According to the December 2010 version of the Flash XDR user manual:
Flash XDR is a revolutionary solid-state HD/SD recorder/player that uniquely utilizes the very high quality Sony XDCAM 4:2:2 CODEC to write native Quicktime, MXF (video/audio/time-code), or MPG files onto affordable Compact Flash media. Flash XDR breaks ground in terms of weight, power, size, ruggedness and ease of use. We are confident you will agree that the video quality is indistinguishable from uncompressed (at 100+ Mbps Long-GOP or 180+ Mbps I-Frame modes).
Has 4 compact flash (CF) card slots and ports for XLR cables as well as various other connection ports as shown in the photos. Could be useful for both video and audio projects.
I used this piece of equipment for recording HD video with my Canon XL-H1s and for doing video transfers from mini DV tapes to CF cards. I got this Flash XDR in 2014 and rarely used it since then, and it has mostly been in storage for 7 years. However, I did use it to transfer a lot of mini DV footage to CF cards a few years ago.
NOTE: The highest quality bit rate I could achieve with this unit is 180 mbps. I was never able to get the date and time settings to stick after I set them. I'm not sure if this is a quirk of the Flash XDR or this particular unit. As far as I can tell, unless you correct the date and time each time you turn on the unit, all videos will say they were recorded on 12/31/1999. These may or may not be issues for you, and somebody more technically savvy than me may be able to address them.
Also, as is normal for the Flash XDR, it does not come with an external power source. It has a cord that lets you power it from an electrical outlet, but you'll need to get a battery or find some other sufficient means to power the unit.
