I used to sell Terrablock, but that was in the Pre-“multi user write” era.
I then worked as an editor at a facility using HDV and PPro with a Terrablock and never had any of the speed issues you were talking about.
we routinely worked from the same media.
are there any media types that don’t exhibit the issue?
as a test…
fromt he terrablock see if you can “eshare” out a volume or media folder as a regular network share over ethernet…
then import media via that mount point (in other words the network share, not what looks like the local volume mounted on your desktop)
I’m not suggesting it’s the solution…
but that might tell you if something about the fibre card, adapter or switch is causing an issue.
i know it’s not much…
but it is something to try…
I’d also reach out to Facilis support, they were pretty good as I recall.
