Seagate Pro Internal HDD Reviews
As advertised in non-retail box
By Tom
Rated 5 out of 5
Date: 2026-05-07
The hard drive disc came in non-retail box. Also, the actual HDD is also non-retail version that doesn't look like the photo. But it has correct model number on label. I used hard drive utility and verified 7200rpm. I also used HDD utility to write and verify every sector without any error.
Huge! Designed for a NAS

I am running two of these as part of the array in my Terra-Master T4-423. They replace 2-14TB drives. They slotted in and synchronized without a hitch.
