  1. That's great Eric that you have got it up and running. Of all the people I have heard TALKING about it you are the first person, I have seen, with an actual usage report. I've been waiting for this.

     

    Despite your confident dismissal about the SSD degrading over time/usage issue, it is an issue. There are tools out there to defrag them to keep them running in an optimal manner but you have to be on top of this. I don't believe you can do this in the unit but have to do the defrag on your PC/Mac. Probably won't matter in your case but if someone was using this in production as a recorder to capture production footage and frame are dropped, it is an issue. RAW 422 10 bit material does push the limits of a single SSD drive. The Convergent Design people have been wrestling with this issue in developing their new SSD based recorder and have developed defrag routines to keep the drives running at full strength.

     

    Optimal performance is key for SSDs to capture flawlessly. Down the road it could become an issue.

     

    Did you make your cables Eric?

     

    A minor clarification; Andrew I think you mean “Trim the SSD” which is something completely different than a Defrag. Typically you don't want to defrag a SSD as such operation will shorten its lifespan, cost unnecessary write cycles, and doesn't add any value to its performance due to how a SSD actually works at low level. All modern O/S will disable the defrag option for a SSD so it’s the Trim* feature you want and need. The Trim command basically tells the drive that a memory block is available and can be zero'd out while the drive is still being used by the system. This way the write performance will be on top all the time. A drive without Trim support will after some time usually have a huge write performance hit, usually in the range of 50% to 60% less write performance based on my own experience, but only during the second and forward write cycles of that specific block. Of course Trim must be present in both the actual drive and the operating system or by using a 3rd party tool. For instance Intel has a tool for their Trim supported drives if you are running XP or Vista as those systems don't support Trim natively.

    This post was written on a machine with a SSD and Trim support :-)

  2. Hi,

     

    Currently looking at some 2nd hand Flyers rigs and I am trying to determine if they are the LE variant or.

    Is there any simple way to distinguish that release from the older ones, if I understand it correct LE is the third generation of the Flyer (please correct me if I have misunderstood it .-))

     

    The one I have on my radar right now was bought in 2007 so in case someone can confirm the LE was available at that time I will continue to investigate else I will drop it from my list.

     

    Thanks a bunch,

    Thomas
