SSD stands for Solid State Drive – they do in a sense use thumb drive technology as they use NAND flash memory to store data the main difference between flash drives and an SSD is a SSD generally uses top grade flash memory and a multiple internal channels (like an internal RAID array) to allow massively faster read/write speeds.
SSD’s main benefit is they have an insanely fast random seek time – ie < ms even on low end drives (i believe on higher end drives closer to .ms) whereas a regular RPM drive typically wil have a random access time of >ms this allows applications to load much faster – especially when combined with their huge throughput.
The other benefits of SSD’s is as they have no mechanical parts so they are less susceptible to shock, generate almost no heat, and use less power.
The main disadvantage of SSD’s is that they cannot be written to as many times as a magnetic platter can be so they require some extra house keeping on the hard drives part which in the case of older generation drives would cause the drives performance to deteriorate over time (although still typically to speeds > the fastest k rpm mechanical hdd’s)
It is SSD which stands for Solid State Drives.
They contain no moving parts and the price per GB is at the moment more expensive than conventional drives.
Battery life tends to improve on laptops as the battery does not have to power a motor for SSD
