How much does HDD cache matter with Linux softraid?
- by Jawa
I'm in a process of renewing/expanding my disk sets, but not quite sure what kind of disks to get, cache-wise.
What difference does disk cache amount of 16/32/64MB do, in capacities of, say, 1/1.5/2TB SATA disks? The disks will be used in a webapp server and in a media workstation, with Linux's softraid in raid-1/raid-5 configurations. Note, that as both purposes are purely for a hobby, the pricetag for a dozen of disks is a big issue.
