Samsung EVO Plus 256GB for $29 is great price, as cheap as the last historical low posted 3 months ago
Link to Dahua MicroSD Class 10 U3
Very cheap per gigabyte. DAHUA mostly makes CCTV's and so this Micro SD card is likely a rebadge of some other OEM, likely Sandisk or some other lower-tier manufacturer.
Dahua is 100mb read 80mb write…. Better spend 9 dollars more for Samsung 160mb read
