Having carried out many data transfer tests on my new system I thought it was time for some baseline measurement tests.
I ran Smartcl and everything, apart from the following two items, were as you would expect. These two items were both way out of parameters on all 4 drives. I ran Scrub with no change.
The drives are 4 new WD Red 2TB in a 2x2 mirror. The disk controller is an H200 patched to 20.00.07.00. Freenas is 11.0.U4.
The 305 watt power supply is driving the 4 drives, an E3-2270 CPU and the hard disk controller.
These are the problems reported.
Spool up time on all drives is around 4500.
udma_crc_error_counts are all around the 800 mark.
I replaced the disk controller cable with a second (also used) part but the crc counts did not change. Since all 4 drives are showing the same indications and I tried a replacement controller connection I am thinking that the H200 is bad or perhaps the power supply is failing. Reflashing and replacing both of these parts is going to be time consuming since I do not have spares on hand.
Before I start the replacement route what do the experts think?
Thanks, Brian
