Not really much to say here other than it's a good memory card. It is my current largest capacity memory card for my camera. And I use it pretty much every day. Be sure to double check that your camera or device is compatible with the specifications of this card it is a high-end device. And some older devices may not correctly recognize it. I have not encountered that myself but that doesn't mean that someone out there won't.

This SD card can be used easily for video or audio recording and is compatible with most or if not every device that takes SD cards. It is small and compact and is great for audio, video, or any kind of media project with fast transfer speeds.

We took this on vacation and loaded it up with hundreds of photos and videos and there is still room for more. Excellent quality and I like the larger size so I didn't have to worry about running out of space while I was taking photos, especially underwater photos. Easy to use in a card reader that I could connect with my phone to view photos. Great quality and great value. Highly reliable.

I'm using these for music storage to play in my Audi which has 2 SD card slots. Audi recommends full SD cards instead of micro SD cards with adapters. I've had good experiences with SanDisk cards in the past so this was my first choice. No compatibility errors and good price. I couldn't ask for more.

si compran de otro país la caja blister es distinto que en Sudamérica eso hace dudar, aunque es original. vino un poco ultrajada la caja pero ha llegado rápido a mi país argentina.

I upgraded my 64 GB Sandisk to 256 for video work. I have been buying Sandisk since the 90s and never had an issue. I only upgraded to get more space. My workhorse 64 GB set (My Nikon runs two of them) was getting full every weekend, so it was time to upgrade. Great card. I think I only formatted a few times just to get a clean start on them. They have been thru 2 different cameras. I expect these 256's will be the same.

The item is great good quality product and speed. I’m not happy with the delivery guy though he left it out side of my apartment outside the main door. He should of left them inside the double door.
