Western Digital My DVR Expander (500GB, eSATA Edition)

Pros: Easy to attach and configure; multiplies your available DVR storage capacity; compact wall wart eliminates separate power brick

Cons: You can only attach one to your DVR; cannot later be used as an external drive on your computer

Summary: This device is the easiest way to add significant storage capacity to your Scientific Atlanta DVR, TiVo Series 3 or TiVo HD. For just over $200, you can increase your TiVo's storage capacity to nearly 1000 hours (or just under 100 hours of HD programming). Wow! Note to potential customers: If you can't find this stocked near your local retailer's TiVo units, check in the computer section with the other external hard drives.
