Seagate came out with a 500gb hdd that has a 32mb cache. How important is cache size? Will it make much of a difference in speed? Would it be more important to have the 32mb cache size on my os hdd or as my video, pics etc. hard drives? Please let me know what you understand about cache size on hdd because I don't for sure.
the cache is the buffer memory between the controller and the mechanical hdd. the more cache it has - the more data it can store to transmit off to the controller, the faster data access on the hdd will be.
it's basically the size of the chunk of data that the hdd can send off to be processed at a time
