  • Seagate Archive 8TB ST8000AS002 HDD Review

    Conclusion  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.

    Plus

    • Increase capacity at the same density and much lower cost
    • Strong read performance
    • Excellent burst write speeds

    Minus

    • Lower performance in sustained write tests (as expected)

    Conclusion Utilizing SMR technology, Seagate Archive HDD drives can pack up to 8TB capacity into a single 3.5” form factor drive. As the name implies, the new drives are intended for use in large-scale datacenters as opposed to being used for more general RAID purposes. The SMR technology being used is more beneficial for read, or data retrieval, purposes like active archive. The drives are also more efficient to run, and have a lower cost than traditional enterprise-class 6TB drives. Seagate Archive HDDs are drive managed SMR meaning they can be used with any OS.  As far as its performance goes, the Seagate Archive HDD threw a bit of a challenge our way. At the moment, we don’t have a benchmark in place to measure hyper-scale environments with massive object-store filesystems that can distribute parity data without the use of RAID. Instead we built out a Veeam backup test to create a similar data model. In our test we saw, as expected, the SMR drives took much longer for a traditional full backup, averaging 30MB/s. However we saw sustained read speeds during a 400GB VM recovery in excess of 180MB/s, which is really the core metric. Given the low cost/TB, the drives do very well here if the backup admin can get a little creative. Design your backup window to work with the lower sustained write performance (or design it to fit inside the burst write window completely) but still have your data ready at your fingertips without compromising restore speeds. We ran several tests to characterize the Archive drive's limits. In our single-drive synthetic tests measuring burst speeds, the Archive HDD ran close to its cousin, the Seagate Enterprise 6TB, in 2MB sequential transfer. In the 2MB random transfer the HDD had the fastest write speeds at 109MB/s. In our 4K random transfer the drive again had the fastest write speeds at 10.5MB/s. Its 4K throughput was the highest for write at 2,693 IOPS and it had an impressive average latency at 0.37ms. Switching over to single-drive sustained synthetic benchmarks we see the Seagate Archive HDD make a sharp change in performance. SMR drives are designed to work well in short burst write activity. Sustained write performance in this case is a weakness that we see throughout the rest of our tests. The Archive HDD’s read performance was on par, and even ahead of, the other drives tested. In the 4K tests, the drive had performance of 138 IOPS in throughput, an average latency of 1,839.62ms, a max latency of 5,088ms, and a standard deviation of 499.25ms. The write performance numbers were, unsurprisingly, far below the results of the other drives. With our 8K 70% Read 30%, the Archive HDD again tested at the bottom of the group. The 128K large block sequential showed pretty good results however, with speeds of 195MB/s read and 194MB/s write. It should be noted though that the FIO results do not match the Veeam application testing where the sustained writes were much lower.  Even though Seagate doesn't recommend these drives in RAID groups, we ran a NAS synthetic workload analysis using a Synology DiskStation DS1815+ and checked the performance of both iSCSI and CIFS configurations for the Seagate Archive HDD 8TB in RAID10 mode. With the low cost of the Archive drives, we're seeing gadget blogs and others recommending them for NAS environments. The results for the NAS synthetic analysis is very similar to the sustained synthetic benchmarks in overall placing of the Archive HDD, the read performance was on par with the other drives while the write performance was often lagging. In these tests, CIFS configurations did result in better results for write numbers. The Archive posted 4K throughput read results of 514 IOPS (CIFS), 2,067 IOPS (iSCSI), and average read latencies of 497.07ms (CIFS) and 123.84ms (iSCSI). Again the Archive HDD was at the bottom of the pack in the 8K 70% Read 30% Write tests. Our 8K 100% Read/Write test the drive had a read throughput of 47,255 IOPS (CIFS) and 25,340 IOPS (iSCSI), over twice as high as the runner up. And finally in our 128K large block sequential test showed read speeds of 463MB/s (CIFS) and 193MB/s (iSCSI). More concerning though about using the drives in RAID is rebuild time. In a simple RAID1 group of two drives, the Archive took over 57 hours to rebuild while the NAS was idle. An 8TB PMR drive took a bit under 20 hours.  Ultimately the Seagate Archive 8TB HDD has a lot of legs in very specific use cases. As a single drive it's fine, if the use case can tolerate slower sustained writes. With burst writes and reads, the drive performs very well. In pooled storage, the drive really belongs in a more sophisticated object store. Traditional software or hardware RAID is simply not recommended due to the sustained write penalty that occurs during rebuild. Admins can also get creative, like our Veeam backup test. Using 8 drives we managed to get 64TB raw backup target, with RAID1-style parity. It would be easy to get even more sophisticated for additional data protection. In such cases where cost/TB is a big driver in the decision process, the Archive drive comes in very handy.
