Only $420 for 32GB.
Only $420?! They will have to come way down in price before I would
even consider buying one. For $420 I would expect at least 1TB.
Even at that price I'd stick with magnetic, and so would most
buyers. I value the greater life & reliability of magnetic too. I
wouldnt necessarily assume that electronic will oust magnetic any
day soon - it may, but cost & capacity of mag drives are ever
improving as well, so no guarantee electronic will ever catch up.
On the other side I saw a cute 1" hdd on a usb plug back in 08. They
might just take over from flash.
The main drawback now is how many write cycles they can take. It's
low on the lower price units and not great on the better ones.
Hard drives move. The reliability of the modern drive is a wonder
but solid state will be the eventual winner.
but you give very little reason. We know their mechanical nature is a
downside since it leads to shock vulnerability, and we know many
mechanical devices have been surpassed by electronics, but in this
case there are far bigger issues involved. And since hdd capacity is
increasing as fast as electronic memory device capacity, no crossover
point can be even vaguely predicted.
state devices (and the same arguments were used.) It has been the advance of
electronics and solid state devices that has made this possible.
Here's an abstract from 2005 that shows where we are going.
"Summary:Technologies are now emerging to construct molecular-scale
electronic wires and switches using bottom-up self-assembly. This opens the
possibility of constructing nanoscale circuits and memories where active
devices are just a few nanometers square and wire pitches may be on the
order of ten nanometers. The features can be defined at this scale without
using photolithography. The available assembly techniques have relatively
high defect rates compared to conventional lithographic integrated circuits
and can only produce very regular structures. Nonetheless, with proper
memory organization, it is reasonable to expect these technologies to
provide memory densities in excess of 1011 b/cm2 with modest active power
requirements under 0.6 W/Tb/s for random read operations."
Low power means low heat.
If you follow the industry you are aware that up until now solid state
devices have essentially been 2 dimensional. IBM and others have been
moving towards the construction of three D devices.
The web has tons of articles on the advancement of solid state devices.
I expect the near future to show us computers as much different from today's
machines as today's machines are to my first computer and it used paper tape
to store data.
