Slower Parity Sync After Adding 3 Drives

[dlewis23]

I got my build fully built and running this morning but I'm not sure if this is a problem. For some reason after I added 3 more drives to my setup this morning, the Parity Sync slowed speed slowed down by about 1/2 the speed it was going at originally.

 

It was going at about 50 - 60 MB/s then after adding the other dives its only going at about 25 MB/s.

 

Right now I'm running 9 drives, and the only thing that looks a little odd to me is it says that 2 of the 3 drives I added are IDE but they are not. Every drive is SATA. Not sure If I should be really concerned about that.

 

I attached a system log. Disk 3, 4, and 5 are the ones I added when I noticed the problem start.

Is this your current setup?

Likely a bios setting that needs to change from IDE to AHCI. Some MBs have default settings for ports 1-4, and ports 5-6. I believe my Asus AMD board does as well.

Well chaining that in the bios fixed that problem. Now I'm syncing again at 50 MB/s.

 

Thanks
