Review on Silicon Power 64GB MicroSDXC UHS-1 Memory Card (Adapter Excluded) - Ideal for Dash Cam and Raspberry Pi Memory Card Compatibility by Brockington Zuniga

The product comes with an SD card adapter. I compared it to several cards using the test program on my Android phone: <table><tr><th>Card</th><th>Read (Mbps)</th><th>Write ( Mbps ) s)</th></tr><td><td>Silicon Power 32Gb</td><td>55.1</td><td>18.6</td></tr><td><td > Scandisk Ultra UHS- 1 16GB</td><td>30.3</td><td>8.07</td></tr><td><td>Samsung Evo 64GB UHS-1</td><td >33</td> <td>16</td></tr></table>I think Sandisk is buggy because it's the only card that mysteriously shuts down.
