popatim, I live in Georgia and here are not such firms, I must import all hardware from USA ) that's the problem.
Yeah, I want to rent some space and so get some little money for family.
I want to store file server in 99.9% uptime datacenter wich offers such services as colocation.
SATA drives are cheaper then SAS drives, that is why I'm choosing sata drives and as backup raid mirrors data as I know and that's good idea tu use as backup
idk much about RAID controllers and server side hardware for file servers, that is why I'm asking for help here, I've googled but didn't found right answer on this
