Bob is right on the money in regard to Highpoint’s support department. It just doesn’t exist. On the other hand, if you absolutely need RAID 5 and are not in a position to ditch your Sonnet array for MiniSAS or Thunderbolt, you will have a hard time finding a reliable and well supported alternative in the market. You can also check with vendors such as Promax to see what they offer in terms of RAID 5 in eSATA. It may be worth your while to purchase the controller from a vendor that will back the product with support.
