Two RAID 0 arrays on the same Z87 controller?

Dear All,

Am currently running a couple of Intel 520 SSDs in RAID 0 on an ASUS P8P67 motherboard. It runs beautiful with no problems. In addition, I have a couple of old Intel 510 SSDs that I tried to set up in RAID 0 as well. Unfortunately the combination of two RAID 0 arrays is not stable (the system hangs randomly) on the ASUS P8P67 motherboard, see:

https://communities.intel.com/thread/11273

Now, I am wondering whether anyone in this forum has tried to run two arrays of RAID 0 on a Z87 chipset?

Thanks for sharing your experiences.

Best,
Philip
 
Can't say for certain on the Z87, but I've got two RAID0 arrays running on my Z77 chipset in my workstation (specs in sig). No stability issues to date (1.5 years later).
 
Thanks Zxian - sounds good!

And you ran both of the arrays on the Intel controller (and not one of them on a third party controller)? I try to avoid that - although I am not sure that is wise.

The nice thing about the Z87 is that it would provide six SATA 6 ports so all four SSDs could run on SATA 6.

Cheers!
 
Both of the arrays are running on the ICH10R controller (the Marvell controller is disabled in BIOS).

There isn't any real downside to running multiple arrays on the same controller unless you expect to be running into bandwidth issues between the controller and the rest of the system.
 
You will probably run out of bandwidth with two arrays. I know that I can only get about 1.5GB/sec max serial read out of my array. Still not bad, but a real RAID controller is necessary to get the most out of SSD RAID.

does not compute...

u guys should have a net bandwith of 6GB/S open over the PCH on a Haswell processor...
it would take roughly 12 SSD's in R0 to cap the bandwith on haswell.... assuming each ssd had the potential to do 500MB/s

The OP would be safe from oversaturating his bandwith as long as he keeps to the 12 disk minimum limit... even then the SATA ports on board he is limited to.
So technically the OP wouldnt have any issues adding all 6 drives in R0, let alone 2 x R0 2-disk arrays, as they eat up less bandwith then having 4 drives in R0.
