Creating an SSD raid with an older Thunderbay 4 TB2 enclosure

New Member

I currently have a thunderbay 4 TB2 enclosure with 4 2TB drives +1 cold spare in a raid 5 config giving me 6TB of useable space. I was using it on a 2012 iMac via a TB1 interface for video editing until recently when I tried to move it to a new 2019 imac and the volume became corrupt. Fortunately, I was able to get my data off of it but I now need to rebuild the raid to use again on the 2019 imac via an Apple TB3 to TB2 adapter and want to take the opportunity to upgrade since I have to rebuild the raid anyway. I was hoping to add 3 2.5 ssds in a raid config to be used for video editing and leave 1 slot open so that I can periodically insert 1 of the 5 2TB 3.5 inch drives that I'll have left over for the purpose of short term archiving of less essential media. Here's the questions I have:

1) Overall does this plan make sense?

2) What would be the appropriate raid level to leverage the speed of the ssds for editing and get the most bang for the buck (primarily really short HD projects, occasionally 4K, on AVID) and maybe provide some level of protection against a single drive failure if possible.

3) Would I need 2.5 to 3.5 adapters for the ssds? The current thunderbay 4 says you don't need them but mine is an older model and I think I might.

4) Which 2TB 2.5 sata ssds are compatible and well suited to this purpose?

5) Alternatively, does anybody ever run 3 ssds in a raid 0 and add 1 standalone spinner to back up the ssd raid set perhaps nightly with Carbon Copy Cloner or something similar?

Any advice would be greatly appreciated.

I would go with RAID 0, with nightly backups. Assuming you can afford one day's work lost. Much faster performance.

You are correct the older enclosures do not fit SSD (2.5") drives, the newer ones do. You either need adapters, or new brackets.

Our own SSDs are very fast and reliable. Plus we can test them with our hardware.
