100 on a trip to Alaska, and they didn't disappoint. They didn't solve the issue I was chasing (Frames Per Second and the Memory Buffer) but I didn't expect them to either. What they did do is perform perfectly. Over 3300 pictures without any data compromise. They were instantly recognized by my camera upon insertion and formatted fine. Transfer to a PC is with speeds as expected depending on your interface. Write speeds are more than enough for my use case. They even work in my Nikon D500 but I'm not using them there as I'm moving to UHS II cards for that (and NVME with a CFeB adapter).
Review: Reliable and high capacity: Great for photos - Excellent card; this brand is very reliable. I was able to store many photos, and I highly recommend it.

### ⭐⭐⭐⭐⭐ These are EXCELLENT cards if your device isn't up to UHS II standards.
*by S***L on February 22, 2026*

### ⭐⭐⭐⭐⭐ Reliable and high capacity: Great for photos

Excellent card; this brand is very reliable. I was able to store many photos, and I highly recommend it.

### ⭐⭐⭐⭐⭐ Reliable, Fast, and Worth Every Penny
*by A***N on January 30, 2026*

⭐⭐⭐⭐⭐ Reliable, Fast, and Worth Every Penny I’ve been using this SanDisk Extreme PRO 128GB SDXC card for all my photo and video needs, and it’s been fantastic. The storage capacity is generous — plenty of room for high-resolution photos, long 4K videos, and lots of travel footage without having to swap cards constantly. Users consistently praise its speed and reliability, especially when shooting in burst mode or recording UHD video. 📸 Performance: The card delivers fast read and write speeds that make transferring files quick and smooth, and it handles demanding tasks like 4K video and rapid-fire shooting without hiccups. 💪 Durable Build: Like other SanDisk Extreme PRO cards, this one is built to endure — it resists water, shock, x-rays, and extreme temperatures, so I don’t worry when I take it into rugged conditions. 👍 Compatibility: It works flawlessly with a variety of cameras, from DSLRs to mirrorless bodies and drones — plug-and-play performance every time. My only suggestion is to buy from reputable sellers to avoid counterfeit cards, as that can be an issue on some marketplaces. But if you get the genuine product, this card is well worth the investment and a great choice for both enthusiasts and pros.
