Opinions on correcting disk contention issues during Acronis TI backup
Hello All,
I am completing a change over from a 7 year old eSATA external 12 TB (RAID 5) enclosure to a new USB 3.0 external QNAP TR-004 40TB (RAID 5) DAS enclosure.
My backup destination device has been and will continue to be a USB 3.0 Western Digital MyBook 12TB external storage Unit in RAID 0.
When I was backing up the eSATA 12TB storage to the USB 3.0 WD MyBook drive using Acronis TI 2019, I never had any performance/contention disk issues accessing server disk data on the eSATA during the backup.
But now, possibly a normal expectation, backing up the new USB 3.0 QNAP DAS to the USB 3.0 WD MyBook has major disk access performance/contention to the QNAP Server data drive. This impacts other home server disk access uses during a 12 to 24 hour large backup. I am attaching both USB 3.0 devices directly to the motherboard back ports that are: 1 - directly attached (motherboard) Intel X99 USB 3.0 port, and 2 - the other device being attached to USB 3.0 port on the on-board (motherboard) ASMedia hub controller chip, which ultimately also connects back to the same X99 chipset.
When looking in Device Manager (Connection View), both external disk storage devices are connected to different USB 3.0 hubs, but combined into the same USB 3.0 “Root” Hub. There are no other real choices of using other USB 3.0 ports on the motherboard.
So my thoughts are this: Would installing a PCI-e USB 3.0 card into a PCI slot to attach one of the two USB 3.0 external drives allow a different data transfer path in and out of the X99 chipset, like between the eSATA to USB 3.0 path that worked before that didn’t cause the server disk data disk contention during backups?
Thanks in advance.
Scott
