RAID Partitioned Drive

And I'm assuming hardware raid is better than software right?

It has advantages and disadvantages. The benefits of hardware RAID tend to be pretty specific, and only come when you're spending a lot of money on a good card. 

 

Between Software RAID and cheap Hardware RAID, you'll actually be better going with Software RAID from a performance standpoint, and it won't offer any of the advantages that more expensive hardware RAID does. You can go with Intel's in-built RAID controller, but it has the same issue as hardware RAID, where it just sees the drives as a whole. (I would advise the on-board RAID controller over a cheap dedicated card). 

 

Higher end RAID cards have a power-loss protected cache, as well as support for a large variety of complicated RAIDs, as well as often having notifications for when a drive fails on the array. 

 

Basically, dedicated hardware RAID is not really a consumer need, as the good quality ones are very expensive (especially not worth it for a simple RAID 1 setup, which can be handled on-board or through software).

In my PC I have a 1TB drive, and a 2TB drive. Is it possible for me to make 2 1TB partitions on the 2TB HDD, and then raid one of the partitions with the 1TB drive?

 

Is it even worth doing? I'm looking for a RAID 1.

 

Is it worth spending the effort to rip a 1TB out of an enclosure I have and just raid 2x 1TB?

That's all you need to know. It's a beast.

that would not help because both partitions are on the same drive...

 

raid 0 takes advantage of having the speed doubled by two drives working at the same time

I think you aren't understanding. I want to RAID 1 a 1TB drive, with a 1TB partition on another 2TB drive.

He's looking to basically have a 1TB drive in RAID 1 with a 1TB partition of a 2TB drive, with the other TB separate. The two Partitions for RAID 1 are on different drives. 

 

@OP It's possible with Windows RAID, but tends not to work with hardware RAID , as it just sees the drives a whole and not partitions.

oh i see what you're trying to do

 

no, the raid will use the entire 2TB disk and you effectively will only have 1TB of usable space

Yeah, I replied before the thread updated. 

 

Should be possible through Windows RAID though.

I can swap the 2TB for a 1TB I have in an enclosure and just use hardware RAID with the onboard RAID controller. I'll probably do that instead of messing with partitions.

Hey there AverageHardware :)
 
It should be easy to pull through the Disk Management option. You should have both the 1TB and the 2TB drives as unallocated and then simply select the New Mirrored Volume, including both drives. The second half of the 2TB drive should remain as unallocated which you can then configure as another separate volume. Do have in mind that the process formats both drives and any info from them is deleted. :)
I wouldn't recommend it, though. I would use two NAS/RAID-class drives for this with the same capacity and model just to minimize the risk of a drive dropping out of the RAID. WD Red should be a good choice for that: http://products.wdc.com/support/kb.ashx?id=zBRq16 :)
