![]() Much less expensive than a hardware RAID solution.You don't have to reformat to convert to a SoftRAID volume.Lets you easily create and modify RAIDs dynamically - add or remove disks at will.Here are a few of the more notable pros to using SoftRAID: So why should you buy this tool when Apple already gives you free RAID functionality with Disk Utility? The SoftRAID website has quite a list of ways in which SoftRAID is better than Apple's RAID, but is it really worth it?

You could also use the command line utility diskutil to check status of raid devices: " diskutil checkRAID". This does not apply to Apple's Xserve or Xserve RAID, which can email notifications and alerts. On the other hand, if you have RAID sync problems with Apple's RAID, you would not receive any kind of notification - you would only find out if you happened to open Disk Utility and check the RAID status.

You can also easily add and remove disks to and from a RAID.
