Seagate NAS HDD Review 8TB

Seagate NAS HDD Review 8TB

A few weeks back we took a look at an Enterprise class drive from Seagate, designed to offer massive storage capacity in that environment. Not everyone needs Enterprise class support/features though so as expected Seagate have also started to offer a similar drive for home and small office users to install in their NAS, or server, and today we take a look at that in our Seagate NAS HDD Review 8TB.

Seagate NAS HDD Review 8TB – The Drive

seagate-nas-hdd-review-8TB seagate-nas-hdd-8tb-review-drive

Our sample of the NAS HDD 8TB arrived in a plastic protective case, we would assume that retail models will arrive in some more flashy packaging but either way you can be sure Seagate will package it appropriately to arrive in perfect condition.

In terms of look and feel, this is certainly a drive with a bit of weight to it (780g) however the dimensions are the same as any other standard HDD (26.11 x 101.6 x 146.9mm). So its a 3.5″ form factor and our only point of note is that there are only two screw holes on the side, some drive bays make use of the “missing” third/middle hole, so just be sure to check there are no parts that need removed from your bay before dropping in the drive.

Finally from an external point of view the NAS HDD uses a standard SATA data and power connector.

When it is formatted (using Windows as an example) it has a total storage capacity of 7.27TB and Seagate note that the rated speeds are in excess of 210mb/s with power use peaking at 9w (7.2w idle, 0.6w sleep). Our cache level is 256MB and acoustic rating is 2.6bels in operation. As far as reliability goes, the MTBF rating is 1 million hours and the drive is rated for 180TB/year workload rate limit.


What makes this a NAS HDD rather than a generic one? These drives have firmware tuned for NAS operations and are tested with the leading brands of NAS, including Synology, Qnap, ASUSTOR, Thecus and Seagate. They are optimised for high workloads and contain error recovery tech to ensure minimal chance of a RAID rebuild being required. They also support multiple power profiles which are suited to 24×7 operation and have enhanced vibration tolerance which is ideal when multiple units are installed in a small NAS chassis.

Seagate NAS HDD Review 8TB – Software


The drive is compatible with SeaTools, an application from Seagate which allows us to monitor and maintain our drive over time.

As an added bonus the NAS HDD is also available with Seagate +Rescue Data Recovery Services. This 3-year plan allows us to send the drive to Seagate for data recovery. They note that have a success rate of nearly 90% and can work with:

  • RAID controller failure
  • Lost RAID configuration
  • Accidental reconfiguration
  • Accidental re-initialisation of the RAID array
  • Power surges that cause multiple drive failures simultaneously
  • Missing RAID partitions
  • Reformatted RAID partitions
  • Virus damage
  • Natural disaster, human error and drive failures

Seagate NAS HDD Review 8TB – Performance

Intel Core i7-5960X, ASRock X99 OC Formula, 4x4GB DDR4, Windows 10 64Bit.


On paper the NAS HDD is a little slower than the Enterprise model, approximately 210mb/s vs 240mb/s however our sample easily exceeded the paper specs and looking back at the Enterprise results we see that the standard version is a touch faster in peak performance. Both drives are of course exceptionally fast mechanical models.

Seagate NAS HDD Review 8TB – Conclusion

Options are always a good thing and that is exactly what the NAS HDD offers us. There are certainly environments where the Enterprise features and extended warranty will be useful but for most consumers the NAS HDD will be more than enough. 3-years is the warranty length and it is great to see that the drive can be covered by the same data recovery plan as the Enterprise model giving us as much peace of mind as possible.

We also get a firmware tuned for NAS operation, solid build quality and some very impressive read/write speeds, nearing 250mb/s. Key to the drive’s appeal though is that it is specifically designed to perform well, be reliable and fully supported in all key brands of NAS. Looking at the Seagate documentation alone we have a number of quotes from Synology, Qnap etc which sets the tone but more importantly, in our own experience, the NAS HDD worked flawlessly in a range of NAS devices from Synology, Qnap, Thecus and ASUSTOR. It also worked without issue on our Windows desktop build.

Available from Ebuyer and Newegg.

    I just received an seagate 8tb NAS HDD and now i’m looking at getting a NAS. I was looking at a 4-bay seagate NAS, however, I know that some NASs have a limit on the capacity of each bay. So I was wondering if an 8tb would still work if the NAS had a capacity of 6tb per bay?
