| Post subject: | Running System From A Flash Drive |
My interests include low power HTPCs: if the system would run without a spinning HDD (either boot from IDE Flash Drive or USB stick) that would significantly reduce power consumption (and heat). That being said, this memory is $$$ and one would still want a HDD for movie storage. Is there a way (support for) idling a spinning HDD when the system is idle? or is this idea just not possible for some reason or another? |

Booting from a flash drive might make sense for a dedicated frontend (think "display server"). You can also boot off a LAN connection if your bios supports it. I've read that some people have had support with low power Via processers, and other's have taken high-end processors and under-clocked them to bring down power usage. If the box is going to have a HDD, I know I've read that you can set it up the system to "wake itself up" to do a recording. Your PC can then be turned off when you're not using it. Again I think you need bios support for this. I don't know about idling the hard drive. But the nature of this system requires mass storage AND lots of read/writes. Remember there's a lot of SQL and log writing going on. At this time that means having a hard drive on, at least somewhere, when you're doing almost anything with mythtv . |

Mogator88, good idea. I could limit the scope to a front end device to be a player only: it could have an extremely small form factor. If it were to boot from a flash disk, this front end would really become more of an appliance. I hope that other senior members of the forum will comment. |

This has been discussed before. I thought about building a Via system myself. Do a search here on Via and mini-itx and you'll learn all about it. Regarding the flash drive, if this is a dedicated myth machine I'd try booting off the network before a flash drive. The flash drive is another layer of expense and complication. They're not designed for the heavy r/w activity of sql, paging and log files, so you're dealing with network "issues" anyways. A USB stick hanging off a case is rather flimsy and accident prone, too. You could probably use a laptop hard drive with the Via processor, and get a full featured lower power computer. Or you could buy a used MediaMVP and get a good bit of the mythtv functionality in a low power diskless device. |
