yeah, not raid. I don't do anything with the performance boost in writing and reading speeds that raid offers. Not so many clients are using the server simultaneously that raid would be worth of risk losing data. I have heard some horror stories about those poor ones who have lost all the data...
Migrating won't be an issue. I can anytime detach a hard drive from the setup and that's fine. The data from the detached hard drive is fully usable. I can put the drive another pc and read the data if I need to do that in case of system failure. Data is not striped across the array
I have 8 data drives, 2 parity data drives and a system drive where the OS is running. Ubuntu 16.04.5 LTS
All data drives are 3 TB in capacity except two that are 2 TB
Correct if I'm wrong but in raid 6 data is distributed across the disks. My data isn't. I wanted an option to expand my setup later so I chose not to stripe data. I was afraid of hardware failure causing to lose all the data in case I couldn't find similar hardware to replace the failed ones...
Daily. Every night 1am computer checks its data’s integrity and if corrupted files or data rot are detected, parity data is used to rebuild corrupted files. Computer tolerates simultaneous failure of two disks.
If a disk suddenly breaks down, I lose data I have stored after last night in case...
