Hello all, I'm at my wit's end with this one--any help/insight will be greatly appreciated. I have a:
5,1 Mac Pro 1X Quad core 2.66ghz CPU
24GB Ram
64GB SSD (system drive)
640GB HDD (user data)
5x 2TB RAIDZ1 array (mostly audio, some video)
I do mostly voice-overs with a bit of audio production for video (and on the rare occasion video editing). I had a Solaris/OI box that housed the RAIDZ but with ZEVO I finally migrated everything over to the Pro (boy that was a pain!). Now everything seems to be working and working well. I get acceptable performance and much lower latency using the RAID locally instead of over a 1Gb connection.
However, Apple Logic is starting to do screwy things. Occasionally it will stop recording (bear in mind this is laying down one track of audio) and tell me my system can't keep up. I've also have some intermittent distortions that sound like write failures. Everything is intermittent and I'm pulling my hair out--ok, mostly bald already so instead I'm just vigorously rubbing my scalp but you get the idea.
Would adding an SLC SSD ZIL fix the issue? Honestly in all other instances the setup runs like a champ. I scrub and get no problems. Read/writes are fast enough for my needs, etc.
