Hello, I'm looking for a definitive Storage and Backup solution. So far I've been looking on to Drobo 5D or N, LaCie 5big Thunderbolt 2, or LaCie 2big Thunderbolt 2. Networking would be a plus but not a must. I'm open for other suggestions and also wonder if these systems can be considered backup since they are ready for single or double disks failures. Thanks.
