Does SoftRAID support encrypted volumes?

Mac
Yes SoftRAID supports encrypted APFS volumes, although indirectly. Any SoftRAID APFS volume can be “erased” in Disk Utility, as APFS encrypted.

Note: HDD RAID 4 and RAID 5 volumes are very slow at present, we are working on this issue.

Windows
Encrypted NTFS volumes are fully supported.
