Review on 💾 512GB Micro SD Card Memory Card with Adapter - High-Speed 100MB/s, Class 10, U1, Full HD Support, A1, 512GB Ultra microSDXC UHS-I Memory Card by Kyle Whitehead

Good for those of you who have never used cards of this size or type before. When you open it with it, it only shows 119-120GB free space. This is because manufacturers specify 1000MB per GB while actual file systems specify 1024GB per GB and also part of the available space is allocated to FAT (File Allocation Table) so the computer/phone/tablet can basically know where on the map the information is actually stored. Type: It's a U3 card, so very fast, but it depends on a few things, mainly what kind of reader you're using. If it's not a USB 3.0 or 3.1 compatible reader, you won't get the speeds listed because you're limited by the hardware you're using. If you use this card in a USB 3.0 or 3.1 compatible reader and port, you will find that it will match the listed speeds. Conclusion: This card meets the advertised specs and works very well (the card only lasted about 1 month with no reported durability). While this card isn't one of the well-known brands in this space, it's as fast as my Samsung u3 and costs less than 1/3 the price. If I need another one I will definitely buy another one of these.
