For those wanting to make a bigger amount of data readiness by linking them up, in Windows 10 this is available by using the setup/manage of the connected drives. Generally but even largely more 3 minimum can be managed as a single drive.
See this link:

Drive failure can help from losing large amounts of dat until another drive can be added. See the first section of the link for possibly up to 7 drives and as few as 3. Then nyou can follow the instructions below that section.
Personally I use a bonifide 3.0 USB port from a computer and a USB powered Hub from Rosewill to connect up to 4 and then doing them same again with another USB 3.0 port on the computer to get 8 ports. That would satisfy a large storage layout which requires at least three drives to protect you from a single drive failure and at least seven drives to protect you from two drive failures. I cannot tell you the resulting size but it is elastic. (https://www.rosewill.com/?s=usb+3+hub)
