I apologize directly for my english, I come from switzerland.
I am trying to put a Usb key (8GB) under ZFS to try it out. So I just did it with the quiet good explanation and a little research on the forum. But one porbleme juste arrise, I can not write to the usb stick...
"Impossible de déplacer l’élément « test.jpeg » » car « USB » ne peut pas être modifié." so basicly it said that it can not move the "test.jpeg" because "USB" can not be modify.
I tried to change the permission on the disk but it didn't work...
When I do the "ls -l /dev/dsk/":
total 8
lrwxr-xr-x 1 root wheel 12 1 nov 19:32 GPTE_ACC137A1-11FC-4A51-8962-89446ACBC79A -> /dev/disk2s2
An other question ( I think it's better if I ask all the questions in the same post

I have a macpro with 4*1TB in raid 0, I was thinking of changing my setup to 1*256GB SSD + 3*1TB in raid 0. Will it be a good idea to make the 3*1TB a Raid under ZFS? I do a lot of digital photography and animation and search the best way to reinstall my setup.
if somebody can help me, a new academic in comunication and computer science will be very thankful
