  Thunder bolt Daisy chain. – One drive copies files more slowly than the other three.

  Posted by Christopher Tegg on January 4, 2013 at 12:05 am

  Hi.

  I have a wee issue occuring where I have been trying to copy a relatively small folder of files to one of my pegasus R12 drives, in a daisy chain of 4.

  It says 2 hours for 27 gb. I tried the same on the other 3. – Only 11 minutes.

  The drive is not full . has a spare 1.5 tbs.

  Any thoughts?

  Thanks all.

  What’s a “Pegasus R12”? Possibly Pegasus R6 12TB? I thought I missed the R12 announcement – but then Google turns up nothing on it, so it must be R6?

  I have no clue as far as the issue but will be very curious what’s causing it. Do arrays benchmark OK when tested individually?

  Are these four identical arrays? Are you copying between them?

  Regardless, 27GB in 11 minutes translates to 41MB/s if I am not mistaken, which is horrendously slow for R6. Something’s not right here. Bad cable? Bad TB chip in your iMac or MBP? Could you test the arrays individually and post the results (MB/s) here?

  Try altering its position within the daisy chain, perhaps as drive #1 closest to the computer.

  While FireWire is a robust standard that should allow you to daisy chain that many drives, there can sometimes be some reliability issues or conflicts with certain drive combos on the same daisy chain.

  *Edit* I totally missed that you meant Thunderbolt… but I would still try the same process.

  Cheers for that.

  Would this change the pathways that my premiere pro reads. I don’t want to have to relink a bunch of media.

  Thanks

  In OSX you should be fine, I think it recognizes drives based on info like name and serial number. On Windows, it’s a little more liberal so it may grab the first available drive letter, but you can assign them manually in one of the disk admin panels.
