This NVMe SD card is literally too hot to handle

When we say a gadget has “blazing-fast speeds,” we don’t mean it literally. But when AnandTech benched one of the first NVMe-based SD card reference designs, it found the tiny plastic-covered rectangle hitting skin-searing temperatures of 96 degrees Celsius (roughly 205 degrees F).

Last year, we wrote how this next wave of SD cards — SD Express — might quadruple their theoretical speed to nearly four gigabytes per second, by using the PCI-Express and NVMe interfaces more commonly found in the SSD in your computer or next-gen game console.

Theoretical speeds are theoretical, but this is still fast

We haven’t quite hit those speeds yet, anyhow: the specific card AnandTech tested topped out at around 900MB/s writes and 400MB/s reads in...
