I'm just passing along the info for those who are interested. I don't know what the cost will be. I know people have asked about an LSISAS2X36 based expander in the forums, so now (or soon) there is an option out there. I know the Astek one also has SES-2, fan monitoring and control...
Probably as much as a bleeding edge video card ;) I'm sure it will be more than HP or Areca, but affordable for those who want the higher performance. I will keep you posted on what I find out.
FYI,
Wanted to let everyone know who is interested:
http://www.astekcorp.com/index.php/Products/A33606-PCI.html
Press release was on 4/14/10. Looks like it can be mounted in PCI(e) slot or purchased in a 5.25 in chassis.
Has alot of additional features that the others don't have...
