The specs between the WD Se and WD Red Pro will be pretty similar. The Load/Unload is higher on WD Red Pro because of lot of consumer based NAS units have a sleep mode, so the drive will reach a load/unload count quicker than a higher end NAS. Also, this is just a counter and doesn’t mean that a drive will fail when it reaches this threshold.
The Non-recoverable errors should be the same for both drives. I believe that there was an error in the documentation that they are correcting.
