Advertisements Hi forum, I just got my new Tivo HD up and running. I obviously need to expand the storage a bit. I was a little surprised in reading the FAQ about how much importance was placed on "AV" drives. I understand the differences, but I've upgraded a number of TiVos over the past years (series2, multiple DirecTiVos), and never used anything but normal drives. The AV drives seem to carry a pretty significant price premium (I can get normal SATA 750GB for $150 shipped, or 1TB for $175 shipped - these are Seagate or WD drives), and it seems to me like the extra price might not be worth it. Are there any differences with SATA drives and AV vs. normal, as compared with the older IDE/PATA drives (all my older upgrades were pre-SATA)? I'm having a hard time convincing myself to spend the extra $$$... Also, it seems like it may make more sense if I'm going for 160GB -> 1TB to just upgrade the internal drive, as opposed to adding eSATA. I already have to pull the drive to marry the two together, so at that point it seems like it's not worth the extra enclosure cost to have 160GB + 1TB as opposed to just 1TB internal (and put the 160GB on the shelf). Am I missing anything here?
