36gig Raptors in Raid 0

I know its late, but you really should have went with a single 150Gig Raptor rather than the 2x74GB ones in raid 0, there has been plenty of tests that proved a RAID0 setup, offers almost nothing for games/desktop performance. Taken from a post on Hardocp (there has been plenty of others) shows that RAID0 shortcommings are

A) Reduced reliability
B) Increased heat/power draw/noise
C) Increased system complexity
D) Greatly complicated backup and disaster recovery
E) Substantially increased cost

Heres also a graph of 2x74GB raptors and 4x74GB raptors, vs the 150GB raptor, taken from storagereview.com

I/O's per second don't give any indication of read or write MB/s though, and this is where it counts.
 
Ive seen a pair of IRAMs in a RAID0 configuration and that only loaded farcry 2-3seconds faster than a normal drive. Honestly for gaming performance, raid0 vs a good drive, is a waste.

IF i were smidsy i'd stick with the Raptor 150GB. :rolleyes:

My way works out cheaper, faster and more redundancy... (as it includes a RAID1). 96MB/s average read, 400MB/s burst, 12.8ms access time. Not bad... + I'll save about £20.
 
£20 cheaper plus redundancy i get, but are 2x Hitachi 80GB drives on RAID0 with the small bump due to RAID1 really faster than a Raptor 150GB, at least in access times?
 
Woah! I didn't know I would stir up this much of a debate.

I went RAID 'cos I got bored of my setup and wanted another toy to play with. So i've got it.

Just need to check. How do I find out that I am really, really running RAID0?

I've got botrh my 74Gb raptors in here now but my C drive is reading 125Gb. Should this be correct for RAID0? Any one?

Thanks again guys.

Agent :cool:
 
damn it!

I knew that it wouldn't work first time round.

Oh well. Just got to figure out why its not working.

Also its picking up my C drive to be 138MBs, I dont think this is correct...

I'm sure someone on here has suggestions as to what you are doing wrong. Don't fret man, help will be available. :)
 
Cool, cheers bud.

Its proving to be more difficult than I though. The mobo manual is nothing like what its actually doing when setting up RAID.

Does anyone have an A8N-SLi Premium with BIOS version 1.08 with HDDs in raid? If so, a little help please... :(

From the picture you posted, it looks like your drives are running in RAID0, especially considering

1. The results from the Average Read in MB/s
2. The size of the harddrive.

However the reason yours is probably not matching the other posts is due to the controller being used, or something else with your setup. It really looks like the SILIMAGE controller is running across the PCI bus, and being limited compared to the NFORCE which has direct access without PCI bus.

Again looking at the picture you posted and going of the size of your harddrive, your drives are definetely running in RAID0 at the moment. The reason there only showing as 138MB instead of 148(74x2), is due to the amount you lose due to conversion from 1000bytes/1024 bytes........or whatever.

Edit - in fact if you scroll down in the thread mentioned above, to the very last image, you will also see somebody elses setup where the controller is maxing the BUS, giving exactly the same results as your seeing.

Ok, thanks for that bud!

I've been trawling the Asus forums and have found the solution!

I was using the RED connectors when it should have been BLACK. Aparently the black ones use the PCI-E lanes and the red ones use the PCI lanes. So i'm in the black ones and have the HDDs working now - Just in the middle of installed Windows as we speak...

Ah, all in and working!

As you can see below I am getting far better results this way!

Agent out!

Hmm, the burst speed is better, but Random access is exactly the same and average read speed actually went down a fraction. Good job we enjoy loading windows!

I ran a pair of WD Diamond Max 9 120's in Raid 0 , as a boot disc plus data partition, and lost one of the drives after about 3 months. The drive was replaced FOC but it was a bit of a pain. Windows response was great, but I replaced the Raid with a 36GByte Raptor and actually feel the Raptor is quicker, though benchmarks show the Raid to be potentially faster.
