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?

Dear customer, We checked your camera specifications, and confirmed that this camera model supports memory expansion up to 256GB Thank you, Gigastone

動作保証外ですが、Canon EOS R50で問題なく使用できています。主に野球観戦に使用してますが、写真も動画もかなり保存できるので、データ整理の手間が省けてかなりたすかっています。

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!
