    right i have 2 questions

    1, i was wondering whats the difference between RAID 0 and RAID 1 is their some peformance increase or something

    2, if i got a bluray drice would i be able to watch filem on a 1900 x 1200 screen and would it be in High Def? or would it be like HD ready quality

    new question

    3, whats the difference between full HD and HD ready?
    would would a laptop with 1900 x 1200 res be?

    1) Raid 0 is two drives striped yielding a large increase in both write and read speeds, but at the same time doubling the chance of a failure as if ONE drive fails BOTH of the drives will be useless as all the data is split between the drives, so data security is very low on raid 0 setups

    Raid 1 is Mirrored and you cut your harddrive capacity in ½, as basically you would have 1 drive with the actual data on it, and then another drive which is a copy of the first drive. so if you have 2x200GB you only get to use 200GB using Raid 1. On the other hand your data is quite safe, as if one disk fails you have a copy which can be used to rebuild a new drive.

    2) High definition on a blu-ray drive is 1080p which is 1920x1080, so yes it would be in full quality. But for something to be HD-ready is has to be able to display either 720p/1080i/1080p so HD-ready is acutally High Def, just to clarify things a bit.

    EDIT: In my opinion don't even bother with raid unless your doing movie editing (Serious, not just once or twice a year) or something which requires you to move large amounts of data around often (like having a scratch disk for editing). In everything else the performance gain is negligible

    Re: RAID, it's really designed for servers, only serious home nethusiasts have raid and even then very few gain real benefit from it.

    RAID (above 0) isn't about performance gains; it's about data protection. That you get increased speed from some implementations is (IMO) a bonus but it isn't the raison d'`etre.

    A couple of other points to make:

    "HD Ready" is really used for displays; and it indicates that a display can accept an HD signal from a source. HD included is usually the term when the OTA HD tuner is included on the display.

    "Full HD" is a marketing term indicating a 1080p display.

    One thing to be careful of with your laptop is that playing back both Blu-ray and HD-DVD require HDCP for full resolution output and I'm not 100% sure that the laptop display qualifies.

    Cheers,
