What is the difference between HDD, SSD and GDDR Type of memory technologies?
In: Technology
With the two storages, HDD’s are Hard Disk Drives meaning they have a magnetic platter with reading heads on multiple sides of it spinning at a few thousand or more RPM when they are on and capable of reading and writing to their storage. Usually shaped like an H where it reads on all four surfaces of the H minus the center axis, the horizonal line. SSD’s are Solid State Drives and a form of storage fairly similar to a memory card or SD card, there are zero moving parts within it, but SSD’s meant for computers have a lot better read and write speed than a simple SD card. Good HDD’s and SSD’s will actually have another form of memory similar to RAM called cache to help smooth out the gaps in read/write behavior.
GDDR on the other hand is a form of RAM that is utilized by your graphics processing unit and it is not exactly the same as the DDR you’d find plugged in next to your CPU or central processing unit, GPU’s and their memory are optimized to handle their niche workload better than the CPU and system RAM.
Basically the GPU is doing math with slightly different equations to handle what its working on better than the other processing units, and the GDDR RAM is tuned to be filled by this data particularly well. Also those equations let the GPU chip be clocked at higher speeds than an equal slab of silicon manufactured as a CPU could withstand safely.
