How full are your drives? Rotating drives start melting down performance wise when they become 75% full. It is a result of increase file fragmentation and data throughput at the smaller "tracks" towards the center of the platters (data throughput is better at outer tracks).
If that is not it, do you have a way to monitor drive temperature? If your cooling is not sufficient, consumer rotating drives will definitely lose performance if they get too hot.
Hi, thanks for your help with this.
My work drives are not even 50% full. My boot drives on both machines have
about 60 GB free on a 500 GB drive - so a little more than 75% full - but
not that much more. I try to keep space on them as a rule.
I suspected a drive overheating problem myself. But that wouldn't explain
why I had the same problem when I switched to a fresh machine. Basically,
after 2.5 hours, the old machine crapped out. So I unplugged the
(potentially overheated) work drive (glyph studio mini) and hooked it
into my cold laptop - and then the* laptop'*s boot drive started running at
32MBps read speed too - even though this was a cold drive. The problem
went away after I spent an hour resetting the permissions in the terminal,
repairing permissions in the disk utility, and then manually changing the
permissions on my adobe folders.
I was working on 4k red raw footage in a 1080 timeline rendered out to a
pro-res sequence with preview files living on my work drive. I know that's
processor intensive (especially since I only have 512MB Vram in my graphics
card), but is that going to overheat my drives after 2 hours?
Also- on my older machine, I write my media cache files to an additional
internal drive to make it easier on the boot and work drives. The newer
laptop has the media cache copying to the work drive. Don't know if this
is relevant at all
I see a few potential issues.
- OS X 10.7.x is not supported with Premiere Pro CC 2014.1 (8.1). You need OS X 10.8.x, or later. Please update your OS (and related drivers and plug-ins). I recommend OS X 10.8.5 as I have no issues with it and others on that OS have fewer issues than those running OS X 10.9.x, or later.
- If you are operating Premiere Pro CC 2014.1 (8.1) and have updated the project from Premiere Pro CC 2014 (8.0) or earlier, you may experience issues. Revert to the application version you began the project with. Do not update until you're ready to begin a new project.
- Your GPU is underpowered in the legacy Mac. It would really help to update that to a GPU with VRAM of 1 GB or more since you're working with RED footage.
- Mac OS X can reset permissions of your Adobe folders, as you found out. Please see this article to make sure that you've set all the permissions correctly: Premiere Pro CC, CC 2014, or 2014.1 freezing on startup or crashing while working (Mac OS X 10.9, and later)
Hope this helps.
Huh. Thanks, Kevin. I've had so many conversations with Adobe, and no one
mentioned that 2014 isn't supported for OS 10.7.5. That's helpful.
My issue is that I can't update the OS on the tower - otherwise I would
have done so ages ago. And I like to run both machines on the same OS.
I guess it's the end of the line for that old machine unless I hack it and
replace the graphics card myself.
