Raid?

wok951 · 07-06-2008, 09:12 AM

I have been looking and i saw this thing called raid. It says you can have two hard drives and connect them to be one. Does anyone know how to do that. Thank you.

What drives are you wanting to RAID? Makes and models help. There are different types of RAID setup, for different uses.
For example...
RAID 0-To speed up disk access across multiple disks aggregated as a single storage device
RAID 1-All data is duplicated on a second disk, if one fails the system carries on as normal
RAID 5-Similar to RAID 0, but with extra 'parity' information inbetween, this information is used to recompile the data if one disk fails. Downside is you need 3 disks for 2 disks worth of data most of the time.

The two drives i have are western digital one is a 40 gb and the other 60 gb. The model number for the 40 gb is - WD400BB-75AUA1. The model number for the 60 gb is WD600BB-00CAA1. Now i don't know what setup i want. I want the two combined to become a 100 gb. Is there a way to do that? Thank You

You need 2 indentical drives in order to make them into a RAID 1. It is becoz one drive works and the same is replicated onto the other drive. It does NOT work with 2 drives of different capacities.

You cannot configure a RAID 5 on 2 drives.

and

For now, all you can do is configure them on RAID 0 which is basically add up all of the drives for the total of 100GB in your case.

The drives you have are of IDE interface and I havent done much with IDE interface. But I am sure someone here will be able to help you configure RAID on an IDE.

All I know is how to configure it on SATA interface.

Good luck.

Thanks Rockstat. Thank you for the info. Would you know anyone that could set up the raid 0 or will i have to wait for someone to reply. Thanks again for that information I am still new at this.

This will help you setup a RAID0 setup inside Windows. A full RAID0 that includes your OS has to be done at the hardware level (independant RAID controller).
You can just go into disk management through the My Computer context menu (manage, manage disks) and make the two into one dynamic spanned volume, which is not only simpler, but it will also show up in My Computer as one disk which is what you said you wanted.

Ok i tried what you said. But apparantly i need XP pro. Is there a way to do it in windows XP home edition?

**stressfreesoul** · 07-08-2008, 04:21 AM

You should be able to if you buy a hardware RAID controller. eBay do them for no more than £15 (US$30). They are usually PCI slot and sometimes come bundled with bonus SATA/eSATA/USB ports too.

There is another way if you buy a motherboard that has a IDE/RAID controller "onboard" Like the gigabyte GA-8i945P-G. It has a hardware type of RAID that does the work independant of the CPU. Unlike other software RAID controllers(that use the CPU power). I think "Promise" (the company) has highly recommended controllers from what Ive heard. But they are pricey. This is a add on card too.
And you are right XP home does not support dynamic disks, however it may allow a controller to if it has the software I think like Stressfreesoul said.
I am running a RAID 0 setup with an onboard controller.
See Ya

You should be advised that in the event of disk failure, you will lose data on both parts of the RAID 0 array. RAID 0 is not a suitable solution for a system drive and for crucial data. It's a great solution for temporary data, which is why we use it a lot in gaming and video editing.

**stressfreesoul** · 07-24-2008, 02:20 AM

Agreed, RAID 0+1 is better for recoverability, but then you need twice as many drives for backup.....just something to think about.

Yes WiseLeo I am aware of the various pitfalls of a RAID 0 environment. I have added backup options on an external MyBook Home and on my other Compaq with a Sil 0860 ATA controller with ATA drive. An Yes I am a Gamer at heart too. In General, I would only recommend RAID setups to people with lots of patience and tech savy. Also the bus speeds of an Intel RAID array are faster than any add on PCI controller thanks to clintfans long winded post in another thread on a similar subject. Thanks Stressfree for the input as well .... more drives means more money. I would be using a SATA controller from intel but one of the ports burned out so I disabled it in the BIOS(NO heat sink on the south bridge chip wow). Then I switched to the IT89212 ATA RAID controller due to the speed boost over regular IDE drives. Now if I can just get SANDRA to detect DMA speeds I will be just peachy(she says PIO mode is speed - error I think).
HD TACH 3.0.4.0 is reporting 72.6MB/s average read,FYI. Also I do have a post going for those of you who think I am hijacking this thread.

its called " 8i945P-G drives in PIO mode " Good night
