Would SSD be better then HDD?

Base on current fast developing flash drive tech,
SSD could provide (up to 160GB) not smaller than the current-used HDD in our
PC.

The favorite part may include its fast reading speed and lower power
consumption.
But besides its high price,
its slow writing time may make consumers hesitate to replace their HDD with
it.
(around 18 MB/s compared to over 50 MB/s for hard drives)

However, with the newer nonvolatile storage developed (such as PRAM),
the situation could be changed.
