Need help building a new Raid on ASUS P6T6 WS

post #1 of 3
Thread Starter 
My computer is currently just on a single WD 640 Caviar Black drive connected to my ASUS P6T6 WS. I recently purchased 3 new 500gb WD Caviar Blue hard drives and a new Crucial C300 64gb for a good price and I and looking to rebuild my system's storage.

What I am trying to accomplish is to have the SSD as the boot drive and then the rest of my hard disk drives in a RAID of some sort as a secondary partition.

I plan on following this tutorial after properly configuring the raid:

I'm trying to figure out a couple of things before I jump in and tear everything apart. Here are a number of issues that I am inquiring about:

I'm really not interested in purchasing a separate RAID card but I want to know what kind of performance hit I will incur using the ICH10R's RAID solution. (Intel Matrix Storage Manager)

There has been a couple of mentions of TLER in a couple of threads that I have read. What kind of issues I would run into regarding TLER? Is it necessary to enable TLER for my drives to run in a RAID?

I also want to know if its possible to build the RAID with 2 or 3 of the new hard drives at first, so that I can migrate any data over to the new array from my old 640gb drive before I add the remaining drives to the array. I know using external storage of some sort is possible and easy but I don't have any on hand and although I am looking to purchase some sort of back up storage in the near future, I don't want to wait for that before I rebuild.

I have also been looking for some up to date benchmarks regarding a RAID 5 vs RAID 1+0. I'm currently leaning towards RAID 1+0 for its ease of setup and its increased reliability but if the real world performance hit is negligible I would prefer RAID 5. The array is not going to be very write intensive. It is mostly going to be used as a place to install programs I can't or don't want to fit on the SSD.

Any tips or ideas would be greatly appreciated. I also understand that spending some money would alleviate some of the many issues I have but to be honest I don't really want to go in that direction. I would still love to hear your advice though and if the monetary cost is not unreasonable I may consider it.

Thanks for taking your time to read my first post here on OCN. I've been a member since 2009 but have always found the answers to my problems by myself. Setting up a RAID is new to me and I'm unfortunately finding it a challenge. Thanks again.

First and foremost, be aware that RAID 1+0 requires four drives, where as RAID 5 requires three.

Additionally, while the ICH10R is actually a pretty good controller, apparently the RAID 5 implementation sucks. Also, from what I have read here and elsewhere, the ICH10R requires TLER to be enabled on drives which are members of an array, and the Caviar Blues do not support TLER.

Of course this won't matter if you don't get any bad sectors...

How likely/often am I going to get a bad sector?
