Given recent Thunderbolt disconnect discussion, the “can now detect problems which are occurring on the Thunderbolt port of a Mac” point is interesting.

SoftRAID is also bundled with the OWC Thunderbay RAID solutions (see review of OWC Thunderbay 4 and review of OWC Thunderbay 4 Mini).

April 11, 2016 — SoftRAID version 5.5 - Convert Apple RAID volumes to SoftRAID

OWC Holdings, Inc. announced today the release of SoftRAID version 5.5. This update to the highly regarded SoftRAID product allows users to convert Apple RAID volumes to SoftRAID as well as operating in four languages. SoftRAID version 5.5 is a free update for all version 5.x users of SoftRAID.

SoftRAID is the premier disk driver for Mac OS X, and replaces the RAID functionality that was removed from Disk Utility in Mac OS X 10.11 El Capitan. Now with SoftRAID version 5.5, users can convert their existing Apple RAID stripe (RAID 0) and mirror (RAID 1) volumes to SoftRAID and preserve all the files on those volumes. This provides a seamless way for existing Apple RAID users to start using the great features of SoftRAID.

SoftRAID Lite, just $49 — For $49, users can purchase SoftRAID Lite and convert their Apple RAID volumes to SoftRAID. Not only will they be able to start using the highly optimized SoftRAID driver which has been shipping since 2003, but they can also take advantage of all of SoftRAID's advance disk health monitoring and logging features.

Convert Apple RAID stripe volumes to SoftRAID RAID 1+0

Users who purchase the normal version of SoftRAID can not only convert their AppleRAID stripe (RAID 0) volumes to SoftRAID but can also convert those volumes to RAID 1+0. A stripe (RAID 0) volume becomes unusable if a single disk fails whereas a RAID 1+0 volume will continue to function after a disk fails.

RAID 1+0 volumes are a stripe volume where each stripe unit consists of a pair of disks, if one disk in the pair fails, the other continues work as part of the volume.

The SoftRAID application and SoftRAID Monitor now in 4 languages

With SoftRAID 5.5, the application and SoftRAID Monitor now support 4 languages: English, French, German and Spanish. "About 40% of our sales comes from outside the United States" said Tim Standing, VP of Software Engineering. "It is important that we add support for non-English speaking users so they can know the true power and reliability of SoftRAID."

Better logging of errors — SoftRAID version 5.5 includes an entirely new error logging mechanism. "We realized that our old error logging mechanism was occasionally truncating or mangling messages. This made it hard for users to determine which disk was failing" said Tim Standing VP of Software Engineering. "We want to give our users the best tools possible for diagnosing disk problems so we wrote a new error logging mechanism which is much more reliable and better able to handle information for failing disks."

When a disk starts having problems or fails, one of the first places to look for information is the log file. If the failing disk produces lots of errors, the old logging mechanism could sometimes mangle or truncate log messages which made it hard to determine what exactly went wrong. The new logging mechanism can handle many simultaneous log messages without truncating or scrambling any of them. This makes it much easier to figure out which disk is failing and why.

SoftRAID now detects problems with Thunderbolt ports

SoftRAID version 5.5 can now detect problems which are occurring on the Thunderbolt port of a Mac. These problems can cause disks to be ejected while in use. When these errors occur, SoftRAID version 5.5 notifies the user and suggests possible ways to keep these problems from reoccurring. For more information, see:
