I would love to get my hands on a WareMax HybridCache - it's a transparent SSD cache for a SATA hard drive. It goes between the hard drive and the Tivo: http://vr-zone.com/articles/waremax-does-platform-and-os-independent-ssd-caching/12554.html It looks like it's the closest thing to the old cache card from the Series 1 Tivo's. Talking more about it here: http://www.tivocommunity.com/tivo-vb/showthread.php?t=454580&highlight=cache&page=2 Look towards the bottom of page 2... Anyway, in all the googling, all I see for apparent end users having this product are forums in what I can only assume is Chinese - since I'm only an English speaker. Apparently they did ship in Taiwan, but I haven't seen any mention/sighting of them outside of Taiwan. Probably squished by a patent or some other BS If anyone can read the forums - are there any clues as to what happened to it? Or even cost - if it was more than a couple hundred bucks I wouldn't bother. But I suspect they were shooting for under $100.
