Scheduled to get CitiDisk HD to test for a week.
 

a local vendor has offered to provide me with a citidisk to use for a week with my HVX200. Seems there has been difficulty in dealing with recording in the mxf format, and files are written with some proprietary "workaround". But, have been told that manufacturer (Shining?) wanted to find a few HVX owners to test out the drive and report back. That should be within a couple of weeks. Looking forward to it. I welcome suggestions for tests.

ROFL..
These little drives are often barely able to handle the HDV 1080 stream of 25 Mbps. That HDSDI port on our XLH1s export footage that is roughly 1.485 Gbps!
If the drive were even close to fast enough, it'd be great! -except at 100GB it wouldnt hold any decent amount of footage! You'd need some sort of compression module to make the drive able to hold any reasonable amount of footage.

The smallest HD-SDI Direct-to-Disk recorders I've seen are rackmount setups about the size of most home PC towers out there (but layed flat) and have multiple high speed hard drives that collectively hold 1-2 TERRAbytes. And even in Cineform compressed mode (180-250 Mbps) still only hold ~19hours of footage (depending on compression rate and hard drive configuration).

But I share your assessment- an UNCOMPRESSED 10-bit 1920x1080 capable HD-SDI recorder of decent capacity that you could mount to a camera would be darn cool wouldnt it?
