Decent price and quality
I bought this card for my GoPro 12 action camera. Works fine. It provides 8.4 hours of highest quality video recording on my camera. It is also very useful that this micro SD card comes with an adapter, so that it is possible to use it on my DSLR Canon camera and laptop.
Colin Hudson – 28/04/2025
Affordable Storage
For the price, itâs excellent. 512gb. Stored all video shot at 4k 60fps and 120fps perfectly and is still working good.
eHackster – 28/04/2025
Fast and reliable
This 128GB microSD card from SanDisk is fast and reliable. It’s perfect for video cameras and dash cams that record in UHD. It has performed flawlessly without any issues so far. It comes with an SD card adapter for use in card readers.

Tapo
I bought this to use in one of my Tapo security cameras and it works perfectly. Very easy to install and format. I have had no data corruption with this micrsd. It is a good price but there are some just as good but a little cheaper such as gigastone. Picture quality is excellent and durable. Can be viewed as if watching it live.

GREAT for storing a lot of movies on your phone
What can I say about this? It just works. It is fast and offers a lot of storage. This is perfect for storing a lot of movies on a phone.

Great Chip, Condition???
I believe this these were listed as “Used-Like New”.Perhaps I got spoiled but these (2ea) arrived with more then original packaging issues. The seal broken and the chips obviously have been used. The chips just needed formatting.I knocked the rating 1 star because of the condition. IMO should have been “Used-Good”.

Mittlerweile muss man echt aufpassen, dass man keine gefÃ¤lschten Speicherkarten kauft. Ich hatte vor kurzem eine Karte im Internet bestellt (nicht hier), die bereits nach ca. 60GB Lesefehler im Test zeigte obwohl ca 970GB Gesamtspeicher angezeigt wurden. Die Verpackung sah genau so aus wie das Original, nur die Karte war in dem kleinen Kunststoffblister nicht eingeschweiÃt gewesen. In der Praxis wÃ¼rde dies am Anfang hÃ¶chstwahrscheinlich gar nicht auffallen, aber spÃ¤testens wenn die ersten Urlaubsfotos vom Smartphone nicht mehr lesbar sind kommt dann das groÃe bÃ¶se Erwachen. Ich kann jedem nur raten generell alle neu erworbenen Speicherkarten vor ihrem Einsatz auf ihre GrÃ¶Ãe zu testen. Ein gutes Programm hierfÃ¼r ist z.B. h2testw (gibts bei heise.de). Zeigt das Programm Lesefehler an, ist die Karte hÃ¶chstwahrscheinlich eine FÃ¤lschung und man sollte von seinem Widerrufsrecht Gebrauch machen. Im LadengeschÃ¤ft mÃ¼sste man auf die gesetzliche GewÃ¤hrleistung bestehen, da der Hersteller bei FÃ¤lschungen verstÃ¤ndlicher Weise keine Garantie gibt.Die gelieferte Karte hier hat den Test allerdings bestanden und ist kein Fake (siehe Screenshot). Die Schreib- und Lesegeschwindigkeit ist wahrscheinlich in diesem Fall durch meinen Kartenleser limitiert.

Goede SD kaart van Sandisk voor een mooie prijs. Ik heb al meer geheugen kaarten van Sandisk die na al die jaren nog uitstekend werken. Deze heb ik aangeschaft voor in een 3D printer, ter vervanging van de standaard kaart die bij de printer zat.
