• SD Card
USB Low & Full speed (@3.3V) Transmit traffic AF% less than 10% (max 50TB over
lifespan) per port or use only High Speed or Super Speed USB devicesUSB Receive traffic
is not affected. Connecting Low or Full Speed devices through a USB2 High Speed (or
greater) hub mitigates the issue.
•SD Card (operating at 3.3V) AF% less than 10%. UHS-1 cards operating at 1.8V are not
affected.
Usage of SD cards operating at 3.3V should be minimized and usage should be limited to
UHS-I type SD cards operating at 1.8V. Inserting the SD card, and leaving it in the system,
as extended storage, reduces the life of the interface. Occasional usage of SD card,
inserting the card
–transferring data to or from the SD card-then removing the SD card, is
not a concern. Customers have the option to enable a default D3 device setting to extend
the life of the SD card interface, if supported by the OS.
