The performance estimates I gave you are average gain across client apps, individual applications can see more benefit from higher CPU speed but it depends on whether you care on average performance or perf of specific apps (depending on your usage model). Using 7200 RPM disk may work if speed and not power is your main target. Flash disks have some power advantage for laptops (may be few miutes longer battery life). However, with storage I tend to be bit cynical and care about reliability more. Today all storage mediums have a long term reliability problem, and as our data volume keeps increasing, burden of preserving that reliably is on the shoulder of user, a much harder problem than most realize. A good solution I have seen for this is keep a back up in the house with good reliability (RAID or regular backup), another copy in your safe deposit box that is updated say once every quarter, and a third one geographically isolated copy in another part of the world that is updated once every 2-3 years when you visit that place. This way one gets diversity in time and space. If the house burns down/or broken into, you can fall back to the copy in your locker (losing a quarters data, lesser disaster), if the house burns down and the city where you live runs into some disaster (think Katrina) you can fall back to your distant copy losing about last 2 years data, still better than losing it all....though it assumes you make it alive through these disasters, need to have some positive thought there somewhere :-)
