Hello, I'm looking for some Mac storage advice. I currently run a Windows-based household and will be switching to Mac. I have a Synology DS1511+ with 5x3TB HD running in SHR with 1 disk parity. That has a 1.5TB USB2.0 drive attached for selected backup. I'm not currently using an online backup service. With the Mac shift we will have an iMac and a Macbook plus iPhones/iPads. I think I'd rather have my storage be direct connected to the iMac vs NAS. I'm looking at the the G-raid 8TB Thunderbolt device for that. I'm thinking I'd buy 2 of the G-raids to maintain a redundant copy of my data and then also subscribe to Crashplan or something for offsite backup. I'll probably also throw a Time Capsule into the mix for actual Mac system backups. What I'm unsure of is the best way to create that redundant relationship between the 2 G-raids. The options seem to be: 1. Use Mac disk utility and do a raid 1 out of them. 2. Use a program like Chronosync to do nightly backup/syncs. Using disk utility with raid 1 makes for continual, always running sychronization. I wonder if this would create a performance hit though. I'm mainly concerned about the software raid connection though. Is there any way my iMac could fail or that raid could fail, it damages the array, and I do lose data? Using Chronosync seems safer in that respect as the disks are mirrored daily, yet remain operationally indepedent from each other. With the raid 1 array, can I disconnect one of the G-raids, just plug it into another machine, and access the files? Thanks!
