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 analyses reviews to verify trustworthiness.
Diversamente a quanto specificato sulla confezione e sulla descrizione AMAZON.it, la velocità di lettura e scrittura di queste Micro SD non è 90MB/s ma 18-20MB/s in scrittura e 38-40MB/s in lettura. Come sempre, le uniche SD che rispettano le velocità dichiarate sono solo le SanDisk Extreme Pro. Le sconsiglio vivamente a chi deve usarle per trasferimenti di dati veloci. Usate con adattatore da Lightning iDragon funzionano bene e la registrazione di video da iPhone 7 direttamente su micro sd esterna regge anche il formato 4K, contrariamente a quanto ci si potrebbe aspettare. Almeno costano, relativamente, poco.
I am not sure if the set I got were subjected to an anomalous static damage , or perhaps they were simply a product of bad manufacturing, I randomly got corrupted file messages, tried to use it as a boot device in my Pine64 and got errors booting up. I put both of them in the trash can and replaced them with ScanDisks, and all my errors disappeared.
One of the memory cards stopped working after 2 months which was found for my dashcam. I thought that was the problem of the dashcam and switched to another memory card and turned out one of them was bad. Not impressed at all for this price.
BURNED MY HAND!!! I put the cards in my wifi cameras and the others seem to be doing ok however one of them was not working so I went in to check and to pull the card out of the camera it BURNED my Fingers. I would just go ahead and say its not worth BURNING YOU HOUSE DOWN.
