you don't need to have a RAID set up, it's additional features you're able to do when you have two HD's of the identical model. RAID 0 isn't true RAID and it strips files into pieces and puts part of the file on one of the HD's and the other part on the other HD. RAID 1 is where the second drive is an exact mirror of your first drive. there is additional set up needed for RAID other than just plugging in a new HD but again, it's not required for hard drives to be in any RAID array.

Well, if you want speed and performance, than it's recommended that you go for RAID 0. Just to let you know, there's no redundancy with RAID 0; that's where RAID 1 comes into play. It makes an exact copy of the other hard drive incase it fails, then you have another with all of your data on it. If they both fail, than yours**t out of luck. Personally, I think RAID 1 is useless as it's like only having one drive already.

But very usefull if you have data that's constantly changing and you need an imediate backup incase of hard drive failure!

You can raid 0+1 for ultimate performance and backup.. but then your looking at 4 drives.

I think RAID 0 is pointless. As a matter of fact, I think all the RAID array's are pointless. Just bragging rights IMO.

I don't think I could disagree more strongly with this statement. RAID 1 and/or RAID 5/6 are pretty well indispensable to any person or company who is serious about keeping data online and accessible, and RAID 0 is, as the previous post mentioned, pretty well indispensable to anyone who cares about disk throughput.

Edit - I forgot to disagree with this too :) I've been saved once this year by having my storage disks in RAID1 configuration. When a drive fails, rather than being totally shut down until you get ahold of a new disk, then having to restore from backups, etc, you just keep marching along. Get a new disk, rebuild the array, and all is happy. For less than a hundred bucks, this is probably the best possible use of my money when it comes to computer parts. YMMV, of course....

Edit again - Martin, here's a very thorough explanation of RAID as well as the various RAID levels (including some of the very esoteric ones)

if i want to use raid 1 like ya all say it mainly 2 hd mirror and i do want a hd to be a back up if my other one fails but how do i make it raid 1?

>> Re: Raid 0? raid 1?

first off:
, if you're dealing with SATA drives, you need to enter bios and make sure that your sata controller isn't set to emulated p-ata, it should be set to sata raid.. on reboot windows should install drivers if it was set to -pata.

the best way to do it (the way i like to do it):
second, have your raid contoller drivers on floppy, then back up all your info on dvd/cd ... then shut down your machine plug in the second drive, after POST enter Raid bios, and assign a mirrored (raid1) array to the two drives, shuld wipe the drives when you do it.
then re-install windows, (this is where you need the drivers on floppy. push F6, etc).. .

less hassle way:
if you dont want to re-install everything, then use Symantec Ghost, or Acronis True Image to back-up replica's of your dives on bootable cd/dvd. then make the array, and restore the single drive onto it.

Try capturing HD video on a single regular HDD, any HDD or any spindle speed. I guess Raid 0 is as bragging rights as much as a Core 2 Duo is for bragging rights. All fast hardware is bragging rights. That's right. You don't need to buy any faster hardware than a Pentium II 300 Mhz to surf the internet and do office work.

Media content producers break their backs and bank accounts to attain that magical 800 Mb/sec Firewire 2 bandwidth. Why? To show off and brag. OK.

Why Raid 1 is not fail safe. Your data borks on one HDD, guess what is written to the other HDD? That's right. Borked data. You have two drives, healthy or not, that can't get you into Windows anyway.

You guys like to use that crappy ass sata controllers on the motherboard. Its free. That's about the only good thing I can say about it. Mobo borks. Guess what happens to your data. Huh?

Why all Raids are not fail safe. Lightning comes along. Cry me a river! Enough said. That is why there is no substitute for external backup and Ghost.

I myself like Raid 50 and I'm moving to Raid 60 soon.

.OK., what kind of hard drives are you using? sata or ide?

what's that, striped dual parity? 8)
.. what the hell do you need that for? are you expecting 2,3 or 4 drives to fail simaltaniously?.. i guess im just jealous of your level of redundencey ;)

Raid 0 for performance. Raid 1 is a waist of time & HD space.

lmao, yeah, about as useless as a spare key to your car, or dental insurance...

so a young bull and an old bull are standing on the top of a hill, looking down at a pasture full of cows...
the young bull turns to the old bull and says "lets run down there and f**k a few of those pretty lady cows"..
the old bull looks at the young bull and says "listen kid, you're an idiot".. "you stay here, i'm gonna WALK down there and f**k 'em ALL! "

.. super.. don't be a young bull ;)

Let's see what you tolerance is for Russian Roulette.. 2 TB of data.. you want to risk that on a Raid 0 ? Like I said, if you understand the concept of load distribution, you will do second dimension raid, and 50 or 60 is at the top of the game. If you are into safety and speed, a 100 would be great. For speed, Raid 0 is useless when compared to Raid 00 lol :)

Phil,

The older I get, the more redundant I get lol :) You got to speak to me about a SAS setup. I'll hook you up and liberate you off a few grand lol :)

Well, I don't see anything wrong in using the controller that comes with your motherboard. Obviously there are better solutions out there, but at a prettier cost. Besides, not everyone has the budget to go off and buy like 15 hard drives to put into some massive RAID array - even though they'd like to.

i've actually got a SAS card around here somewhere pretty sure it's an adaptec 480.. or something .. 256mb, pci-x.. something on th order of $750 i think..

i had a few drives too, but i traded them for a motherboard and some very specail memory before i really got into setting up SAS... i know i've got use for serial attached scsi but dont have the brain cells available to do it :)

assuming your BIOS settings are all correct and you have raid enabled, then after POST you should see a raid bios screen.. and "push ctrl-A" OR something to enter setup... then assign your two drives to a raid1 array.. it's that simple.. the process will erase all the data on the drives however.. so you will either need to re-install everything, or GHOST your drive beforehand.

If your motherboard directly supports RAID, then there should be a chapter with step by step instructions on how to set up the different types of RAID, and which chipset to use. As different BIOSs and Chipsets have different proceedures, getting the instructions for your specific MB is your best bet here. If you didn't get a hard copy manual, it is usually included on the support CD or is available for download from the MB Manufacturers site.
GOTCHYA ALERT!!!
If you've never had a RAID on the system, it may be necessary for you to build a driver installation diskette that will be needed during the "blue screen" portion of the OS install. You will be prompted to press "F6" to add drivers and you will have to have a diskette drive available to put the diskette into....In this day and age MS still doesn't support loading these type of drivers off of a support CD (though a custom build CD with a modified setup.ini and the drivers present is possible, this option requires some advanced knowledge).

I have an ASUS board that has the NVidia RAID as well as SiL RAID. I don't know if it's just me, but I've experienced slow throughput and stability issues with the SiL chipset, but the NV RAID has been stable in both RAID 0 and 1 configurations.
