SoftRAID is disk driver software that allows you to create, monitor, and maintain a software implementation of RAID for greater speed and data protection.

Standard Hardware RAID products only protect you from losing files when disks fail. SoftRAID does more by constantly checking your disks and warning you in advance—before a disk fails—giving you time to replace bad disks, saving precious files and data.

Not only do you gain peace of mind knowing that you’ll be alerted about disk problems, SoftRAID will allow you to carry on with work (with all RAID levels over 0) even if a drive fails.

SoftRAID offers 5 RAID levels: RAID 0, 1, 4, 5 and 1+0. All RAID levels above RAID 0 offer data protection and redundancy. RAID 0 does not protect your data, but if you work with large temporary files (such as video scratch data) you’ll love the lightening fast disk access.

Primary Features of SoftRAID 5.6.3

  1. SoftRAID is now compatible with macOS High Sierra, although SoftRAID 5.6.3 does not support creating, modifying or converting APFS volumes. However SoftRAID’s certify, verify and monitoring features do work with APFS formatted disks.
  2. High Sierra includes increased kernel security features which changed the behavior of some macOS kernel functions. This change in kernel behavior could cause disks to hang. SoftRAID 5.6.3 includes driver modifications to ensure that disks do not hang with macOS 10.13 High Sierra.
  3. The SoftRAID driver has been changed to handle disk errors better.  A read error during a cache flush operation could cause a kernel panic with RAID 4 and 5 volumes.
  4. The SoftRAID driver has been changed to use fewer threads, since macOS 10.13, High Sierra, now limits the number of kernel threads which can run at one time.  Previous releases of SoftRAID could cause this limit to be exceeded during disk update operations, causing a kernel panic. The new driver uses no more than 1 thread per disk for disk update operations.
    Fixes to driver loading ensure that the correct driver is installed when installing for the first time, and that newly updated drivers are always loaded. In previous versions it was possible for older, cached versions of the driver to be loaded by mistake under certain circumstances.
  5. The SoftRAID driver no longer reports read errors on stripe (RAID 0) volumes as write errors.
  6. The command line interface of the SoftRAID Tool no longer returns an error every time the disk unmount command is used.  In previous versions, this command, used to unmount all volumes which use a given disk, would return an error even if it was successful.
  7. SoftRAID 5.6.3 also includes numerous bug fixes, details of which can be found in the release notes.
  8. SoftRAID is actively supported and improved

At SoftRAID, we don’t believe that software should be shipped and then forgotten. We are constantly refining and improving our product, because we love what we do and want it to be the best it can possibly be!

SoftRAID: invaluable features at a great price

SoftRAID 5.6.3 features a highly optimized driver, which provides a software RAID solution that equals, and can often exceed, the performance and reliability of dedicated hardware RAID controllers. In addition, users can also take advantage of SoftRAID’s advanced disk testing, logging and disk health monitoring. SoftRAID’s unique disk failure prediction provides advanced warning of potential disk problems, protecting users from catastrophic data loss that can occur when a disk suddenly fails.

At just $179 the full version of SoftRAID supports 5 RAID levels (0, 1, 4, 5 & 1+0), plus email notification of potential disk failure and command line support.

For $49, users can purchase SoftRAID Lite and create RAID 0 and RAID 1 volumes, or convert their AppleRAID volumes to SoftRAID.

Both versions use exactly the same great driver, provide the same disk testing and health monitoring, and are localized for French, German, Spanish, Japanese and Chinese.
