I bought a new underwater camera. So my 32 GB Adata went to the camera and this Sandisk went to my Galaxy Note 10.1.  On our family vacation I took the newly purchased camera and the 32 gb Adata.  Long story short:  A lot the photos and videos taken in Cancun are gone.  Photos and video from top of a Mayan ruin (pyramid), snorkeling, family photos are all corrupted and gone.  At first, I thought it was the camera until I placed the Sandisk in and experimented with it.  This Sandisk was flawless!  I will be staying away from lesser known brands and staying with Sandisk going forward.
