Magnetic hard drives retail for $10 to $20 per GB. At that rate 2,300 GB of storage would be worth something like $23,000. So if that much storage can be made for 35 pounds (= $56) it would represent quite a dramatic price breakthrough. Even if the raw access rate were considerably slower than magnetic hard drives, the effective access rate could presumably be raised by reconfiguring the access to be more parallel. It sounds too good to be true.
