While the TiVo Roamio line may officially max out at 3TB of recording capacity, licensed reseller WeaKnees has offered 4TB drives nearly since launch. And, should that 637 hours of HD content not be enough, WeaKnees has just unveiled 6TB drives – a TiVo upgrade good for a whopping 960 hours of high def content. The WeaKnees 6TB DIY kits clock in at $450 while preconfigured 6TB Roamios start at $700… which is a far more practical solution for most than the ridiculous $5000 TiVo Mega.
