2 Striped RAID-0 Arrays on Single MOBO

[Collider]

I have an Asus P6T Deluxe v2 and wondering if it's possible to setup more then one raid array using the on-board controller.

I don't know if the on board controllers are limited to only one raid array, never tried setting up more then one at a time.

Does anyone know if this is possible or would I have to get a separate raid card ?

Why do you want 2 separate RAID0 arrays anyway? You may want to just switch to an SSD or get a cheap one as a cache.

Well I currently have 2 x 640GB WD Blacks in RAID-0 that I want to keep, and it is 2 SSDs that I am trying to stripe for my OS drive (currently have 80GB SSD).

Also with 24GB RAM is there any benefit to considering a Cache drive?

Most MB's I've had with SATA Raid Option you enter Bios and Enable the OnBoard SATA Raid, Reboot and enter the Raid Utility while the MB is Posting to configure the Raid Array. If you have 4 SATA controllers you should be able to assign which SATA Drives you want to run as SATA Only and which ones you want to run as SATA RAID. If you choose to run all 4 as SATA Raid you have another option to Group them in Pairs as 2 separate Arrays and further have the option of choosing Raid 0,1 ...etc for each Array.

I have an Asus P6T SE (shitty edition of your mobo) and yes its possible.

why? more like why not if you have enough drives to do it...

off the top of my head, here are just a couple reasons I do it:

1. I have several SSDs and HDDs, and I certainly don't want to mix the SSDs and HDDs, and certainly try to avoid mixing drives if they have different performances or capacities (ie I wouldn't want to mix my 256GB Samsung 830s with my 128GB Crucial M4s, and I wouldn't want to mix my 1.5TB 7200RPM drives with my 2TB 5400RPM drives)

2. its cheaper and easier to invest in and upgrade a system with 2 drives at a time rather than planning out a larger single array of 3+ drives

3. while a larger single array can have its benefits (greater capacity and sequential speeds), having separate drives/arrays can actually be better for work flow

Great, thanks - going to give it a shot this afternoon.

Does anyone know if having 2 SSDs in RAID-0 without TRIM support would be a viable option? Meaning if performance degradation will be noticeable.

as long as each array have its own controller. you can run as many array as you want.

connect the drive to the proper port, log into the array utility, and setup. ez as that.

as for trim support on raid. think only intel chipset offer trim support for raid.
