    I think NAS wouldn't be quite practical in my case.

    Umm..... The thing I concern is that I will be storing all the original data in External HDD and as the time goes my collection will be piling up.
    So should I buy 2 External HDD so that to back up each other just in case 1 HDD died so I still have a backup.
    I've heard about RAID before but I don't really understand how it works.

    TIA!
    There are a lot of different levels of RAID, more info here - http://en.wikipedia.org/wiki/RAID


    What you need is basically RAID 1, whereby the data is duplicated on both HDDs IDENTICALLY.

    no need to go with RAID.

    500 gig hard disk now about 160-170.

    hard disk storage case with E sata is about 70 bucks.

    Actually even if the items are cheap, it would be more practical to put 1 casing that can support multiple drives at home. or else you will find yourself in need of more power points.

    I think Raid 1 (mirror) is very good solution. No need to do manual copy as everything will be duplicated automatically.
    The other things (for windows users), if you park your data under your own folder profile (e.g. c:\document and setting\user\, nobody can access it except yourself. Not sure for mac though.

    For external HDD, if your PC has multiple user, other users can easily access your external drive. That means, no privacy or they may accidentally delete the data.

    Any advise would be greatly appreciated.
    Kevin's manual RAID solution:
    have two copies of important stuff on DIFFERENT HARDDISKS
    the key is different HARDDISK.

    you can have software type of synchro between folders.
    this way u max your HDD usage.
    I think RAID is overkill for most users.

    if you wanna up the secure level you should have it on different harddisks in DIFFERENT LOCATIONS.
    if both disks are on ur computer table and a fire breaks out. nothing can save one of them.

    I have difficulties detecting my colleagues' Freeagent and it uses two USB ports apparently, so its quite mafan.

    To me, the most cost effective external HDD is just buy a HDD, and a S$10 casing and viola, external HDD. Cheap and Good. And its much smaller than the freeagent.

    Note that some people encounter overheating with casing so nid well ventilation... imo jus get the adaptor wire can le, cheaper than the one wif the casing some more...

    heh i can answer that..
    the cable can connect sata pata 2.5 inch and 3.5 inch
    the casing.. well only 2.5 inch pata

    that's the difference in price.

    Set up a RAID DP (Redundant Array of Independent Disk Dual Parity)if you are feeling rich! But I am not sure if this RAID level is available for consumer right now. It supports up to 2 HDD Failure. Meaning, if 2 HDD fails, you can still plug in new HDD and recover information inside

    Just do a normal HDD back up will do. Whatever RAID you are on, it's just overkill.

    If possible get at least a decent Enterprise Edition HDD. Since your digital data is very important to you, choosing a realible working HDD like the Enterprise Editions will help you.

    I am using the Hitachi 1TB Enterprise Edition which is a fantastic way to back up all your data. You can partition half which is your permanent data one one drive and the other as a working drive.

    Overkill or not, depends on the individual... and how important the data is to them.
