Excellent product, have used this in the woods, started the down load placed the unit in my shirt pocket and continue taking pictures on my other card; after a bit, erase the card and ready for more pictures. The battery life is much better than expected; this feature allows the extensive use of this Hyperdrive making it a welcome piece of equipment to my pack.

I got this to phase out my PD70X (same company) At full speed (20 MB/s avg with Sandisk IV UDMA) this is way faster but it also uses up the battery faster. At full speed don't expect more than 32-36GB on a single charge. If you slow it down some you might get the 120GB max but that would be pointless. To change the battery you must have a screwdriver handy. THIS IS REALLY STUPID. Honestly I would keep using the PD70X if it were not for the fact that the CF slot is shallow and pins get bent easily. The color space CF slot is very nice. It's also nice to format the drive without a separate SD card. The unit also has built in card utilities which could be a lifesaver in the field. Overall I like it very much. here my main complaints:too expensive (paid [$]for case only)screwdriver battery compartmentno hardware power switchno visible cancel option in text modeslow processor (for image viewing, RAW D300 14bit images)no HDMI out (it should for post shoot, hotel viewing)
