Just bear in mind that two OCZ v2 Core 30GB SSD on a decent 3rd party RAID card is cheaper AND faster than one Intel drive!

Then please someone tell me WHAT relatively cheap raid-controller I have to
use to make these baby´s work well ,.. since the offer ends tomorrow :D
 
Highpoint RocketRaid 3120 if you're on a budget, although PCI-E 1x will limit your transfer rates.

Just get something with at least PCI-E 2x and 128MB or more onboard memory - one of the better rocketraid models - about £170+ I think.
 
The Adaptec 2405 is a screamer and works great with the OCZ Core V2.
They are PCIE x8 though, so that really needs a x38 or x48 chipset motherboard, unless you don't mind losing x16 on your graphics card.

The Rocket RAID 3120 card is PCIE x1, but as found, they are not fast enough to handle the throughput from 2x Core V2 in RAID 0.

With a good hardware RAID you can expect 280MB/s reading speed and 200MB/s writing speed. on the Core V2.

Where is the source for the two OCZ drives being faster?

We have found nothing of the sort in our real world benchmarks to suggest this.

What do you want to see?

I have a few RAID cards here I have been testing for work with OCZ v2 drives.

The Areca 1220/1231 produced the best results so far, but dont scale into multiple drives very well very well because of processor limitations on the RAID card.

The 1220 managed an Average of 320 MB/sec in HD Tune, but its a more pricey RAID card than most.

Let me know what you want to see and I just need to swap cards and I can do it for you.

Also, ATTO is the reccomended benchmark for SSD, would love to see the Intel drives in that.
 
Can run ATTO in the morning. :)

Think I have misread the OP with the two drives beating TWO Intel drives.

The OCZ drives are much better value for money at the moment but on onboard hardware I must say the Intel drives seem to be scaling better.

Don't have a dedicated controller card for benching use so its a little hard for me to get some Intel SSDs v OCZ round up on them but I may be able to do a mini round-up in a Rampage II Extreme.

£ per mb of transfer should give a good value indication I think.

Thanks Dee, interesting reading, and good info,.

I have right now a P5Q (P45) ,.. but due to div asus-troubles I would swift
it to some Gigabyte, the intention was a P45 again,- Graphic-card is based
on HD2600XT, is sold as "PCIEx16", but I dont know if being narrowed down
to "something" less matters ? and will harm anything in my case ?

Will be NO gaming, audio and video production only, (Cubase/Vegas etc),..

Guess the 2405 is what to go for in case,.. with a little luck 100£ on ebay,
maybe, but if giving the full street-price where I live the I guess the price
for the hole setup is getting a little to high ,.. unless the 2405 is usefull in
other ways also ,..... hmmm

The 2 x OCZ Core V2 for OS obviously , so 2 slots left on 2405, but for the
mass of mega HD-video-files, storage, and rendering,. I guess the onboard
matrix-raid is just as good, but one could offcourse say that I have the
full amount of sata-connections still free on the ICHR10R due to the 2405
and this might come in handy when building up the other arrays

Wait, I thought the OCZ drives had the stuttering and locking up problem which is internal to the drive. No RAID card is going to fix that problem.

I guess Dee already explained this real good here :D

I just need to be sure about my related motherboard-issue, I whant to stay at P45, due to high FSB,
and also to be prepared for 16 GB ram, hopefully this x16/x8 thing is not any problem with HD2600XT,
I see now that the PCI-E configuration seems very diffrent from one P45 board to another P45 board,
I go for Gigabyte, maybe DQ6, Gigabyte should also have less problem with 4x4 16GB ram than ASUS

Well guess its to late now, the offer is about to end, but to me it seems
like f.eks. this P45 board has 2 x16 slots one running x16 the other x8 ?

LINK TO DS3R

1. 1 x PCI Express x16 slot, running at x16
2. 1 x PCI Express x16 slot, running at x8
(The PCIEx16 and PCIEx8 slots support ATI CrossFireX
technology and conform to PCI Express 2.0 standard.)
3. 3 x PCI Express x1 slot
4. 2 x PCI slots

I think as soon as you plug (any) PCIE card into the second PCIE socket, socket one (x16) will drop to x8. I believe that only the X48 chipset and possibly the X38 can support true TWIN x16 PCIE.
 
OK ,.. decided to let it go ,.. but thanks for all the help, Likely 2600XT/256 performs very
well x8, 2600xt model was sold an-mass in 512 version AGP x8 (speed close to x8 PCI-E)

But 2 hours google would not confirm this, no gaming, but I need dual-head 1920 x 1200
in 32 bit color-deept, I decided to not take the risc,. will bye yet a WD640BLACK instead
 
Just saw another thread suggestion that even on P35 there should
not be the above montioned PCI-E problem LOOK HERE

I would realy be happy in that case, and go even for the 60 GB V2
models since these can be had for ok prices in germany right not

It's a complete lottery. It depends if the motherboard has 16 or 22 PCIE lanes. In any case, the 2405 is a PCIE x8 card, not a PCIE x4 card. One person that i know of on OCZ's forum tried it with a P35 and can't get it working properly. http://www.ocztechnologyforum.com/forum/showthread.php?t=46728

P45 is even more unclear as the specs clearly state. 1 X16 or 2 x8.

The only sure way of getting the 2405 working correctly (without dragging down the PCIE graphics) is X38 or X48. A better solution for the P35/P45 would be a x4 RAID card like the Adaptec 3504.
