Sure glad I followed your advice on getting the DS920+ a year ago. Along with that I purchased two WD Red's 8TB and two N300's 8TB.

Wondering if you have any information / knowledge of the Toshiba SMART info ID 220 - Disk_Shift attribute? Mine are reading over 150m counts for Raw Data. Probably a hex format but nonetheless, the definition states this is a measure of the a distance the disk has shifted relative to the spindle.

Even Toshiba's tech support can't tell me if having those "counts" constitute the drive is faulty. I have read some comments that others have RMA'd their drives only to get replacments that have large Disc Shift counts.

I have run both short and extended SMART tests and all pass with no errors.

Do you have any info on this at all?

The Disk_Shift attribute in the SMART data of a hard drive refers to the distance that the disk has shifted relative to the spindle. It is usually measured in micrometers or millimeters.

A high count for the Disk_Shift attribute could indicate that the drive has experienced mechanical stress or vibration, which could lead to premature failure. However, it's important to note that some drives may have high Disk_Shift counts even when they are functioning normally.

In general, if the drive is still under warranty and you have concerns about the Disk_Shift attribute, it may be worth contacting the manufacturer's technical support for further assistance. They may be able to provide more specific guidance based on your drive model and usage. Additionally, if the drive is still functioning normally and passes SMART tests, it may not be necessary to replace it at this time.
