When you shop memory batteries power for your camera, the real question is which format and capacity actually fit your device. Four SanDisk cards are on the table: a 2GB card for older cameras, two 256GB cards, and a 512GB microSDXC with an SD adapter. The full-size SD cards and the microSD card are not interchangeable, so the right pick starts with the slot your camera has.
Quick Take
You're choosing between a small 2GB card for a legacy camera, two matching 256GB cards, and a 512GB microSDXC with an adapter. The format question comes first: full-size SD or microSD. The 2GB card is the only one aimed at older non-SDHC cameras. The two 256GB cards are the middle-ground choice, and the 512GB card is for anyone who needs maximum storage.
The 512GB ImageMate is a microSDXC card with an SD adapter, so it can go into a microSD device or a full-size SD slot with the adapter. The other three cards are full-size SD. That format split is the first thing to sort out before price or capacity enters the picture.

Product Notes
256GB SD Cards SanDisk High Endurance! 150 Left

This is one of two 256GB SanDisk High Endurance cards at the same $40.00 price. It's a new, full-size SD card with a Class 10 speed rating and compatibility with universal brands and models. If you want a large but not maximum capacity for a modern camera, this is a clean middle option. The reason to pick it is the balance of 256GB storage and faster speed class for the price. The limitation is the format: it's an SD card, not a microSD card, so it won't fit devices that only accept microSD.
256GB SD Cards SanDisk High Endurance

This second 256GB SanDisk High Endurance card is effectively the same product as the first: $40.00, new condition, full-size SD format, and 256GB capacity. If both are in your comparison, treat them as interchangeable. The reason to choose this one is the same storage and performance at the same listed price, so you can go with whichever title you prefer. The limitation is that 256GB is the ceiling here, and if you need more room, the 512GB ImageMate is the step up.
SanDisk ImageMate 512GB microSDXC UHS-I Flash Memory Card w/ SD Adapter

At $59.99, the ImageMate is the highest-priced card in this group, and it has 512GB of storage. It's a new microSDXC card with an included SD adapter that lets you use it in full-size SD slots as well as microSD slots. The reason to choose it is capacity: if 256GB isn't enough, this is the only card in this group that goes higher. The limitation is the price gap over the 256GB cards, so it makes sense only if you actually need the extra room.
SanDisk 2GB SD Card Class 2 Camera Memory works with digital cameras NIKON

This card is the odd one in the group: used, full-size SD, 2GB capacity, and a Class 2 speed rating, but priced at just $12.99. Its reason to exist is compatibility with older cameras, specifically the Nikon D50. If you have one of those older cameras that requires a non-SDHC 2GB card, this is the card to consider. The limitation is clear: 2GB is very small and Class 2 is slow, so it's not a card for storing a large photo collection.
Final Recommendation by Use Case
For a modern camera that takes full-size SD cards, the 256GB SanDisk High Endurance card is the balanced pick: enough room for typical shooting without paying for 512GB. For a device that takes microSD or when maximum capacity is the priority, the SanDisk ImageMate 512GB with SD adapter is the one to get. For an older non-SDHC camera, the SanDisk 2GB Class 2 card is the practical fit. Start with the card that matches your camera slot, then let capacity decide.
