Slow Write Speeds - After Hard Drives Turn On - Power Management

Hi,

I am running firmware 1.05, RAID 1, 2 x 1 TB Western Digital WD10EACS drives

My write speeds are ok without Jumbo turned on (I get worse performance when I set Jumbo 9000 and 4000 MTU on both DNS and laptop NIC). I get around 13 MB / sec.

However, when my hard drives turn off after 5 mins due to Power Management and then turn back on again due to activity, I get really poor performance in the order of 10 or more times worse.

I need to restart the DNS before obtaining good transfer speeds again.

Is this normal?

Cheers.
