7. Why are SSDs better than traditional hard drives? What are the drawbacks?
to operate, generate heat, have physical limits to performance (speed, size, and
eventually capacity).
The biggest drawback has been cost, but had also been total storage capacity and
write speeds. Today’s SSDs (as of 2010/2011), most of these problems have been
solved except the price. And, a more subtle issue that current SSDs use a technology
with a finite number of writes per cell. This drawback is managed by the controllers,
and is not a critical issue, but makes the designs more expensive.
