I've played with it after switching the cable from the front to the PC's back panel. The same file of 1.2GB could be copied once in just 1 min, but then again it takes over 3 mins! What's interesting, during those slower operations, the red lamp on the DR60 does not come up - at least not from the very beginning. During the quickest (1 minute) copy, it lights all the time.
Strange. And frustrating. |

Thanks Chris! My further observations:
- I had to switch auto defragmentation off; this alone took me from my best so far 1 min/1 GB transfer down to some 45sec/1 GB - regarding the slowest transfers, here comes the most interesting part: it's the RAID 0 that the copy takes ages to and from the DR60! To a standard IDE drive, I can copy to the DR60 and back at 45 secs/1GB. Now, go figure. All my diagnostic tools show everything is in perfect order with my SATA RAID (s) - 300 MB/sec transfers! I'm suspecting some conflict between firewire and SATA.... |
Guys, I think I owe you explanation that my alarm was false. Somehow, my RAID 0 was misconfigured. All in all, the HVR-DR60 does not have the transfer limit of 50% real-time capture speed, like its predecessor the DSR-DU1; it performs like a regular (not very fast) 1.8" IDE drive. A file weighing around 1 GB can be copied in some 45 secs; 12 GB will thus take some 8 minutes vs 1 hour of capturing - huge time savings!

Thanks Chris for your cooperation. I'd like to add that setting the performance policy for DR60 in Device Manager (Windows) speeds up the transfers still further!
I have another question: apart from the VIDEO and USER partitions, there is some 32 MB free (unpartitioned) space at the end of the drive; while it's not much space, every little counts (and it's not very elegant). Do you think it's possible to re-partition the drive from within Windows and extend the VIDEO partition, deleting both the USER partition and that slack at the end, without disturbing the functionality of the unit? |
