Will this card work for a cobra 4 channel security system the instructions say i need a 256gb sd card?

Works well in my sony camera, if the ccs says 256gb this should work.

How many pictures will this hold

Depends on what resolution you are using.

Can I use this memory card for canon eos t7 camera?

Exactly what I was looking for

I am not knowledgeable at all on camera tech but I needed to replace one that came with my camera and this one is perfect. It so far holds over 1,000 photos and videos on it.

Good card, doesn’t work with rebel xsi

It looks like a nice card, but if you have a rebel canon, don’t bother, both of my rebels refused to format the card

Good card

I had to return this because it was too much memory for the slide viewer I bought. It fit in the viewer but I got an error message. I am returning it. I bought a 128MB from the same company. It works great.

GIGASTONE - Performance, compatibilité, fiabilité - dans un seul mot QUALITÉ à un bon prix

J'ai acheté cette carte SDXC pour un appareil Kodak PIXPRO. Aucun problème, la carte a été reconnue et formatée, j'ai pris quelques photos et de petits vidéos, aucune hésitation ou retard dans l'enregistrement ou visionnement. Par curiosité j'ai essayé cette carte sur un appareil Nikon qui appartient à ma fille, la même performance. J'avais aussi un Canon PowerShot SX20 vieux de 17 ans (2009) avec une petite carte SD 8GB, j'ai acheté deux GIGASTONE SD 32 GB et je suis heureux. sont parfaitement compatibles, j'ai ressuscité mon appareil, j'ai lui donné une deuxième vie. Et des prix imbattables par rapport à la qualité, autant pour la carte SDXC 256 GB que pour les deux cartes SD 32GB. Essayez cette marque! De plus en cas de problème les cartes sont retournables sur Amazon!
