Building new Setup, interested in RAID, Help?

post #1 of 10
Thread Starter 
So I'm planning on building a new setup once Intel decides to throw the Sandy Bridge back up on the market. As of right now I'm thinking of picking up like a 64Gb SSD to install my OS and maybe 1-2 programs on then install all the rest of my programs on another HD. Since I want something fast, I've been considering doing a Raid setup with like 2 1TB drives or something, I'd still have another drive as just storage since I don't feel like clearing all the data on that drive and I don't have an extrernal.

Anyways, do I need any additional equipment to run a Raid setup? I've also been debating on whether I should do Raid0 or Raid1. From what I understand, the difference in performance between those two is just Write speed correct?

Thanks.

RAID 0 is striped data -- everything is split in half. Half of your data is written to each drive, theoretically doubling transfer speeds. RAID 1 is mirrored. Anything you do to one disc is automatically made to the second disk. If you're looking for increased speed/performance -- go RAID 0/striped. If you want data security -- go RAID 1/mirrored.

Other things to consider: If you RAID 1 two 1TB drives you'll still have 1TB of data. If you RAID 0 two 1TB drives you'll have 2TB of total drive space. Also, if you want to reduce access times and get closer to SSD performance, short stroke your RAID 0 array. Short stroking is the process of purposefully limiting a partition to 10-25% of the RAIDs total capacity, forcing data to be written on the outer edges of the disk where it spins faster. Combined with less head travel (because the rest of the disk is blank), the end result is faster speeds still and better access times because there is less space for the head to travel.

For a setup like yours, optimal short stroked capacity would be about ~200-300GB

Well, this is just for Programs and shiz, I'll end up using just a single drive for storage of important files and whatnot. So if I do a Raid0, I could go with some smaller drives right?

Any idea on what drive I could go with for Raid0? I'll be okay with like 500gb. Cheaper then better really, as long as it's still good.

Yeah. You have double the storage with a RAID 0 array because you're utilizing both disks.

Look at Seagate 7200.12s or Momentus XTs, Western Digital Caviar Blacks, or Samsung F3s

How much of a difference does Cache size and Sata 3.0 vs 6.0 make?

Cache size -- marginal. Depends on files sizes and such.

SATA II 3Gbps and SATA III 6Gbps -- do not spend the money on a SATA III hard disk. Nothing but marketing greed and wasted money. A traditional hard disk cannot max out SATA IIs 3Gbps transfer speeds. Why pay extra for something you can't use?

Well, I have these two drives in my computer already which will be wiped when I build my new rig. Can I just get throw these 2 together in a Raid0? Would it be better to buy one HDD to match another one those? Or just to buy 2 new HDDs?

Yeah, I've had those 2 for quite a few years, but they've treated me quite well, haha.

They don't have to match. You'll just lose whatever extra space the larger drive has as your smallest drive will be your limiting one. And even if they're not top of the line/fastest of the pack, you'll notice a healthy improvement in going from 1 disk to RAID 0.

So I guess in the end the HDD speed isn't gonna make a huge difference anyways right? At least nothing noticeable to the point where you'd want to flip out and throw your computer out the window?

No, not really. Just make sure both drives match speed wise. In your case the two drives do so you're fine.
