Raid info

[dynasty]

I currently have a WD 80gb Special Edition. And I want to buy a raptor and use that as the hard drive for windows/games/software. I have some saved folders on the 80gig, movies, music, software, etc, that I want to use for just that hard drive. Is there a way to setup a raid with the two hard drives without erasing all of the saved folders on the 80gb? Because I don't have another computer to save those folders to.

I"m not sure exactly what you're trying to do, but I'm almost positive RAID isn't what you want. You want the raptor to run the os and games and you want to back up your documents and things from the 80 gig to the raptor once you have it installed, then use the 80 gig as a storage drive, correct?

If that's the case, just install the raptor, install windows, then install the 80 gig drive on another channel or controller (make sure your bios is set to boot from the raptor first) and copy over the files you want.

Yeah I wouldn't mix the two drives in a RAID setup. I think Brian is right about your intentions. Raptor=boot drive, WD=data drive.

Raiding a sata drive and an ide drive. HMMM. Didn't know you could do that. Wouldn't the different seek times and speeds cause tremendous headaches?

I don't think those two drives could raid together. Just my guess but I doubt you could raid pata and sata drives mixed.

Said it before, will say it again, RAID requires two "identical" drives. At the very least they have to have the same capacity. The largest raptor has a 74GB capacity, which is clearly not the same as your 80 gig ide drive.

Second, there is no raid controller that I know of that can run a Sata drive and an IDE drive in a RAID array. Its either 2 satas or 2 ide's.

3rd, its been positively shown on anandtech that running RAID 0 array provides no real world perfomance increases. If you want to get two raptors great, they are awesome drives, but use em both separately or in a mirroing configuration. Otherwise you are wasting a smokin fast hard drive for no reason

While I think the OP was just confused with terminology, and basic slave/master/channel harddrive concepts, not everything you mentioned is true. Raid arrays can be created with different drives. It will just be bottlenecked by the drive with the lower speed. The amount of data stored will also be two times the size of the smaller drive, and the extra space on the larger drive will not be used in the array.

Promise makes the SATA150 TX2 which supports both ide and sata ports, all drives of which are available in a raid array. Since bridge chips are used in a decent amount of add in raid cards(like highpoint), there really isnt an interface restriction when it comes to creating raid arrays. Plus you can software raid any drive on any interface.
