Hi Walter, whilst what you are saying is maybe correct, things are a little different with the Mac OS and SSD’s. As far as I can understand, the Mac OS, particularly Yosemite, disables the trim function on third party SSD’s and this leads to premature failure. Apple certified SSD’s and fusion drives are ok but in Michael’s situation where he might buy a “Lacie” external SSD for instance, he would have to be sure that it is Mac qualified. That may be a sticking point.

I checked out the Lacie 4tb thunderbolt and the specs suggest speeds around those you are experiencing. However, if I’m correct, the Lacie has only one disk inside and although the thunderbolt interface runs at a massive 20GB/s you are still stuck with the maximum that a single disk can read and write. Thunderbolt has ample capacity to to handle multiple disk RAID read and writes simultaniously so this is where the increased speed comes from. A single disk enclosure wont show a dramatic speed increase because the disk is working at it’s max, where a 2 disk Raid would pump out much more and that would be very easily handled by the Thunderbolt interface. The “off the scale” speeds shown in the YouTube clip are achieved by striping multiple disks, each only as fast as your single disk but multiplied by the number of disks in the RAID configuration. For the amount of angles you want I would suggest a 4 disk RAID 0.

Though journaling is for boot volumes it doesn’t have a huge impact, well not 30-40% slower. What are the actual speeds shown by speed test.

[Roger Poole]

Slow thunderbolt. Did you format the drive to Mac extended, not journaled?

Hi Michael, if you need so many angles, as already suggested, you need raid. There a two things to consider, the speed of the hard disk itself and the amount of data the interface can carry. I would suggest a 4 way striped thunderbolt raid. You would never saturate the thunderbolt interface and get some astonishing speeds which would be up to streaming multiple angles. Try downloading the Black magic speed test utility and test your media drives, then watch this….

Edit: I just tested my G SpeedQ Raid 5 and get just over 200 MB/s read and write via esata. Thunderbolt would be off the scale.

Mike, before you go. Looking at picture 3 it looks like the stereo clips are ok but the mono clips are where the problem is. Basic I know, but have you tried highlighting one of the problem clips in the timeline and choosing “reconnect media” from there.

[Roger Poole]

I completely agree with Michael’s caution. Given the situation I wouldn’t mess around with the media drives because of the risk of causing problems with the fallback position of continuing the edit on the G5. I was in a similar situation a couple of years ago when asked to finish a project created by another editor who was working on a G5. I received all the raw media files, the project files and nothing else. Of course the whole project had to be recreated from scratch on a “New name” media drive, but it all worked out fine. Mike’s situation is different because he has the identical media drives which he had on the G5, so its a straight re-link, which might be where the problem is.

Hi Mike, if you are now running FCP 6.0.6 you’ll be right. Christopher seems to have come up with an answer to the waveforms problem. Get to work and give FCP a thrashing. See how it works out for you.

How did we get things done before the internet. :o)

[Roger Poole]

Well..You learn something every day! Nice catch Christopher.

[Roger Poole]

Hi Mike, things are getting confused as you have two live threads running. I see in the other thread that you have successfully installed FCP6 on the new disk, well done. The main issue relating to this thread, do you have your audio waveforms back?
