Can I use an NTFS-formatted drive from a Windows PC?
Short answer: Not as the fast drive. macOS reads NTFS but can't write to it, so nothing can be moved there. Back the drive up and erase it as APFS in Disk Utility, or give it a separate APFS volume.
Not as your fast drive. macOS can read NTFS drives but can't write to them, so nothing can be moved onto one. To use it with Storage Studio, copy off anything you want to keep, then erase it as APFS in Disk Utility.
If you need the same drive to work with a Windows PC too, you can split it into two volumes in Disk Utility — one APFS for Storage Studio, one exFAT for sharing.
