  • Died after 2 years, twice! (Bought two)

    Died after 2 years, twice! (Bought two 128GB, about 6 months apart.) One reached the end of it's write cycles (files still readable, but read-only) The other was corrupt and unretrievable. Samsung really messed up this generation of card. It looks like I'm not alone.

    I purchased this for my 4k dashcam. When I started looking for this sd card, I found a lot of the reviews were warning of fake cards, but the one I got from BestBuy looks totally legit and is working well in my dashcam. Thanks BestBuyfor having a sale price :)

  • stopped working suddenly.

    I bought this a number of months ago, I didn't use it immediately. I started using it in my phone... hadn't used up all the memory but I used it for all my music, videos, apps and photos. I hadn't even used even half the memory available. No viruses or anything on my phone, opened my calendar app (one of two apps in use at the time, the other being phone)... and all the sudden it just seemed to die... first it says the netflix app experienced a problem and needed to close... and then chrome... and then calculator... next thing I know... all my apps are grayed out and none of my non-cloud photos are there... including all irreplaceable photos of my recently deceased dog... It isn't recognized by any computers and all the information is just gone... Up until it died... it worked as expected. No app lag. But too expensive considering how suddenly... and randomly it died. Incredibly disappointed considering the hefty pricetag.
