LaCie 6Big 48TB (40TB in RAID5). On a Intel MBP I get decent 800+ MB/sec R/W
On an Apple M1 MBP, its 300+ MB/sec read and 50 MB/sec write.
I’ve connected the LaCie 6Big to an Intel Mac Mini. Connected a TB3- 10GigE adapter to the Intel Mac mini. Then connected another TB3-10GigE adapter to my Apple M1 and, of course connected a GAT6 between both 10GigE adapters. And then shared the LaCie 6Big over 10GigE with the M1 MBP. Now I’m seeing slightly better speeds like 300 MB/sec R/W.
I read a discussion on this on the Apple dev forum and there one person posted that he installed SoftRAID 6 on the M1 system and used SoftRAID to create a RAID on the LaCie 6Big and now he’s seeing 1000+ MB/sec R/W.
I dont understand why it is just Lacie having this issue, I have large RAID 5 drives from Areca, G-tch and Lacie, and it is only the Lacies drives that have ridiculously slow write speeds on my Mac Studio M1, if the other drives are running fine why cant Lacie fix this? The Lacie drives currently have too much data for me to shift across to start formatting etc, hope there is a fix or work around soon that doesnt require me to move everything
I’m getting amazing throughput on an OWC Thunderbay8. It’s loaded with SSDs, set up as RAID4 using SoftRAID on an M1 Mini (Monterey). No issues with the software, been running it hard for a few months now. I was apprehensive at first, but it’s won me over.
