Review on 💾 128GB Transcend MicroSDXC/SDHC 300S Memory Card - TS128GUSD300S by Nap Olivas

Very good value added to 2 DVRs. The speed should be good, the temperature range is good. We'll see how many cycles it takes, but it's rated for 10,000 insert/delete cycles. I will let you know if/when they die. Flash memory TLC NAND.
