Blackmagic multidock 10G for editing?
-
@Doug and @Joby – thanks for further thoughts on this. I think I’m going to have to go back in this thread and review. The problem persists!
It seems totally unpredictable. No real discernible difference in the nature of my projects (all basically doc-style stuff…no heavy effects etc). Sometimes I go the day with no problems, and then other days I get interrupted DURING PLAYBACK. It can be with 4K or HD. Just watching my sequence and then things come to a halt and I hear the drives spinning, as if they are just starting up. “We’re tired…let us take a little break for 20 seconds while we catch our breath.”
In a situation like that, doesn’t it seem that it HAS to be a drive issue?
As I mentioned before I have the drive formatted as RAID 1. (And yes, I have all media backed up elsewhere 😃)
-
I’ve never had slowdown issues with our Lacie RAIDS (that I know of), but the sleep, no sleep, spin up behavior, has been inconsistent at best over the years. So I’ve stopped worrying about. But in terms of actually becoming a problem during an edit, no problems–they’ve otherwise been rock-solid.
And for the record, all on Macs (both Intel and M1), with the put disks to sleep option off, RAID 0 for ultimate speed (and yes with redundant periodic backups), and all formatted has Mac OS Extended (Journaled) because they’re spinning disks, and a GUID Partition Map.

Well, all of this has me wondering if there’s something in the individual drive’s firmware, or some LaCie software that has a separate control or trigger for spin down.
If you’re formatting / setting up whatever external with macOS Disk Utility, the manufacturer’s software is often unnecessary, and sometimes counterproductive.
-
@Joby and @Doug: again, thanks for your responses. @Joby, you moved a little into tech speak in the second half of your response, but I will try and interpret! @Doug, I think I need to get back in touch with LaCie and perhaps make some inquiries along the lines of what you’re mentioning (and perhaps Joby’s too, once I’ve figured out what he’s talking about!)

And what Doug mentions is key. I too have often wondered about some kind of LaCie specific sleep behaving controller buried in the machine. And wondered if I could access it with one of their apps. But it ultimately seemed a fool’s errand with no value added, so I gave up (plus it seems those LaCie apps wanted to add on all sorts of low-level extensions deep within the OS and again, just didn’t seem worth it to me).
Typically, what I do on any given harddrive it take it out of the box and format it directly with Apple’s Disk Utility (DU). I’m not interested in anything they generally bundle with it, such as security apps or drive controllers, or . . . Now there are other software RAID controllers such as SoftRAID, but I don’t have any experience with it, and Apple’s DU has generally been “good enough” for my needs.
And note, there are instances of hardware-based RAID controllers, but those are typically on more expensive RAID setups that generally use a software app to get to the controls of the hardware. ATTO products come to mind–though there are others.
In terms of the geek speak, the reason I mentioned what I did is because some of the problems you’re experiencing “could be” related to a mismatch of some kind. Like using the Apple Partition Map instead of the GUID Partition Map. Or APFS (on spinning disks) instead of Mac OS Extended (Journaled). Much like the use of 3.1 USB-C vs. the Thunderbolt slot.
One “gotcha” to look out for when using Apple’s DU is the difference between viewing Only Volumes and viewing All Devices. Think of All Devices as the core harddrive (say all 1 TB of a 1 TB drive), and Volumes as sub-parts of the drive (or partitions), where you could have two 500 GB volumes on a 1 TB drive. Volumes that you can mount and unmount independent of one another. Or you could just keep it all as a 1 TB volume, or. . . . But anyway, as you’re playing around with these things, that’s one that can trip someone up, especially when it comes to formatting a drive.
My encouragement would be to unmount (and disconnect) all drives, and then get something you don’t care much about, like say a scratch drive where you can lose everything, and then start poking around at the different ways to format something in DU.
Joby.
