Getting Impossibly Slow transfer rates on raid array. Hard drive likely going bad, but everything is saying it's okay... and it's wrong

Slow transfer rates on a MediaSonic RAID array could be caused by several factors, even if the hard drive itself shows no issues:
1. Interface Limitations: Although USB 3.0 and eSATA support high theoretical speeds (up to 5Gbps and 3Gbps respectively), actual throughput is lower due to delays from media arbitration, OS processes, and other system overhead.
2. Controller Impact: The performance may be affected by the specific host controllers used. For example, USB 3.0 through a Renesas PCI-e controller and eSATA through an IOCREST SiI3124 controller could influence actual data transfer rates.
3. High CPU Usage: If the system is running background processes like video playback or scans (e.g., thumbnail or DLNA scans), it can consume CPU resources and reduce transfer performance.
4. Noise and Pixelation: Noisy operation and video pixelation suggest the device may struggle under load, possibly due to internal data handling or hardware limitations.
These factors combined can result in slow transfer rates despite no apparent hard drive failure.
