Some problem with RAID-5 energy consumption and CPU use in ZimaOS 1.2.5

Just installed ZimaOS 1.2.5 stable release on my ZimaBoard 832. Since I’m still testing the OS I decided to recreate mmy RAID storege from zero. After my RAID 5 (3x4TB SSD total 8TB) has been created I realised that the energy consumption almost doubled the one needed in ZimaOS 1.2.4.
Also tried to create RAID 0 and I noticed that the energy consumption of the system has returned to its initial level. I think the problem is that CPU in the case of RAID 5 is always busy at list at 25-28% while in RAID 0 it is used by 7-9%. The problem is that I’m totally sure that in ZimaOS 1.2.4 also the RAID 5 consumtion was around 7-9% (what after update in happening only under RAID 0).
Anyone knows why this is happening and how to fix? Thanks
