Choosing a memory card for your camera usually comes down to two questions: how much room do you need for photos and video, and how fast do you want file transfers to be? Both cards here use the SDXC UHS-I format, so they are aimed at devices that accept that card type, and both carry the SanDisk name. The Extreme Pro 128GB is a new-condition card that makes speed its headline feature, while the Ultra PLUS 512GB is an open-box card that puts capacity first. Both list universal compatibility, so the real decision is whether you value a new, speed-oriented card or a much larger storage space.
Quick verdict
If your shooting sessions are long and you would rather not swap cards, the Ultra PLUS gives you far more room at a $10.80 higher listed price. If you shoot in bursts or offload files often, the Extreme Pro's higher transfer rating will cut down on waiting time. If you prefer a new card and don't need maximum storage, the Extreme Pro is the more straightforward pick. The trade-off is simple: more capacity for a slightly higher price, or a new condition at a lower listed price.

Product notes
SanDisk Extreme Pro 128GB 200mb/S SDXC UHS-I Memory Card
This card is listed as new and carries the Extreme PRO series name. It is a solid choice when you want to start with a new-condition card and keep file transfers quick in daily use. For a shooter who mostly works with one card per session and backs up soon after shooting, this is a clean fit. The practical limitation is storage: this card holds less data than the Ultra PLUS, so you will need to offload files sooner during a long session. If your priority is a new-condition card with a speed-oriented design, this one fits.
SanDisk - Ultra PLUS 512GB SDXC UHS-I Memory Card
The Ultra PLUS is the capacity pick. With 512GB of storage, it gives you roughly four times the space of the 128GB Extreme Pro, which is ideal for long shoots and large video libraries. It also lists water resistance, so it can handle damp conditions without as much worry. For a shooter who wants to minimize card swaps and keep everything on one card, this is the one to carry. The trade-off is condition: this card is open box, so it may not be in the same pristine retail state as the new Extreme Pro. If capacity matters more than having a new-condition card, this is the better choice.
Final choice by use case
Choose the SanDisk Extreme Pro 128GB when you prefer a new card and don't need a huge amount of storage. Choose the SanDisk Ultra PLUS 512GB when you want maximum capacity and are comfortable with an open-box condition.
