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

Transcend 300S 256GB SDXC card writes at 50MB/s and reads at 80MB/s in the built in reader in my HP Elitebook according to the CDM (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.
