Default RAID 0 + Muiltiple Drives

I read over at another forum that there was a rumour going around that if you install 4 Hard drives in a Raid 0 array that your speeds SHOULD be at around 400MB/s. He did not mention if it was using a onboard controller or a RAID card but would there be any truth to this? I have always boycotted RAID as I do not believe that they do anything but use more power and waste space for minimal performance gains.

If this is true then I MIGHT go with 4 x 640GB WD Blacks for my new I7 build....but I will not shell out for a raid card....onboard raid controller on a EVGA X58 only.

Can anyone shed some light on this please?

Thank You for your time.

Depends on alot of factors.


Here's a demo towards the ridiculous end of the scale:
Next Level Hardware.com: Battleship Mtron

They RAID0ed a bunch of MTron SSDs. Let's just say they copied a 1GB file in 4 seconds.


If you use the proper hardware (meaning no crappy*onboard RAID) and fast drives, it should scale pretty well.

*Intel Onboard isn't bad, but I'd still go with a RAID card.

SSD RAID0 comparison (ARC-1220, Perc5/i, ICH10R)

there's a good comparison between onboard and not, even though you're not interested, its a good read.
I'd recomend SSD's over 4 HDD's. THeir acess time is awsome, and their speeds are good.

This is what a dream for me would be. I'd love to have this in my system since I do a lot of copying and conversion...but yes SSDs are the way to go now for RAID. There's really no other option now that you can find some fairly reasonably priced SSds on the market now.

Newegg.ca - G.SKILL FM-25S2S-64GB 2.5" 64GB SATA II Internal Solid state disk (SSD) - Solid State Disks

i got 2 of those.. i love them. I used ATTO to test out different stripe sizes to compare to lowfat. I'll have to post them. Im in the middle of taking windows 7 off, and putting windows xp back on them.. so, i'll do that after

But what about the life of the SSDs? That is the only thing holding me back from getting a couple.

they claim over 1 million hours.. however, i do not believe they have been around enough for this to be proven.. i may be wrong though..

Wait....I thought that it was based on number or writes....not hours....

How can they make that claim?

One big benefit to SSD's as far as I concerned is not having to waste time running defrag, they actually recommend against it...
