Elgato Game Capture 4K60 S+ allows for standalone recording without a PC to an SD Card.
The bit rate at which videos are recorded can be configured on the SD Card. Learn more about configuring standalone recordings here.
Not all SD Cards are made equal and offer differing read and write performance.
Since Elgato Game Capture 4K60 S+ only writes video files to the SD Card, the sustained write speed is important.
There are multiple ways to identify SD Cards and what their theoretical performance is.
Recommended SD card speed rating
Recommended is an SD Card featuring the speed rating of:
V30 (Video Class 30) or higher
UHS-3 (Ultra High Speed Class 3) or higher
If the SD Card features these markings, it can record reliability at 30 MB/s (Megabyte) or 240 Mb/s (Megabit).
Using higher speed SD cards
SD cards with higher speed ratings can be used and are supported.
Using an SD card faster than V30/UHS-3 will not increase the recording bit rate or quality.
The maximum recording bitrate of 4K60 S+ is 200Mbps (Megabit per second) or 25MB/s (Megabyte per second)
Identify SD card speed rating
SD cards come with markings on them to indicate speed ratings and may look similar to the image below. Some SD cards may feature only one, or both of the recommended ratings.
As long as one of the speed ratings is indicated on the SD card it can be used.
For more information on different SD Card speed classifications, see the table below.
