I have just purchased 2 x D5 thunderbolt 3 systems and want to use 4 x 10tb Seagate drives and 1 x 4tb Seagate drive in Raid 0.
Every time I try to format the raid, it only sets the raid to 20tb and uses 6tb from each of the 10tb drives and does not use the 4tb Seagate drive.

If I take the 4tb drive out of the unit then I can set the Raid to 0 using all 4 10tb drives.

Do all 5 drives need to be the same size to be able to create a raid 0 using all 5 slots?

Any help would be greatly appreciated.

RAID 0 means you will lose ALL your data in case of a single drive failure (and it will happen). RAID 0 usually requires the same sized drives depending on the implementation.

there is no redundancy for a raid 0, and the total capacity will depend on the smallest hard drive.
