I recently purchased a Chromebook (ARM). It has an SD card reader and a USB 3.0 port, but I have neither an SD card nor a USB 3.0 flash drive!
If I were to boot from Ubuntu on one of those two devices, which would give me better performance? Which should I purchase?
To be clear, the devices I'm choosing from are:
I would like to answer about transfer rate.
Transfer rate for:
SD Card
USB 3.0
There are currently three speed modes defined by the latest USB 3.0 specification. They are SuperSpeed, Hi-Speed and Full-Speed.
The new SuperSpeed mode has a transfer rate of 4.8Gbps (600 MB/sec). While the specification retains Hi-Speed and Full-Speed USB mode, commonly known as USB 2.0 and 1.1 respectively, the slower modes still operate at 480Mbps (60 MB/sec) and 12Mbps (1.5 MB/sec) respectively and are kept to maintain backward compatibility. Check out this page for a comparison between USB 3.0 and other competing interfaces such as eSATA, FireWire 800 and Thunderbolt.
I suggest you to use flash drive to boot.
