Ssd is simply a disk that doesn t have moving parts and flash is the implementation that allows that to happen.
Flash storage vs ssd.
Usb thumb drives have used flash storage for a long time as well but the quality of the flash storage in those is typically much lower than the flash memory used in ssds.
Because it uses integrated circuit technology flash storage is a solid state technology meaning it has no moving parts.
Modern ssd hard drives are flash based so today there s not really a difference today between ssd and flash.
The main difference is that flash storage has moving parts.
Both of them have the same hardware software.
Ssd just means a hard disk that doesn t move.
In both the case discussed above the latter one is a type of the former one.
Flash storage vs ssd for type 1.
When flash technology is used for enterprise storage the term flash drive or flash array is often used interchangeably with solid state drive ssd.
Flash storage or flash memory is the eggs parts of the analogy.
Most ssds solid state drives are made mostly of flash memory like an omelet is made mostly of eggs but flash memory can be.
Ssd solid state drive solid state drives use flash memory to deliver superior performance and durability.
Comparing the flash to the ssd is much similar to comparing the batteries with the lithium ion.
