Not quite. All cache is just blanket term of storing some data on faster storage and closer to usablity. Cache can be done at different levels and to different mediums.
L1 Cache is hardware-controlled cache for the registers.
L2 Cache is hardware-controlled cache for the L1 Cache.
L3 Cache is hardware-controlled cache for the L2 Cache.
RAM is a hardware-controlled cache for the CPU.
SuperFetch is an OS-controlled cache to RAM.
ReadyBoost is an OS-controlled cache to NAND on hybrid drives. These are HDDs with a SSD onboard (only 1 by Samsung existed).
Seagate Momentus XT is another type of hybrid drive but run its cache stategy onboard so the OS is not even aware. This is a hardware-controlled cache to NAND.
Intel Smart Response Technology is a driver-controlled cache to NAND.
Adaptec Hybrid RAID is another driver-controlled cache to NAND.Edited by DuckieHo - 5/27/11 at 8:31am
