trying the camera with external SATA SSD

Just tried an external SATA 2,5" SSD from Intel.

Everything work perfectly and the SSD can be powered by the camera with a custom USB to SATA-power cable. Check the pinouts here: http://en.wikipedia.org/wiki/Serial_ATA

More information about those SSD can be found on : http://www.intel.com/design/flash/nand/mainstream/index.htm

and we measured about 18MB/sec write speed (limited by the ETRAX FS CPU), /dev/circbuf is ~19MB pseudo file in the camera:
