I'm presuming that SoftRAID Lite doesn't verify AppleRAID volumes. So the only way to verify my current AppleRAID volumes, while on El Capitan, is to have SoftRAID Lite convert them to SoftRAID volumes? As was mentioned in the another post in this forum, said feature is coming sometime this month? This is the only reason that I might consider buying a license since Apple threw AppleRAID out the El Capitan window, possibly out of a misguided trust in the reliability of a single flash disk.
Another question I'd like to throw out there. Can you break a SoftRAID mirror (RAID 1) like you can with AppleRAID?

Yes we will have the "Convert to SoftRAID" feature in the next update, in a couple weeks. This will allow you to convert an existing Apple volume to SoftRAID.
One difference with Apple RAID and SoftRAID is there is no way to ensure an Apple RAID is in sync. There are several bugs in Apple's implementation, where an Apple RAID mirror where disks are disconnected can be a disaster. SoftRAID understands how to manage disks that are removed from the system and keep the volumes independent disks in sync.
A Validate will read each disk and compare them, so the user have verification that each of the mirror disks are 100% identical. Generally, once a volume has been validated once, it will not ever need to update sectors on subsequent validates. (Note: when an SSD with TRIM enabled is part of the mirror, validate will actually correct sectors each time! This is not a bug, it is a consequence of how TRIM works.)
It is our opinion that Apple removed Apple RAID in El Capitan primarily because the RAID driver had not been updated in 6 years, and there was no one to work on it, which forced their hands when Disk Utility was redesigned.
Lastly, yes you can split a SoftRAID mirror.
SoftRAID uniquely allows multiple disks to belong to a mirror, and each secondary disk can be moved off-line and act as an archive. Disks can easily be added or removed from a Mirror. SoftRAID's mirroring implementation is very flexible.

It's been about a month since I last posted. I just bought a license for SoftRaid Lite and expected that 5.1.1 would be the update which would enable converting AppleRAID volumes to SoftRaid. Disappointingly, that is not the case. The 5.1.1 Release Notes list this "bug":
The function in the SoftRAID application which allows converting AppleRAID volumes to SoftRAID is not yet implemented
So, when exactly is this coming?

Soon. We had to upgrade the development environment to the new El Capitan Xcode and are still dealing with issues in supporting all OS X versions that SoftRAID needs to support (10.6.8 up). We should have a beta around the first of the year if all goes well.

Is the beta available yet?

We are getting close!
We will post when we have a beta available.
