Designed as a workhorse external storage solution, the ThunderBay 4 4-Bay Thunderbolt 3 RAID Enclosure from OWC / Other World Computing can handle multi-stream compressed 4K video and other bandwidth-intensive operations. Built with four SATA drive bays that can handle 2.5" or 3.5" hard drives and SSDs, the ThunderBay 4 delivers sustained data transfer speeds of up to 1527 MB/s in RAID 0 and connects to your host Windows or Mac system using a Thunderbolt 3 port, while a second Thunderbolt 3 port can be used to daisy-chain up to six ThunderBay 4 enclosures. There is also a dedicated DisplayPort 1.2 port that supports a 4K display. Thanks to the SoftRAID software RAID controller, the ThunderBay 4 can be configured as RAID 0, 1, 4, 5, and 10, each of which provides data redundancy, performance, or a combination of both. For those who do not require a RAID, JBOD is available.

I purchased one of these units - along with 4x16TB 3.5inch drives, and am running this in Raid 5. I have filled up the drives and just wandering - Can I purchase 4 new drives and set it up as a fresh Raid-5, but still have the option in the future to plug back in my old drives and access the data? Will the enclosure recognise previously created volumes?
In order to create a new RAID setup with the OWC ThunderBay 4 4-Bay Thunderbolt 3 RAID Enclosure, you will need to purchase the SoftRAID XT software from OWC. That will allow you to have a new RAID setup. But when you put in the old drives, the enclosure will recognize the old drives. Make sure that you number the drives and input them in the same bay as removed.

Can I use the thunderbay enclosure with several sets of HDDs? for ex. projects 1, 2, 3 on separate multi-HDD volumes I can swap
Once configured in a RAID array, drives should not be removed from the enclosure unless absolutely necessary. Changing the order of drives or removing functioning drives while the enclosure is active could damage the array and cause data loss.
