I am considering buying a DZ68BC motherboard for a new computer using an i5-2500K CPU.
The computer will have 2 SATA drives in a RAID 1 configuration using the Intel SATA ports and Z68 chipset.
Does anyone know if the Intel Smart Response Technology using a 20 GB SSD will cache the Raid Array?
Thanks, spearson, for your prompt reply to my post.
Your answer triggers some follow on questions/consideration:
The motherbpoard has four (4) 6 Gb/s SATA ports (2 Z68 and 2 Marvel) and four (4) 3 Gb/s Z68 SATA ports.
Will two (2) 6 Gb/s drives for the RAID 1 array on the Z68 controller and a SATA III SSD (6 Gb/s) on the Marvel controller work for iSRT?
Or would it be more reliable and stable to use two RAIDed 3 Gb/s SATA drives on the Z68 controller and place the SATA III SSD also on the Z68 controller's 6 Gb/s port?
If both will work, Is there a performance difference? What is the best way for me to make RAID1 with iSRT?
Thanks for your help with my question.
You can read section 1.6.2 of the board's Technical Product Specification (TPS) for more information regarding its SATA/RAID architecture. Here's the pertinent information:
Thanks again, you were very helpful. I just ordered the DZ68BC motherboard, an Intel 320 series (40 GB) SATA II SSD, and two Seagate 6 Gb/s SATA drives.
I will use them per the third bullet in your reply to my question.
Hopefully the speed of the Seagate SATA drives will work on behalf of non-cached random file access (such as database) while the SSD caching provides the speed boost for frequently used programs etc.
You might be interested in an issue I've run into between my DZ68BC motherboard and a new Seagate Barracuda ST3000DM001 3TB hard drive. This drive is supposed to be SATA 3 (6 Gb/s), but only shows in the bios as a 3 Gb/s drive, even when connected to one of the Z68's SATA 3 ports. More details can be found in my post at the Seagate support forum:
While I'd love to know if this "handshake" problem is on the motherboard side or hard drive side, it probably doesn't make too much practical difference: even running at 3 Gb/s, this drive benchmarks at over 200 MB/s read/write speed, which is about as good as it gets for a single mechanical hard drive.
Good luck with your build,
A couple of further comments:
Good luck with your build...
I hope you have your colors backwards; the TPS indicates light blue is Marvell and (dark) blue is Intel (PCH). As for RAID support, while the TPS indicates that RAID functionality is only supported on the Intel headers (see section 18.104.22.168), one of the BIOS engineers verified that RAID is indeed a choice in BIOS Setup..
