    Which is exactly what Dave Zatz's update says that got us on the subject of the 2.5 drives.

    I think that's the plan. The 4 tuner unit would be a smaller form factor box while the 6 tuner would be similar in size to the current Premiere units.

    Although the drive would need to support more then 5 streams. In addition to recording 4 and playing back 1 locally it also needs to support playback to 3 external devices such as a Mini or Stream and one each, incoming and outgoing, MRV streams. So 9 total streams. Or at least that's what the current units do. And the 6 tuner will need to support at least 11.

    Although TiVo supports a max bitrate of 25Mbps, which is only 3.125MB per second, andost hard drives can handle a sustained read/write speed of at least 50MB per second so it shouldn't be a problem at all.

    Oops, missed that Zatz nugget.

    Native WiFi on the box will be good, so long as TiVo doesn't get stupidly cheap and not have 11n capability and WiFi Protected Setup. Fewer wires is good, and I have a (possibly irrational) dislike of MOCA (vs 1G Ethernet).

    It could be. First of all, 50 MBps reads are no problem, but writes are another matter. I rarely see sustained 50 MBps writes to a single spindle on consumer quality drives. Secondly, 28+ MBps is getting a little close for comfort to the 50 MBps hypothetical for real-time transfers. Thirdly, the sustained throughput is not the most important metric, here. It is the number of IOPS and the random seek rate that rear their ugly heads when talking about multiple simultaneous reads and writes.

    :eek::eek:

    Only five simultaneous HD video streams?? That seems rather low? I've used 2.5 inch drives in the past that could handle reading/writing more HD streams than that.

    What kind of drives are you using? The single platter 1TB drives have zero issues sustaining 100MB/s write speeds.

    That's the official specification. Not only that, the spec says "five playback streams". Presumably the official number of supported recording streams is even lower.

    The current gen units do it just fine and they are using 5400 RPM drives. I can't imagine that a 2.5" drive would be any slower. In fact it would probably be slightly faster since it probably only has 1 platter instead of two.

    I'm betting the Wifi will only be supported for the internet leg of the connection and you'll have to use MoCa or Ethernet for streaming. I think the intended setup will be a single TiVo in your main room, either 4 or 6 tuners, with Minis spread around the house for viewing in other rooms. The Minis will connect to the TiVo via MoCa or Ethernet and then the TiVo will bridge that connection to WiFi for internet access.

    They could accomplish this pretty easily by simply blocking the UDP discovery protocol on the WiFi leg of the network. If the TiVo's can't see each other via WiFi then you wont be able to use it for streaming. Even 802.11n is not fast enough to support the 3 simultaneous streams that are possible with a TiVo.

    It's also possible that the WiFi could be used as a bridge in the other direction allowing a device like an iPad connect to the TiVo to get on the local network. This might be good for people with wired networks that want to use the built in Stream capabilities it's rumored to have.

    The 3.5 AV-GP is rated for 12 streams over 5 for the 2.5 drive. It has a smaller buffer also not sure if that matters any.

    I don't need any more tuners or storage space. what I need is a better interface. Quicker, better app integration, and full HD. Get rid of this flash crap.

    Flash isn't going anywhere - that I guarantee. But the new boxes are supposed to have a more powerful processor that handles the load of the UI better (the Mini is an example of this upgrade)

    If TiVo releases a 4 TB capacity TiVo Series 5 with six tuners, I'm in on buying one! :D

    Because they have invested a huge amount of resources and time into the current architecture.

    There isn't anything particularly wrong with flash (adobe air) as a platform, but as with any tech, if the processor isn't up to the task the the user experience will suffer.

    Others more knowledgable them me have reported that the Current Premier processor in the Series 4 doesn't meet the minimum specifications for Flash.

    The current processor just simply isn't up to the task.

    It is always a balancing act trying to navigate price, power consumption and performance in a consumer electronic.

    Actually, I am not sure about the drive size, but I do expect that they have extended the size limitation cap of the current units. Current max is 2 TB, so I expect to see at least 3 TB option. Hopefully upgradable to 4

    I doubt it would be 4TBs. It will more than likely be 3TB. The 3TB drives cost around the same as the 2TB did when they released the Elite. WD makes a 3TB drive in the same line that TiVo has used in the past but not a 4TB drive yet.

    Even if it's limited to 3 TB, that's still 471 maximum hours in HD recording. I'll take it! :D

    I would prefer 4TB but 3TB will do. Plus 4TB drives are too expensive still. There is no way though that I would get a six tuner box with only 2TB of storage. It would not be enough storage for me. Or I'd have to start using TiVo Desktop more often again.
    I haven't used TiVo Desktop very much since getting two of the 2TB Elite TiVos.

    Sources tells me we're looking at 1TB and 3TB options in the 6-tuner model.
