Our custom power testing samples each drive for a period of three minutes, across each workload. In order to offer more granularity, we sample the power in one-second intervals.
Analyzing our workload power consumption, we found the Seagate Archive HDD to start out just above 6 watts during both random read and write. Moving into sequential workloads, power rose slightly up through 7.2 Watts then took a slight dive back to 6 Watts as the cache worked the beginnings of our sequential write workload. As the cache emptied, the drive's power ramped back up to a peak of 7.8 Watts to finish off our testing.
Throughout testing, there were several times where I had to hold myself back. It wasn't that the drive was not living up to expectation as it was surpassing mine by miles, but there were many times where I just wanted to take a few of these drives and throw them into a NAS and build an array for the pure amount of storage capacity they can produce. As I began to browse through forums, it appeared that I certainly wasn't the only one that had the itch as many users were asking if the Archive HDD is up to the task.
The unofficial declaration for the Archive HDD is that it's designed for high density cold data applications; or the retention of inactive data that is rarely accessed. That last sentence surely rules out RAID use, but not necessarily NAS use. With modern NAS systems, storage pooling has become the go to way of organizing data, so if one were to create a single drive pool for pure backup and not constant media access then it is possible the Archive HDD would be a feasible solution. With that said, for consumers that have many terabytes of data they are now backing up on many disks, the Archive HDD is a solution that can be powered up, copied to, and then shut down.
Throughout testing the Archive HDD, we found many situations where the drive was able to surpass performance from both the 4TB and 5TB Desktop HDDs with sequential read and random write being maybe the only problem areas for the drive. Sequential read numbers hovered around 110 MB/s, while writes picked up to 200 MB/s, and when moving to random performance, we found the Archive HDD touching 450 IOPS in random read. In workload testing by far the biggest surprise was how well the Archive HDD handled the mixed data sets, with Database topping 534 IOPS followed by 430 IOPS in File Server. Web Server and Workstation also proved good numbers at 305 and 229 IOPS, respectively.
Last, we ran the Archive HDD through power testing to see how close our numbers would shake out when compared to marketing, quite surprisingly they were almost a dead match as Seagate makes note of a 7.5 watts average we were right there with them through sequential read and write, while random read and write proved lower power consumption near 6 watts.

The Bottom Line: Seagate's Archive HDD is a solid, reliable solution for those that want the means of backing up years worth of data into a single drive. In addition, the power management and low initial cost coupled with the performance of the drive make it one of the best all-around drives on the market.
