Q: 2. Does this hard drive work with USB C ?

A: No, it will only work on Thunderbolt.

Q: 3. Is this compatible with M1 Macbook Pro Max?

A: The OWC ThunderBay 4 48TB 4-Bay Thunderbolt 3 RAID 5 Array is compatible with your Mac.

Q: 4. Can you use this RAID on a 2013 MacPro with an Apple Thunderbolt 2 to 3 adapter?

A: If your macOS is macOS 10.12 or later, yes. You can use Apple's Thunderbolt 3 to Thunderbolt 2 adapter for compatibility.

Q: 5. If removed drives are cared for and labeled, can I re-insert the disk pack into any Thunderbay at later point to mount volume?

A: The OWC ThunderBay 4 32TB 4-Bay Thunderbolt 3 RAID 5 Array (4 x 8TB) BH #OWTB3SRT320S uses a software RAID. This means the array is not bound to specific hardware. However you must be very careful in the steps and procedures followed or you could end up with data loss.

Q: 6. What is the difference between Raid 5 and Raid 5 Enterprise. Also does it come with a cable?

A: The Enterprise version comes with server grade hard drives. These are built for 24/7 operations with drives that are designed to run continuously. Cable is included.

Q: 7. What is the difference between this model (JBOD) and the slightly more expensive RAID 5 Edition? I realize the Raid 5 Edition comes pre formatted as a RAID 5. But it looks like you can format the cheaper option as a RAID 5 via disk utility. Is it just the SoftRAID software that comes with the RAID 5 edition? Which leads me to my second question, do you need SoftRAID to rebuild a lost disk and run the RAID 5?

A: The only difference is the RAID software. Apple RAID cannot create a RAID 5 array, it can only create RAID 0 and RAID 1. The latest Mac OS cannot create a RAID array at all, this feature was removed from Disk Utility.

Q: 8. Will this work with Windows 10 in RAID 5 configuration?

A: I'm sorry, no, Windows is limited to RAID 0 and RAID 1 for the time being.

Q: 9. Is it possible to swap disk packs and preserve the data?

Q: 10. What is the difference between the 20tb and 16tb. Seems to be a jump in speed from roughly 500mb/sec to 1000mb/sec is this true in a raid 5?

A: I just looked at the benchmarks for the 20TB model, and I do not see anything that suggests 1000MB/sec performance under any circumstance. Both of these should be in the mid 500MB/sec range in RAID 5.
