## Description

Transcend 512GB microSDXC/SDHC 300S Memory Card TS512GUSD300S-AE

Review: Realiable - Good sd card
Review: 512GB Card | Ordered for Insta360 X3 - The desertcart packing was good, but the actual packet was bit tampered. I received 1 512GB memory card and 1 adapter. Transcend USD300S A1 512GB UHS-I U3 with V30 Micro SD Memory Card up to 100/85 MB/s microSDXC I with Adapter (TS512GUSD300S-A) When I connected this memory card to my laptop I only got 470GB available memory out of the 512GB. Expected a bit more available memory. 42GB for cache and other things seems too much. I have ordered it to use it in my Insta360 X3. When placed for the 1st time, it shows 13 hours + recording time for 360° video. Sufficient to cover any event. Will try to update the review once I have done some work using this card. Will keep you posted.

### ⭐⭐⭐⭐⭐ Great value SD Card
*by J***N on 20 July 2023*

Came in a funky non retail packaging which I had never seen before. Got it for a great price on Prime Day. Speed is UHS class 3. Transferred around 90GB of stuff onto it from inside my phone as a test and it went well so this should be a geniune SD card.
