>Quantum? What about a Fireball Pro[tm] with 256k or 512k cache? Well, as long as there's no reason to increase the RAM size why should we? BTW, "cache" is misleading. You'll never get any decent hit rates from anything less than a few Megabytes. It is a multi(or rather semi?)line track buffer. When you're running a few MB's worth of SMARTDRV or other cache any smaller amount of drive cache is useless. So it's just track buffering with read ahead and write back.
