PNY today announced its Elite 512GB microSD card, which is currently the highest capacity microSD card on the market. The card holds more than 100GB than the WD/Sandisk 400GB microSD card that was currently the highest capacity microSD card.
PNY promises a read speed of up to 90MB/s for the microSDXC Elite 512GB. It's unknown when the memory-card becomes available for sales, but PNY has already disclosed the card will sell at $349.99. Sandisk's 400GB microSD card currently sells at about $195, so there is a fairly large premium for the additional 112GB of the PNY Elite card.
The PNY Elite 512GB microSD card meets the requirements of the A1 (app performance) rating which means it should perform random reads and writes atleast at 1500 IOPS and 500 IOPs respectively. Sustained sequential writes need to be higher than 10MB/s seconds in order to be eligible for an A1 rating. That's much slower than the 400GB Sandisk Extreme, which is listed to be able to perform sequential reads at up to 100MB/s.
The PNY Elite 512GB is bundled with an SD card adapter for usage in devices that don't support the microSD format.
