Supported SD cards
SlingStudio supports UHS-I or UHS-II SD cards with at least UHS Speed Class 3 (U3) or above. The size (capacity) of the SD card can be whatever best suits your needs, as long as the speed class criteria are met.
The following SD cards have been tested with SlingStudio:
SanDisk Extreme Plus
SanDisk Extreme Pro
ProGrade Digital SDXC UHS-II
We will continue to update this list as more cards are tested.
How can I test the write speed of my SD card?
The SlingStudio Console app offers an easy way to confirm whether your SD card is capable of write speeds that are fast enough for your project's needs: It's in the Console app's PROJECT SETTINGS dialog box (you see PROJECT SETTINGS either when you create a new project, or if you tap the Settings icon in the upper-left corner of the Console app, then tap Project Settings). Under SAVE PROJECT TO, tap the Test Write Speed link to test your SD card's write speed.
Generally, for bit rates greater than 10 Mbps or for multiple streams, a USB 3.0/SSD drive might be a better choice.
