OCZ Core SSD Raid – Highpoint RocketRaid 3520LF PCI-E x8 controller

3520LF Raid 0 Block Sizes Compared

I decided to compare the raid 0 performance when different 3520LF controller block sizes were used in the creation of raid 0 arrays. The following block sizes were tested:

  • 16K Block size with default NTFS 4K cluster
  • 64K Block size with default NTFS 4K cluster
  • 128K Block size with default NTFS 4K cluster
  • 128K Block size with default NTFS 16K cluster
  • 256K Block size with default NTFS 4K cluster

Advanced Performance was enabled on all tests.
