Fastest onboard raid controller?

cavemanoc · 16 Apr 2008 at 19:23

I'll be building my new rig over the next couple of months and have decided to move away from a Pci-e add-in raid card (scsi I'll miss you -sniff-)

Will be looking to raid probably 4x320Gb F1s and was wondering what the fastest onboard solution is at the moment - will I get away with something like the new p35 DFI or is there better stuff available?

Intel ICH10R controller will be out with the release of the P45 boards soon....

Is the ICH9R considerably faster than the offerings from nvidia/Ati?

Mmm..I'd wait until somebody in the hard drive know can tell you - but with 4 of those drives running (in RAID 0 is it?), an onboard controller will be a bottle neck..

A couple of examples of what the ICH9R cont can produce (using RAID0), Here and Here

The ICHxR is half decent for using RAID0/1 setups, but not great in RAID5 where the "write" value suffers.

The ICH10R can only be better I reckon....

Are you wanting RAID5 or just RAID0/1? If it's RAID5 forget it and get a proper card, otherwise the mobo RAID is fine.

P45!? What on earth is this bringing to the party and what is the point of releasing a new chipset now when Nehalem is not much more than half a year away?

Sorry - should have said - I'm only interested in Raid 0, and purely from a speed point of view. I run raid 5 on my scsi's atm (perc 4e/dc) but as you said, without a dedicated card it is pointless.

You'll be fine with onboard then, not much thinking required for RAID0 so it's okay onboard.

Ugh lol fair play - that is pretty astounding!

highly doubt ICH10 will perform Raid 5 any better than it currently does.

same old same old...if you want performance for parity calculations get a hardware solution.

onboard for raid0/1 is fine for most purposes.

As 2 completely separate statements, "The ICH10R can only be better I reckon" was not written with the thought in mind that the ICH10R cont would somehow implement RAID5 any better than ICH9R, because as you correctly say, "if you want performance for parity calculations get a hardware solution."

I wrote "The ICH10R can only be better I reckon" with the thought in mind that each new generation of the ICHx(R) is usually better than the preceding one.
