    Very poor performance RAID 1 with SSD Cache


      Hi all,


      I've got a rather frustrating problem since I upgraded to WD Purple 4TB drives and also upgraded from Win 7.  Previously I had 4xSeagate 1TB drives in RAID 10 + OCZ SSD Cache enabled.  I upgraded because I needed more space to 2xWD Purple 4TB WD40PURX drives + the same OCZ SSD Cache drive.  When copying data from 1 partition to another on the RAID array, I am getting 10MB/s write speed max and massive response times.. If I run IOMeter I get huge read and write speeds (300MB/s each with 80,000 IOPS) so I know that the Cache is working.  I am not sure why real world transfers are stupidly slow for? I never used to have these issues previously with Windows 7.  I downloaded the latest Rapid Storage drivers today too. 


      Motherboard: Asus P8Z77-V LK with latest BIOS

      Intel Core I7 3770, 16GB Ram

      Windows 10 64 bit.


      Cheers, Mike
