To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness.
Formatted this on Win10 PC as exFAT- to 58gb. 4+gb got "lost" somehow. Data corrupted after a few weeks of use. Reformatted it and will see if it stays true or corrupts again. Would not use for holding/transferring any important data. If you use on camera, backup contents ASAP.
