A single native (non-USB) SATA 3.0 port on the ODROID-M1 is provided for use with a 2.5inch HDD or SSD NAND Memory storage device. This SATA interface delivers near 500MB/s of sequential access. The SATA mount kit contains a SATA Data cable, a SATA Power cable, and a mount plate with some support screws.
The SATA power port doesn’t have a 12Volt power rail, so a separated external 12Volt SATA power supply is required to use a 3.5inch HDD.
SATA cannot be used together with M1 metal case.
