SoftRAID 5.0.5 Released

See also Software RAID Performance with SoftRAID 5 as well as recent tests of the OWC Thunderbay Mini using SoftRAID.

A few of the release notes in SoftRAID 5.0.5 are interesting:

  • Your Mac may hang at shutdown if your remove a SoftRAID disk while your Mac is running. This bug only occurs if the disk is connected via SATA (or SATA over Thunderbolt) and you are running Mac OS X 10.9 or 10.10. We have tracked it down to a problem with the Apple SATA driver and are currently working with Apple engineers on a fix.
  • RAID volumes on USB disks are unreliable. We believe this is due to bugs in Apple USB driver and are currently working with Apple engineers on a fix.
  • There is an incompatibility between VMWare Fusion and SoftRAID volumes. We are currently investigating this
  • The SoftRAID driver now logs any illegal requests it receives for SoftRAID volumes. Log entries are written to the softraid.log file. This logging was added to help investigate bugs in other applications.!
  • Added code to detect modification of the SoftRAID application and driver. Users who run MacKeeper were unable to mount SoftRAID volumes when running Yosemite, Mac OS X 10.10. This was the result of MacKeeper modifying the code in the SoftRAID application and driver. This version of SoftRAID detects these modifications and tells !the user to download a new copy of SoftRAID.

MPG: Stick to Thunderbolt for RAID (or internal drives or SATA or miniSAS on older Macs).
