More on CPU specs of the ReadyNAS Pro

Backups are to two USB drives. Each drive backs up different shares. One is connected to the ReadyNAS and backs up via FrontView. The other attaches to my desktop and backs up via Carbon Copy Cloner.

Here's the SMART data for the raid set. Some of the disks have Raw Read Errors but they check out as OK with SMART

The problem last time was with the USB drive connected to the ReadyNAS.

I'm having trouble with this drive again so maybe it's really starting to go? I can try running fsck on it again and see what it says.

I'm still concerned about the RAM and will send it back if it's bad. I downloaded the logs and it checks out:

* Jumbo frames are disabled on interface 1.  If both your switch and clients support jumbo frames, you can enhance your write performance by enabling jumbo frames on this interface.
* Jumbo frames are disabled on interface 2.  If both your switch and clients support jumbo frames, you can enhance your write performance by enabling jumbo frames on this interface.
