I am looking to attach 6-8 additional hard drives with a PCI-e HBA (Host Bus Adapter). I am not interested in any external solutions. I do not need RAID. I do not need to boot from it. Would the ATTO ExpressSAS H608 be the best bang for the buck solution? I can use it in OSX and Windows. http://www.attotech.com/products/product.php?cat=3&scat=4&sku=ESAS-H608-000 I found it online for $302 at Provantage. Anything else that comes close to function and price?
