Storage system bottleneck after sitting idle
Announcing the arrival of Valued Associate #679: Cesar Manara
Planned maintenance scheduled April 17/18, 2019 at 00:00UTC (8:00pm US/Eastern)Do SSDs really have a much shorter life than HDDs?Intel SRT / RST gives “no boot device” error after two rebootsHow can I create a single RAID volume with a single HDD?Two SATA 2TB drives in RAID-1 configuration; only one 6.0gb/s port openit possible to disable HDD after 20 min idle but not SSD (Windows 7)How to create a Mirrored Volume in Windows 8.1 - mirror option missingProblems creating a bootable RAID volume when imaging from HDD to SSDMy SSD drives have a very slow write speed (800MB read / 5MB write!)Healthy unknown partition created in WS2012 R2 storage pools - How to recover?Change SATA mode to AHCI before reinstalling Windows on new drive - possible lose of data on non raid drive?

I am working with a computer system that acquires data from a digitizer card. When the computer sits idle for 1 hour or more, and I begin data acquisition, I receive an error relating to not acquiring the data quick enough. I simultaneously hear the hard drives begin chattering. I know from past investigations, that the software that controls data acquisition is sensitive to high (long) write latency. After receiving the error, I try acquiring again and there is no issue.
I suspect that the storage system is being put into a low power state or idle state. Perhaps the heads are being parked. I have tried the following:
- I have set the hard drives to never spin down through the Windows 7, Control Panel, Power Options menu.
- I have set AHCI Link Power Management (LPM) to "Active" which to my understanding means neither host initiated or device initiated power management is allowed.
Neither of these have improved the situation. How can I confirm that the issue lies in the storage system?
The system has the following specs:
Core i7 7800X
64GB RAM
2x 240GB SSD Corsair Neutron XTI SSD (RAID 1)
4x 4TB Western Digital WD4002FYYZ (RAID 10)
