These are the endurance models more designed for video monitoring cameras (dash cams, surveillance & security cams, CCTV, body cams, etc). Not the best for value/GB for normal storage tasks, but might be of interests for some considering dashcam deals were popular lately.
Very good pricing (local pricing check) if you are already buying something from Amazon US via your AU prime membership (or alternatively, buy two to get free shipping). The Samsung PRO Endurance 64GB cards are also rated for more than double of the competing SanDisks. A comparison review here: https://carcamcentral.com/guide/recommended-sd-cards-avoid-s…
Make sure the seller that's selected is Amazon US (and don't forget 5% CashRewards, or 6% ShopBack AU).
