A lot of people have been asking us the differences between a SSD drive and a normal HDD ; on how much impact will it make to their usage so here are some quick notes gathered from various sources:
An embedded system is supposed to operate like an appliance. When you turn on a microwave oven or
TV, you don’t expect to wait half a minute for it to boot its operating software from a disk drive. You want
it to perform its intended function instantly. Such systems, if they contain microcontrollers, normally load
their software instantly from a ROM, not from a disk drive.
A solid-state drive (SSD), sometimes called a solid-state disk or electronic disk, is a data storage device that uses solid-state memory to store persistent data with the intention of providing access in the same manner of a traditional block i/o hard disk drive. SSDs are distinguished from traditional magnetic disks such as hard disk drives (HDDs) or floppy disk, which are electromechanical devices containing spinning disks and movable read/write heads. In contrast, SSDs use microchips which retain data in non-volatile memory chips and contain no moving parts. Compared to electromechanical HDDs, SSDs are typically less susceptible to physical shock, are silent, have lower access time and latency, but are more expensive per gigabyte (GB). SSDs use the same interface as hard disk drives, thus easily replacing them in most applications.
The below video was out in 2009 when samsung was showing off their SSD drives and it pretty much gives a good overview on how things change with SSD drives
A solid state drive will improve overall system performance, run cooler, and quieter.
This detailed review of the impact on SSD drive for gamer’s proves that the performance in all aspects increase but the costs are still higher than a regular HDD.
We will be features a few systems featuring SSD drives inbuilt soon so keep a watch out on this space.
