The Buffalo LinkStation 220 runs a dual-core ARM Cortex-A15 at 1.4 GHz

Buffalo’s LinkStation 220 is built around an ARM Cortex-A15 — a dual-core chip running at 1.4 GHz. That’s not going to break any speed records, but for a NAS appliance handling file serving and backups, it’s enough. ARM chips keep the power draw low and the noise down, which is exactly what you want from a 2-bay NAS sitting on a desk.
