There is no interesting technical difference between this card and the SanDisk Extreme of the same size, and pretending otherwise would be inventing one.

The honest comparison

Both are 256 GB. Both are general purpose rather than endurance rated. Both quote a read speed that a camera never uses. Both include an adapter. Buy whichever is cheaper or in stock on the day.

What would actually be a better card

One sold as high-endurance, rated in hours of continuous recording rather than in megabytes per second. That is the card for a camera writing 24 hours a day, and neither of the 256 GB cards on this page is one.

Neither listing claims to be. The assumption is usually the buyer’s.

The camera check

Confirm your camera accepts 256 GB before ordering. Older models stop at 128, and that limit is in the manual rather than on the card.

Availability

On sale at $67 on the American Amazon store at the time of checking.

Prices and availability are what Keepa reported on the date this page was updated; both move.

The questions we are asked

How do I choose between this and the SanDisk?

On price on the day and on stock. Neither is endurance rated, both are 256 GB, and both write far faster than a camera needs. There is no meaningful technical difference to decide on.

Is there an endurance card I should buy instead?

For continuous recording, yes — cards sold as high-endurance and rated in hours of continuous recording. Neither card on this page is one, and both listings are honest about what they are. It is the buyer who usually assumes otherwise.
