Doesn’t matter which drive (enterprise or other) they will all show up as normal 14TB that work on SATA.

It is a common practice for drive manufacturers to put “seconds” into USB enclosures. Can’t say for sure in your case. You might be able to tell by opening the case and looking at the disk label.

It’s fairly likely that the Exos drive you received failed to pass some Seagate test to qualify it as an Exos.

Couldn’t find a list of the “recovered” Dr. Who episodes anywhere. Anyone have the titles?

Curious if I have them in my archives.

The benefit to using your own router is increased flexibility in configuration.

If you are happy with the XB8 as a router, then there isn’t much benefit to using your own router.

Your Netgear AX5400 is a router, not a modem. Unless you’ve configured your XB8 in bridging mode, it is also acting as a router. That gives you double NAT which is going to slow you down some.

Your choices are to bridge the XB8 or eliminate the Netgear.
