Any help would be appreciated!

 

Bought the X10SL7-F + E3-1231V3 like so many other people have. Problem now is that my transfer speeds both within the array and from the cache drive to the array are INSANELY slow and by insanely slow I mean the best I've seen is 2MB/sec. My previous HW was an old Intel motherboard with an E8400 Dual Core Duo and would do the same data transfers at 100MB/sec plus.

 

I saw no change after flashing the internal controller firmware to the recommend IT version. Look for any assistance the community can give/offer.

 

Unraid version: 5 Pro

 

Need to know the rest of the parts, drives, where connected, controllers, etc.

No other controllers just the onboard SATA ports, all WD drives (except the cache) as shown below. Using the same drives and cables I had before the MOBO, CPU and Memory swap:

Im now having the same problem, out of the blue. 30mb/s is the top speed i get during parity check and server struggles to do anything else during that...

Barring a defective board/CPU (seems unlikely), this is likely either cables or power.

 

Is this an issue with both reads and writes?  ... or just writes?

 

What power supply do you have?

 

Without the diagnostics, we can only speculate.  Tools -> Diagnostics

It's odd. Admittedly i have one drive with failing SMART, which i need to replace... but these Seagate Desktop drives were a bust. Warranty is too short...

 

I also have a dubious PSU... I need to give my server an update.

 

Attached are some things, but still not sure if they will help.
