I need to connect 4 SED Ultrastar HC550 hard drives somehow, but I don't know what to look for other than low price and number of ports. The drives are less than 285 MB/s each, so I doubt there would be bandwidth limitations. Does the HBA affect use of TCG Enterprise encryption? I was looking at adapters on ebay. There are thousands of listings there, and I'm clueless, so I thought I'd ask for any recommendations or advice.
