Ok, so i'm REALLY starting to look into this and quickly. Couple more questions for all of you:<br><br>Debating between going hardware raid 5 and just a bunch of non raid disks.<br><br>I'll start with the questions: <br>1) Can you convert from Raid 1 (Mirroring) to Raid 5 without loosing/moving the data?
<br>2) Can you add disks to a Raid 5 without having to move data off the Raid/Reconfigure the Raid (i.e. can you add the disk in place)<br>3) What Raid card would I want that is Fedora RedHat compatable (i'm not against another distribution, I just know RedHat like the back of my hand now) for HARDWARE raiding (software raid in Linux has caused me NO END of troubles)...IDE or SATA would be fine...SATA pref.
<br>4) If I go with simply a bunch of disks like mentioned above what kinds of SATA Cards would I want to go with? Anything to stay away from as far as support through Linux/Fedora?<br>5) For HDTV, should I be looking at Gigbit Ethernet to appropriately stream data over the network or can I get away with 100BT?
<br><br>Here's the thing, at this point i'm looking at one or two drives but being expandable in the future. I'd like to go with a pair of 250g now (potentially Mirrored) and add to that in the future to build up a raid 5...depending whether the wife feels like the data on the PVR is too good to replace or not.
<br><br>Obviously if the verdict is "Na, we can loose it" then i'll look at a non-raid solution since frankly raid 5 is just expensive and Mirroring is just stupid when you're talking about adding more disks in the future (have to add in pairs). Otherwise I need some kind of extendable solution...the epotomy of which would be starting with 2 drives now and adding a drive at a time in the future.

<br>and moved the 3.0Ghz CPU to my NAS box.<br><br>XvMC really lowers the CPU. If you run vlc with XvMC and it's<br>not available, you don't get video. You can verify it that way.<br>vlc is part of Video Lan Client<br><br>
I have a 6600GT with a fan. It runs hot even when it's not<br>doing any graphics. I'm thinking about swapping in some<br>non-fan'd video card to see if I can get good graphics<br>and reduce the heat / noise.<br><br>> As to the whole networked file system thing, what's this myth_archive_job.pl

<br>and it will find one with enough free space... and it makes a symbolic<br>link from the new location to /mnt/store and that's all it needs to do.<br><br>> I had always expected that I needed to have one huge LVM Partition mounted
