The SoftRAID Monitor generally uses less than 0.2% of your Mac’s CPU power, even when you are using SoftRAID for both your startup volume and all your data volumes.
The SoftRAID driver only uses CPU power when you are reading or writing files. Reading and writing to RAID volumes usually uses less than 4% of the CPU power of your Mac. This increases to about 10% of the CPU power when writing to or rebuilding RAID 4 and RAID 5 volumes.
In addition, all parts of SoftRAID will usually be using less than 200 MB of your physical RAM (less than 100 MB if you are not using RAID 4 or RAID 5 volumes).
We have designed SoftRAID to have as little impact on the speed of your system as possible.
