people here are so pumped up bout da fakeness of 400GB but no one mentioned any technical details on how they'd make the OS detects it as 400GB

this is because the actual Physical memory is only a mere 1GB or abit more than that,however wht makes the OS detetcs it as 400GB is due to virtual memory.Just like ur PC..u have the physical 4GB RAM tht u install but do u know tht in Windows they have the virtual memory ? u can set to whatever size u want...

virtual memory replicate the use of RAM where data is temporarily stored before they are being processed.Same goes with Virtual memory.They only hold the data for that moment..but the moment u unplug the power,ur data is no longer there 

So please dont be fooled by some greedy tactic by stupid company who just care bout money 

Some things are just too good to be true
