    Cumplen con el objetivo, hasta el momento ninguna se me ha dañado. Tengo 2 meses con ellas, las he usado bastante y todas han funcionado perfecto. Me encantó que vienen varias en un solo paquete, si les vas a dar uso muy seguido, funcionan súper porque puedes organizar tu material por tarjeta. ¡Recomendadas!

    I grabbed this sD card because of its wider compatibility with some older electronics and it’s cheap price. Some older digicams can have strange compatibility issues when using either higher capacity cards or fast speed cards, but this one just works. This one pairs perfectly with my Fujifilm z20fd and is more than enough storage for this camera. If you need a spare sD card or a reliable sD card, grab this one!

    The SanDisk 128GB Ultra SDXC UHS-I Memory Card has proven to be a reliable and fast option for expanding my device’s storage capacity. With its impressive read speed of up to 120MB/s, this card has been a valuable addition to my photography and video recording needs.

    The storage capacity of 128GB is ample for storing a significant amount of photos, videos, and other files. I’ve used this memory card in my digital camera, and it has easily accommodated high-resolution images and Full HD video recordings without running out of space.

    The card’s UHS-I technology and Class 10 rating are evident in its performance. I’ve experienced minimal lag when capturing continuous shots in burst mode, and the video recording has been smooth and without interruptions.

    Additionally, the card’s compatibility with Full HD recording is a big plus for those who use it for video work. The ability to capture high-quality footage without concerns about storage limitations is a major advantage.

    One minor drawback is that, while the card’s read speed is impressive, the write speed might not be as fast, especially for larger files. This is something to keep in mind if you frequently transfer large amounts of data from the card to another device.

    In terms of durability, the SanDisk brand has a reputation for producing reliable memory cards, and this one is no exception. It has held up well to regular use, and I haven’t encountered any issues so far.

    Overall, the SanDisk 128GB Ultra SDXC UHS-I Memory Card is a solid choice for anyone seeking a fast and reliable storage solution. Its impressive read speed, ample storage capacity, and compatibility with Full HD recording make it suitable for both photography and video enthusiasts. While the write speed could be improved, the card’s overall performance and durability earn it a solid four-star rating.

    Me ha funcionado bien. La utilizo en una grabadora de audio y, hasta el momento, no me ha fallado.

    Die SanDisk Ultra 256GB SDXC Speicherkarte hat mich in jeder Hinsicht beeindruckt. Ich vertraue bei Speicherkarten ausschließlich auf SanDisk und wurde auch diesmal nicht enttäuscht.

    Die Kapazität von 256GB ist mehr als ausreichend, um eine große Menge Fotos, Videos und andere Dateien zu speichern. Die Geschwindigkeit der Karte ist hervorragend, mit einer Übertragungsrate von bis zu 120 MB/s. Das ist besonders wichtig, wenn es um das Speichern von hochauflösenden Bildern und Videos geht.

    Die Klasse 10 und UHS-I-Klassifizierung garantieren eine schnelle Datenübertragung und Aufnahme von Inhalten. Ich habe die Karte sowohl in meiner Kamera als auch in meinem Laptop verwendet und sie hat jedes Mal einwandfrei funktioniert.

    Die Zuverlässigkeit von SanDisk ist bekannt, und diese Speicherkarte ist keine Ausnahme. Sie bietet die gewohnte Qualität und Langlebigkeit, auf die ich mich immer verlassen kann.

    Ein weiterer Pluspunkt ist die Kompatibilität dieser Karte mit einer Vielzahl von Geräten, sei es Kameras, Laptops oder andere digitale Geräte.

    Insgesamt kann ich die SanDisk Ultra 256GB SDXC Speicherkarte ohne Vorbehalte empfehlen. Wenn es um Speicherkarten geht, ist SanDisk immer meine erste Wahl, und diese Karte hat meine Erwartungen mehr als erfüllt.

    What can you say about San Disc? Just the best. Lasts a long time and doesn’t stop working like cheaper brands

  7. Kidus Tsige

    I purchased two new camera bodies this year and these cards make it easier to use the new cameras. Now all of my cameras use the same type of card.

  8. Susana Brijandez

    Funcionan excelente.

  9. John C

    I have a super inexpensive camcorder that this works great with.
    Very pleased.

  10. Stylus

    I like to store my old CD’S on cards or sticks good sound and these hold a lot of music or pictures I like the SanDisc brand I have had good luck with them.

  11. Jeff Hoogmoed

    Great cards wish they had a card holder to use while not in use.


    Easy to use and great storage capacity

    Questa memoria essendo da 32Gb richiede una certa corrente ( quindi mA ). Altre memorie simili funzionano senza problemi anche su di un HUB, ma questa vuole la porta USB tutta per se, Soprattutto perché ha bisogno di un adattatore (che anch’esso vuole un po’ di corrente), sommati due consumi troviamo una richiesta alla presa USB di un amperaggio superiore (che non ho avuto tempo di misurare). Ottima memoria, rapida nella lettura e scrittura. Consigliabile!
