Need advice on which RAID configuration to use..

post #1 of 14
Thread Starter 
I just got 2 X 1 TB 7200 RPM HDD for $120 and I want to RAID Them and install windows on the RAID...

The problem is, I don't know which RAID configuration to use...

I want better performance, but I don't want to risk losing everything if one drive goes.....

Would RAID 1 be the best solution?

RAID 0 splits the data between drives (no redundancy)
RAID 1 mirrors data between drives (same data on both drives)

You want 1, given your requirements.
Keep in mind that you will only have 1 TB of usable space to work with.

That's fine as long as I get more performance & reduce the risk of data loss should one drive fail...

My next question is, how do I set up RAID 1? I have never done a RAID before..

I want to make sure I understand clearly the process before I move forward with the install, I have a 3rd drive for backup should one fail..

its as simple as setting the BIOS to AHCI and choose which drive you want and which RAID setting you want, stripe size, and boom you will be in business

Thank you Gerrardo, +Rep 4 both of ya.

Um the Stripe Size has me confused though... How will I know which Stripe Size to select?

1. Plug your drives in and boot into BIOS.

2. Enable RAID from your BIOS options(don't worry your SSD will remain in AHCI).

3. Reboot and hit your motherboard shortcut for getting into your controller BIOS.

4. Select new RAID 1 array and choose the two identical drives you have just bought.

5. Select a stripe size of about 128kb(this is for general use, post back if you will be using your computer for handling either very large files or very small ones, we could then change the stripe size accordingly).

6. Create the Array. Since you have Windows 7 already installed the drivers should be already on there and you shouldnt face a problem.

7. Go into Windows...you may have to format your drive(new drive of 1TB) for it to show up in windows and to be useful. (right click My Computer>manage>Disk management) . I think you can manage from then on.

8. Report back with HD tune results(run an error scan to see how the array is holding up).


Hope you found this helpful.


I quoted myself here. Note that this is the setting up of a RAID array AFTER the installation of Windows. Any other questions you have report back. Also, test the array as well using HD tune.


Also, if you could, i would recommend you buying 1 more drive and going into RAID 5. This would give you a performance boost as well as a redundancy.

I completely agree.
Ive always kind of seen RAID 1 as going halfway in both speed and data protection.
You will be quite a bit faster, and you will have real redundancy not just mirroring.

All I have is 3 Disc, but I cannot use one for RAID till I get the data off of it onto the 2 RAIDed Disc... is that possible?

BTW This will be a FRESH install of windows & will be storing files from 1-8 GB in size, sometimes more I think I have a 10 GB file somewhere (Game Module)...

RAID 5 requires 4 disc though, something I don't have, and do not want either, don't think my OC & Video card could handle running 4 drives on my 500 Watt Power Supply, it's running very warm now with one drive... (I took my SSD out for backup)

Not sure if your controller would let you but it's entirely possible to have 2 disks operating in RAID 5. The only caveat is that it would be a degraded array and if either disk were to fail you would still lose all of your data.

3. RAID 1+0 requires 4.

Ok, I got RAID 1 + Windows installed, and 1/4 of my software is installed...

I did a Disc Benchmark of the RAID 1 configured 2 X 1 TB 7200 RPM Seagate HDDs...




The error test came up clean...
