Good disk set up.

[Dredgy]

Just canvassing opinions. My computer acts as an all in one (gaming, workstation and NAS) and the centerpiece to it has been it's storage array. The main mass storage array (4x4TB drives) failed - one of the drives seems to have died at the PCB level. The main array was set up in a software "RAID 0" array after previously being in hardware RAID 10. The big problem was, when one of the drives failed, I got NO warning and could use and access most files fine and slowly but surely they became corrupted. By the time I figured something was wrong, essentially all files were unrecoverable. My scheduled backup drive (networked) failed too, but my local USB backup survived so I haven't lost any significant data. My main working drive - operating system and applications is fine. 

 

So I've now pulled the main array (other disks from same batch so not gonna risk reconfiguring). I need a new solution.

I want at least 6TB of storage. I would like some immediate redundancy. Budget is $500-1000 (AUD). These are my options:

1. 2x 6TB drives in RAID 1. Easy. Surprisingly expensive. If not in RAID, have one schedule backup to the other. Either way, hardware cost is the same.
2. 4x 3TB drives in RAID 10. Fast, redundant enough. Much cheaper than the 2x6TB option for same amount of storage. Can't be expanded later as that's all my SATA ports taken
3. 1x 3.84GB SSD. Wayyy above budget and doesn't meet data or redundancy requirements, but fast and silent. Can always add more later and damn reliable. Any recommendations for cheaper, high capacity SSDs? A 4x 2TB SSD array would be acceptable.
4. 1x 10TB drive. These tend to be for surveillance or NAS use. I write and read from the drives everyday, so not sure how ideal they'd be. Can add a second later for much higher capacity. Probably prone to failure and no redundancy.

Any thoughts or recommendations? Other suggestions? The hard drive market seems quite stagnant atm.

 

 

Thank you.
