I do not relish dumping this drive system - but it is useless on the new future of Macs. Nonetheless, the LaCie Techs cannot discern this and the drive currently does do 400+/400+ on the Intel and 55/270 on the M1. The reason I am asking this is if your 5Big (whatever) is performing differently than mine - I have done 2 failed drive swaps over the years and although I have replaced with IronWolf, maybe I have introduced something incompatible or less optimized. I have 3 Apple TB 23 dongles I have 2M and half-metre cables from different manufacturers - I counter-swapped, and all these work fine on the TrashCan - and when connected on the clearest/simplest path on the M1 Mac - much less performance. It's a driver issue - entangled with caches/buffers/optimization and all that.
I swapped every TB2 cable and Apple adapter I have* - so it's not a cable or adapter issue. I spent some hours on the phone with tech support today and they do not have an answer for this. This drive, while readable, is useless for ay serious photographic/video work.
On my Intel MacPro (TrashCan 6,1 Thunderbolt 2) I get at least, 400/400 MB/sec by any measure (transfer a really big video file and stopwatch it, Blackmagic, etc) - but on moving the drive to the M1 my speeds are roughly write 55MB/sec read 270 MB/sec.there is some variability but this is the essence of it - not much better than a USB2 drive and on par with a FW 800.
However, it's performance is seriously impacted. The drive was recognized and I could read and write to it. This time the install under Big Sur went fine - I had to approve the software's source with Privacy as expected and this time it went okay. Today, April 8th, I set aside the afternoon to download and install the RAID driver and physically move my 5BIG from my Intel Mac Pro 6,1 (2013) Thunderbolt-2 to my Mac Mini M1 (16GB ram/2TB storage). 5 few days ago I received a notice that LaCie had issued an update to the LaCie RAID manger that would work under Big Sur 11.2.3. Hope it can help some of you address that issue.Īpril 8 - 2021. Cleaning up these old extensions did the trick.
I restarted my iMac and to my surprise my Lacie 5BIG TB2 came back online :-)īottom line for me, there was an extension that prevented others (like the Lacie one) to get loaded. I then received a notification from Security and Privacy about something was updated (don't remember the exact message) and needed to restart my iMac. I use the System Report to look at all non Apple extensions and see when they were installed, if they were loadable and 圆4.ĭeleted all old extensions that I no longer needs such as Blackberry, Epson and Logitech. When I manually ran the install script, I noticed that I was getting an error when trying to load the driver. When accessing the Lacie Raid Manager, I would get the message that a driver needs to be installed. I have been trying to solve my issue with Lacie 5BIG TB2 and Big Sur on iMac for 2 months.
