I'm currently running a Highpoint 2322 external RAID card with an Addonics Mini Storage Tower and 4 500GB Western Digital RE2 hard drives. With all four drives in RAID0 mode I'm getting ~250MB/s bursts, ~170MB/s average read, and ~125MB/s writes. In RAID5 I'm getting similar bursts, but average reads drop to ~70MB/s and write speed drops down to ~50MB/s.
Do these RAID0 speeds look good?
Is such a huge performance hit when going from RAID0 to RAID5 normal?
Here's my hdtach results compared - RAID0 is red and RAID5 is blue.
