My Problem is RAID50 slow speed.

Initial RAID Configuration:

  • Disk Drives: 6 HDD TOSHIBA MBF2600RC (600 Gb, 16 Mb, 10025 RPM, SAS, 600 Mb/s)
  • 2 Spans
  • Motherboard: SuperMicro X8DTU-6F+/6TF
  • RAID Controller: SuperMicro SMC2108
  • Virtual Group: RAID50
  • Polices:
    1. Access: RW
    2. Read: Normal
    3. Disk Cache: Enable
    4. I/O: Cached
    5. Disable BGI: NO
    6. Default Write: Write Through
    7. Used Operation System: Windows Server 2016

Result:

CrystalDiskMark Metrics:
Read [MB/s]: 221.5
Write [MB/s]: 38.30

Ubuntu Live CD Metrics:
Read [MB/s]: 270.1
Write [MB/s]: 49.5

Question:
What can I attempt to increase Write Speed?
Should I reconfigure RAID50 settings, or configure different type of RAID?
