These SD cards work wonderfully in my Sony camera's, I've yet to have a single failure or corrupt drive. Over the years, they've proven to be extremely fast and reliable. Make sure you're buying genuine, but, this seller is selling the real deal. You'll enjoy these over the cheaper options for years to come. ... show more

Lightning ship. Professional packaging. Great communication. I am a previous Sandisk user, therefore I am aware as to how good their product is. This was purchased for a 2025 C8 Corvette PDR system = Performance Data Recorder. I am confident that even though I have not used it as of yet, but I am confident that it will be perfect. Will recommend highly. As far as for Longevity including usage!! Time will tell and I will update if any changes occur. A JOB WELL ORCHESTRATED FROM START TO FINISH. Just perfect! Thank you. Anthony.

  • Quality
Capacity: 128GB Style: Memory Card Only
San Disk makes great memory cards. This one holds 128 gb, which is great for the photo expeditions I've been taking recently. I have re-formatted this disk many times after completing a photo shoot, with no degradation in image quality.

  • Solid memory card
Capacity: 64GB Style: Memory Card Only
It’s an SD card. Same as most others with slightly less capacity than rated, but again that is typical of most memory. Fits my Nikon DSLR’s and works well with them. Solid, quality card for cameras. Has plenty of capacity for a day of shooting hours of Raw files.
