I got a new USB3 UHS-II compliant card reader as all of the card measurements i was taking with my older Toshiba Portege's built-in PCI SD card reader ("Ricoh PCIe SDXC/MMC Host Controller") seemed to top out around 40MB/sec write and 60 MB/sec read
new reader:
https://www.amazon.com/gp/product/B012PSAEDC
I still have some of the cards tested above, will rerun. where you see "Lexar SR2" in test note, thats the reader im using.
I have a slew of these Portege R83x/R93x laptops for home and work use (like my audio gear, im a brand loyalist and have been using toshiba for 2 decades). cards at home that were running 40/60 do 50/70 on what i believe is the same PCI-e controller and driver, will investigate
ive also seen differences of 10% on the Lexar SR2 depending on the USB3 controller and driver to which i connect it
Point being, i suppose, is there are vast differences in how different hardware and software installations handle the same card (which is the point of this thread, i suppose)
