"A few problems exist with the technology, for one it
is susceptible to movement, magnets, electric shock, or just wear
and tear. When they fail they tend to fail hard and often your data
with it. They are also bulky, so if you want something in your
pocket hard-disks just won't do. But there wasn't any viable
alternative that equaled hard-disks storage, performance, and
price. Indeed, if you do a casual look on Newegg you will find
plenty of 500GB or even 750GB for under $200 (this is looking
primarily at desktop performance, so SATA drives no SCSI or SAS).
"Anyone who has been watching knows that the price of HDs has
dropped dramatically in recent years. A couple of advantages to SSD
is they are quiet, light, resilient to movement, and tend to take
less energy to run. This makes them perfect for laptops, which is
where, as the article notes, we have seen the boom in SSD
technology."
