Does anyone know the difference between these two cards?

From my googling the only thing I've found is "The SGL version doesn't include cables" but I find this wrong since the non SGL, more expensive card, appears to have a DIMM on it or something that the SGL version does not. Is this possibly an un-advertised cache? I wish I could find a comparison of benchmarks between a standard and SGL of the same model to see if its worth the extra cash. :(
 
Lol yes, but it also comes with a DIMM in the bottom right part of the card by the SFF connectors. WHAT DOES IT DO!? Why does Highpoint have such crappy product documentation to not address this? :)

i just noticed that after i posted.
 
That is not a DIMM on the card, though it does appear to be DRAM. So if all else is the same it appears that the more expensive unit comes with an on-board cache, which the cheaper unit does not appear to have. I would be suspicious of the cheaper unit's claim to support RAID-5 as this usually requires RAM for the embedded controller to be installed on the card (which i do not see).
 
I think I found what it is. The SGL version does not support RAID 6 judging from comments, although it claims it does. Horrid documentation it is...
 
You need a crystal ball to figure out which product is which. I was looking in to highpoints to play around with, and gave up when cause I couldn't figure out what was what.
