Changing the stripe size on a newly created RAID 0 set. Possible?

[Panagiotis_Mela]

Good day to all,

This is my first posting in the ROG Asus forum, hoping that I will remain an active member in it for a long time.

Yesterday, I managed to set up a new PC, based on the following (basic) configuration:

• Motherboard: Asus Z170 Pro
  
• CPU: Intel i7-6700k
  
• RAM: G.Skill TridentZ 32GB, 3200 MHz
  
• PSU: Corsair HX1050 80 Plus Gold, 1050W
  
• System Discs: 2 x Samsung 850 Evo, 120 GB in RAID 0 set, connected on the two SATA Express ports of the motherboard
  
• GPU: XFX Radeon R9-380P-4DF5, Double Dissipation 4GB GDDR5
  
• CPU Cooling: Corsair Hydro H80 CPU cooler
  
• Optical Drive: Pioneer BDR-209EBK BD-R Drive
  

The hardware has initially been mounted on a CoolerMaster Test Bench V1.0 CL-001-KKN1-GP, specially modified to accept heavy components (like for example a big GPU and the Corsair CPU water cooling).

I intend to put everything in Lian Li PC-A10A computer case, equipped with some more additional hardware, like storage HDDs, etc., but for the time being, I need to keep it on the Test Bench, to finish and complete the installation of the OS and the basic required software.

When I started configuring the basic characterisitics of the system through the motherboard BIOS, I had first of all to upgrade the BIOS to the newer version 1702 (mine was the older 1302 version), succesfully done through the Asus EZ Flash uitility and a USB stick.
Then, I went in the Advanced Mode -> Advanced Menu -> SATA Configuration -> RAID Mode to create a RAID 0 set with the two Samsung SSDs. At that stage, I specified a stripe size of 64 kb on the set to be created. I saved the changes and I restarted the computer.

After that, I inserted the Windows 10 Pro DVD in the optical drive and I loaded the OS on the set. When everything was succesfully finished and the first updates were downloaded, I checked once more the BIOS and I discovered that the RAID set stripe size was set at 16 kb. For some reason, perhaps by my mistake, the "64 kb" set was not kept.

I tried to see if I can alter it in BIOS, but I could not find such access at first glance. Therefore my question is:

Can this be altered, by keeping the OS or should I have to delete the set and reload the OS again?

Thanks in advance.

I was finally forced to delete the RAID set and rebuild it again, this time ensuring that the specified 64 kb stripe size remains there. I had, of course, to reload the Windows from the beginning and the drivers from the motherboard CD. I will return with further results from the new PC.
