Review on Reliable and High Performance Transcend 256GB SDXC/SDHC 300S Memory Card - TS256GSDC300S by Brandon Addison

Transcend 300S 512GB SDXC card writes at 50MB/s and reads at 80MB/s in the built-in CDM reader in my HP Elitebook (see attached image) . The price of the card is acceptable. I have no problem recording 100Mbps 4K on my Sony RX100 VII. Overall, this is a very solid SD card option, with performance on par with comparable but more expensive cards from some of the more well-known brands.
