I ordered the 3.4, 4gig, SSD+2gig iMac the other day. Im starting to think this was the wrong decision. Heres my problem; Its shipment is stated as 4-6 weeks. Theres reports that they use Samsung SSDs (?) and i have read they are underperforming other (intel) SSDs by a great degree. I dont know for a fact because the only sources are in reguards to the macbook pro 2011. And I have not seen anyone getting their BTO SSD iMacs yet. (4-6 weeks). So no confirmed reports what brand of SSD the 2011 iMac uses. So I am in a bit of a pickle in reguards to modifying my order to only 2 TB drive and fit an intel 510 series SSD put in at my local apple reseller instead. I have done the numbers and the drives are about the same price. but if the Samsung SSD is such an underperformer in comparison to the intel 510 series... Anyone have any data at all on the SSD in the 2011 imac?
