    Extreme low HDD write performance when enable RST with SSD Cache on Q87

    Painkiller

      Hi,

       

      HP EliteDesk 800 G1 desktop PC with Q87 Chipset. OROM version 12.5.0.1815 in RAID Mode. OS running Windows 7 64 Bit. RST Driver Version 13.2.4.1000

       

      With SATA3 HDD ONLY, HDD Sequence read/write : 78/69 MB/s which is normal.

      With 30GB Sandisk U100 SSD plus same HDD and Acceleration Mode: Enhanced. HDD Sequence read/write : 184/17 MB/s. The Write speed is more than 4 time slower than without SSD Cache.

       

      So, What's I doing wrong here? Thanks in advance.
