With the latest EFI firmware update apparently fixing the SATA III problems and the Samsung 830 meeting rave reviews out of the gate, do you think I should RMA my perfectly performing 470? The 470 has been solid for me, but the M4 seemed a bit faster. However, I used Snow Leopard with the M4 and Lion with the 470, that could have something to do with it. Like many, I wish to be on the vanguard of technology and to upgrade to the 830 would be without cost, merely patience. The 830 is expected to be the price that the 470 is now. Do you guys recommend this move? Or do you expect the 830 to be met with problems from the outset?
