Rosbag Record Speed

I am trying to record a bag file on an odroid (ARMv7) Board that acquires 95 fps images from a camera but running rosbag record freezes the publishing topic. Also, whatever is recorded barely has 95fps data. So is it because the processor can't write at that speed? But if it is so why does it freeze after some time.

I also tried Tegra TK1 board which does not freeze but still the fps from rosbag on playing is around 10. Is it the same issue? Thanks

What resolution/bit depth are your images? Are they compressed? Are you compressing them on the fly using an image transport plugin? What kind of disk are you recording them to? What's the write speed on your disk?

Resolution: 2040x1086 Bayer BG Not Compressed, I am trying to record raw data. Odroids have 64 GB SSD so standard SSD Disk writing I guess would be write speed.
