The initial transfer to my new 5N is underway, but I’m having issues. I don’t think it’s the Drobo itself.
I plugged it directly into my MacPro and tested it with Blackmagic Speedtest and it was 90-100 MB/sec which seems great. As soon as I try to copy files from my firewire drives though it seems to slow majorly. I’m even trying a utility called ultra copy to avoid errors, etc with no luck.
Any ideas on how to speed this up? Could it be packet size, etc? Would love 100 MB speeds, etc.
A couple things - the Firewire drives are likely going to be a bottleneck. Even FW800 doesn’t usually hit its full theoretical speed (it tends to be limited by chipset or drive speed). After that, once you’ve written enough data to the Drobo it starts optimizing the layout internally, so the early days of using it tend to be a bit slower; performance then returns to normal after a bit.
Most drive cloning programs (like Synk, CCC, etc) don’t work with network volumes like the 5N. They need lower-level access than a network protocol like AFP allows. Best advice would be to use the Finder in smaller batches if you’re worried about a single file tripping it up.
