    Raid controler

    Does anyone know very much abot Raid controllers I was just recently introduced to it so I was curious on exactly what people opinions are and whether or not it is worth it, and also whether or not it is better than getting a SCSI cotrol. hmm...I think that was a run on sentence. Oh well this isn't an english class so I'm not getting graded

    Re: Raid controler

    Worth it for what purpose would be my question. RAID has been around a long time and is a great solution for corporate needs - heavy duty ones anyway. I can't think of one single compelling reason to go to that expense in a home situation unless you have a wad of <img src=/S/money.gif border=0 alt=money width=17 height=15> burning a hole in your pocket.

    RAID, depending on the level (RAID 5 for example), offers varying levels of redundancy and data parity. It's intended to reduce the risk of data failure by making sure that the whole storage solution doesn't tank at once.

    SCSI is expensive too, add that to RAID and it gets out of hand very quickly. IDE RAID has become a cool thing to talk about on the overclocker's websites but it has no practical purpose for the average bloke.

    Well what would you say would be best for personal use, but also business use run from home. I won't have a network of computers for about 5 or 6 years yet, and no need to have it yet. Would you suggest SCSI at all for personal, and business use? I have the money to go either way I am just trying to decide what the best decisions are for my needs.

    I've never had need for anything other than two large IDE hard drives for home use - and that include business functions as well. One hard drive serves as the redundant unit - but only for data. I currently run the following (details left out for clarity) as a good, dependable way of saving my @#$!% if something goes south:

    HDD #1: 80GB Western Digital Ultra ATA 100, 7200 RPM
    HDD #2: 40GB Western Digital Ultra ATA 100, 7200 RPM
    CD-RW: For backing up things to CD periodically

    I have a manually initiated backup to the second hard drive, which includes data only. I toast these onto CD once a month or so. In addition, I dual-boot Windows XP, one configuration being bare with nothing installed except for hardware drivers. In a pinch I can boot to that copy of XP with no known problems and do surgery if I need to, or worst case restore a working backup to it.

    I don't see any cost advantage in using SCSI, current IDE implementations are just as fast and a helluvalot cheaper. It wasn't always that way, but it is now. The only real advantage to SCSI drives - and it can also be a problem because of the heat - is that you can get them in faster RPMs than IDE (10,000 I think is the current limit). Will that make a difference to you for the money? Doubtful, and even more so that you would notice any benefits for very long.....right about the time you got hungry and your wallet was thin, you'd be telling yourself "I'm hungry, but man is this computer fast...." <img src=/S/grin.gif border=0 alt=grin width=15 height=15>

    Re: Raid controler

    hehe...Well like I said I can afford either without worrying about going hungry (at least for the day or so) <img src=/S/grin.gif border=0 alt=grin width=15 height=15>. Anyway the advice on the hard drives are great. But what about SCSI CD-RW's? Are they worth the extra money? I burn CD's everyday and so it would get a lot of use out of it. I burn things from just regular music, to back-up files. Again I do appreciate the input your giving me, it is helping me out a lot when I am deciding how i am going to have it built.

    Re: Raid controler

    I don't see any advantage....again, you're getting nearly identical performance for less money. One advantage to SCSI is that you can have more devices on one chain, but I think with the advent of fast IDE, FireWire and USB 2, SCSI is just an aging dinosaur that isn't going to be a viable choice.

    Chaining SCSI devices can also be a problem, because of termination and compatibility - add a slower SCSI device to the chain and you lose all the benefits of the faster (I.e. Ultra Wide) iterations.

    Re: Raid controler

    Again I thank you for all your input. I have figured with what I originally thought I was going to get with SCSI devices, but subtracting those I save myself about 1000 dollars right off and I can use that for a better use. Glad I decided to make a post and get the suggestions from people that know a lot more about certain hardware than I do.
