PNY 64GB Elite-X Class 10 U3 V30 microSDXC Flash Memory Card, 3 Count (Pack of 1) - 100MB/s, Class 10, U3, V30, A1, 4K UHD, Full HD, UHS-I, Micro SD

Tengo que decir que me he vuelto muy fan de la marca PNY. Anteriormente, como amante de la tecnología, solo compraba productos de las marcas tradicionales, ya que pensaba que eran las únicas capaces de satisfacerme en cuanto a calidad, garantía y durabilidad.Sin embargo, desde hace un tiempo he probado distintos productos de PNY, y los resultados me han sorprendido gratamente. Es un placer corroborarlo con un producto como este.Principalmente compré la microSD por su excelente precio, en su versión de 128 GB, la cual está siendo utilizada para grabación continua con una cámara IP.Su capacidad de almacenamiento me permite grabar aproximadamente 15 días de video continuo en calidad HD, y la mitad del tiempo cuando aumento la calidad a 2K. No he tenido fallos de compatibilidad, como en otras ocasiones en las que la cámara, por alguna razón, interrumpe el video por unos segundos o simplemente deja de grabar debido a errores de escritura.Se incluye un adaptador SD para conectarlo a distintos dispositivos con este puerto, el cual utilicé para realizar las pruebas de lectura y escritura. Sin entrar en muchos detalles técnicos, obtuve muy buenos resultados: en lectura superó los 95 MB/s, y en escritura alcanzó hasta 88 MB/s, aproximadamente.Entiendo que el producto cuenta con una garantía de 5 años de vida útil, lo cual me parece excelente, ya que, si bien otras marcas ofrecen un tiempo similar, casi siempre encuentran alguna excusa para no hacerla efectiva. Pero ese no ha sido el caso con PNY.Me siento muy contento con este gran producto e invito a todos los que lean esta reseña a comprarlo sin dudarlo. Una vez tengan el producto en sus manos y lo hayan probado, me comprenderán...

They are used in our Wyze cameras. We can retain almost 5 days of video footage (continuous recording). They format quickly and easily.

Got these for general purpose use - one to add memory to an Android phone, and the other two for video storage in security cameras.They're plenty fast and work great for my purposes.

Works very well. Has a lot of space. Not much more to say besides that. would recommend!

Muy buen producto tiene buena capacidad de grabación

These sd cards are perfect. They come packaged nicely to protect them.Shipping was quick and they work great - they are 2K.

Purchased for a Samsung Tab S8. No complaints. The thing is fast enough to keep up with the device and of course provides the convenience of more storage.
