Is there a noticeable difference if you had to raid 2 x 500GB WD caviar black hard drives in either 0 or 0+1? Is it worth the money to purchase another hard drive as currently i have 500GB WD caviar black, and it scores 5.9 in windows index.
 
RAID 0+1 requires a minimum of 4 drives.

RAID 0 should give you a maximum of 100% increased read/write speed.
It is very important to note that if you lose 1 drive when you're using RAID 0, that you'll lose ALL your data.

Here's a Wiki page on RAID: http://en.wikipedia.org/wiki/RAID

I can't comment on whether it is worth it to go for RAID in a normal desktop PC.
I would rather recommend going for a 60GB+ SSD :)
 
SSD's are so expensive, and with all the games i have loaded....i dont think that 60GB will even come close to my requirements. Im not too worried about losing data, as all my documents etc are backed up on externals, and besides....with the latest technology....What is the odds of your hard drive crashing?
 
RAID 0+1 requires a minimum of 4 drives................. NO>>>>>>>>>>>> requires 2 disks....

Raid 6 requires 4 disks....

The chances are extremely good, you HDD can crash any moment, be paranoid about your data at all times....
 
The odds of raid 0 crashing are the same as the odds of any hdd failing.

Bare in mind when you raid 0 2 drives you effectively have one drive, should something fail the entire array is gone. Go for raid dude, it is very nice.
 
A Raid 0 wont increase your write speed all that much because it still needs to write that data on the two drives. Read speeds are significantly higher especially with multiple users accessing the drive.

Games load faster, windows runs faster.

I have tested this. It makes a big difference.

Incorrect - whether you are striping a mirror or mirroring a stripe, you need to double up on the amount of disks. Minimum disks in a mirror = 2. Minimum disks in a stripe = 2. Add em up... You need atleast 4.

+1, as long as it makes windows, games etc run faster then im happy. How big of a difference did you see when you raid in 0?

Edit: if i get another hard drive, then can i just set it in to raid in the bios and start as normal, or wuld i have to reformat? If the need arises to reformat, cant i use this software to make a clone of the hard drive, then change it to raid 0 in the bios and run as normal,

I haven't used a RAID system yet for myself, but the time when I setup RAID 1 for a friend of mine, it had to reformat both drives!

oh really? :)

(see signature..)
 
So cut a long story short, if you not worried about hdd failure, then is the price worth the performance difference.

I currently score 5.9 in the windows index score chart, so what would I be looking at with raid ( just to get an idea)
 
Why dont you buy 3 HDD drives ?
Raid 0 2 of them and have the 3rd one for important backups like files, photo's ect ect.
 
I don't need internal backups as I have several externals and I only use my new pc for gaming as I use my laptop for working.
 
I'd say go for it dude....
The last time I did a RAID 0 was 8 years ago when 40GB HDD's were the biggest you could find (I think there was 80GB's for those who had LOADS of cash to burn :))
Those days the average read speed was about 40MB/s... after RAID I remember getting anything from 65-80MB/s and it did make a noticeable difference.

Just remember to take a deep breath and pronounce it "Raaayyyyeed" when you tell people about your system, that way you'll earn the maximum cool factor amongst fellow geeks... :D

Ok, so far I know Intel have some set-up on some of thier newer mobo's where you can use 2 drives to make a raid 0+1.
Basically it uses 50% of each drive to make a mirror and then stripe the two.
Generally a raid 0+1 with 4 drives is the cheapest and moderately safe.
Raid5 would be more expencive, but mostly this is done via software and would be slower than raid0+1, also more expencive.

If you going the raid way for a boot drive, it can become messy on XP and Vista, as you would need a flipping stiffy for the drivers.
Also you would have to re-format all the drives in a raid.

This is a good point. As long as you're running a RAID controller and Windows 7 or Vista that has built in driver support for the controller, or you're comfortable in figuring out how to integrate a RAD controller driver into a Windows XP or later installation you shouldn't have problems. Point is, MAKE SURE you have everything you need before wiping your system (Installation disks, drivers, bootable flash drives etc. etc.) or I can promise you you'll soon be looking for troubleshooting solutions on this forum with the help of a mate's PC :)

I've been down that road... I'll always miss my 9GB's of BangBus porn I once lost when my RAID failed. :eek:
