Hello, I have a SATA3 SSD with OS and Apps on them, and 2 SATA2 HDDs, one for footages/projects and the other for renders/archive.
I believe putting the disk/media cache in the SSD would boost performance because of the speed, but I heard it can shorten the lifespan of the disk, although I'm not sure by how much.
I guess I could purchase another SSD dedicated for disk cache, but I'd rather not if putting them on the same drive with OS and Apps won't be too much problem.
