Specifications and Feature Set Comparison
Prior to getting into the performance evaluation, we will take a look at the specifications of the 6 TB Seagate Enterprise NAS HDD and see how it compares against the other NAS-specific hard drives that we have looked at before. As mentioned in our launch coverage, the Enterprise NAS HDD takes the hardware guts from the Enterprise Capacity v4 drives and firmware features from the NAS HDD line. The hardware aspects (such as the rotational speed, cache size, URE ratings etc.) come from the Enterprise Capacity v4. The table below presents the data for the drive against the others in our evaluation database.
|Comparative HDD Specifications|
|Interface||SATA 6 Gbps||SATA 6 Gbps|
|Sector Size / AF||512E||512E|
|Rotational Speed||7200 RPM||7200 RPM|
|Cache||128 MB||128 MB|
|Rated Load / Unload Cycles||600 K||600 K|
|Non-Recoverable Read Errors / Bits Read||< 1 in 1015||< 1 in 1015|
|MTBF||1.2 M||1.2 M|
|Rated Workload||180 TB/yr||180 TB/yr|
|Operating Temperature Range||5 to 60 C||5 to 60 C|
|Acoustics (Seek Average - dBA)||27 dBA||27 dBA|
|Physical Parameters||14.7 x 10.19 x 2.61 cm; 780 g||14.7 x 10.19 x 2.61 cm; 780 g|
|Warranty||5 years||5 years|
|Price (in USD, as-on-date)||$TBD||$TBD|
A high level overview of the various supported SATA features is provided by HD Tune Pro.
We get a better idea of the supported features using FinalWire's AIDA64 system report. The table below summarizes the extra information generated by AIDA64 (that is not already provided by HD Tune Pro).

nathanddrews - Wednesday, December 10, 2014 - linkWhat's the status of this drive's APM setting? Do the heads park frequently and make a lot of clicking noises? Can you enable/disable it using the driver or something like HDParm? Lately I've been less trusting of Seagate's HDDs because they don't allow user-controlled APM settings on many of their models. I have sufficient cooling in my rack, but half the drives I have are firmware locked with aggressive APM.
Samus - Wednesday, December 10, 2014 - linkAfter reading the review, I'd probably go for the Hitachi HE6 if these drives were priced close together. The feature set and more advanced nature of the Hitachi make it more attractive. I get that whole "not tried and true" helium technology argument, but the warranty is the same.
cm2187 - Wednesday, December 10, 2014 - linkI've read somewhere that the HGST Deskstars 6TB will be released soon. If they live by their predecessors, it's probably a more reliable substitute for the WD Red without the cost of the Seagate drives.
Samus - Wednesday, December 10, 2014 - linkI agree. Hitachi drives are excellent. If price isn't a factor (they're all the same price) then it's a no brainer.
Laststop311 - Thursday, December 11, 2014 - linkOh yea, after seeing the prices $420 for the seagate nas is only $30 cheaper and you'll make the 30 dollars back in power savings over the life of the drive. And the enterprise seagate is $50 more! They also consistently fail to mention that the He6 has less turbulence and friction from the platters spinning in a less dense environment. Less turbulence = less vibration and less vibration = less acoustic output. Also because of the helium environment the motor that spins the drive is slightly less powerful than standard motors since it uses less energy to spin platters inside helium versus air. Less powerful motor also means less vibrations from the motor. It's the quietest 7200 rpm 6TB HDD without a doubt.
Laststop311 - Wednesday, December 10, 2014 - linkYeah like I've said before in 20+ years of using a PC I still do not have 1 dead hitachi drive in my possession. I've probably bought 8 or so hitachi drives in my life and they are flawless. I've had 5 Seagates break and 3 were from the same rma process like the drive that replaced the broken one broke then broke again thats how bad they are. Western Digital isn't that bad I've only had 1 of those ever break on me. Haven't had much experience with Toshiba tho.
Laststop311 - Wednesday, December 10, 2014 - linkYeah so forgot, I totally recommend the He6. I have a hard time believing the listed acoustics for the 2 drives. Seagate says their drive is 27db and the He6 is 29db. I rly highly doubt the seagate is quieter the Helium environment produces less friction and less turbulence because helium is less dense than air. Friction and turbulence causes vibration and is a huge source of HDD noise. The He6 should be the quietest 6TB 7200 rpm drive. Also tho the He6 lacks maximum transfer speed it makes up for it with the lowest latency by a good 2-3 milliseconds. So the He6 ends up feeling more snappy even tho its lower max transfer speed.
Laststop311 - Wednesday, December 10, 2014 - linkJust some data to backup my claim backblaze is a cloud storage company that tracks it's hard drive failures.
What you will see there is exactly my same experience. Hitachi has barely any failures, Seagate has a huge amount of failures way beyond every 1 else and western digital is a little worse than hitachi but better than seagate.
Laststop311 - Thursday, December 11, 2014 - linkAnd another thing. You can almost guarantee Hitachi has at the very least an 8TB He8 to compete against Seagates new 8TB drive waiting in the wings going through its last QA testing. If Hitachi can blend the extra platter density from helium and the extra density per platter in shingled recording being used in Seagate then they could easily blow past 8TB and make 10TB and 12TB drives as well. The helium Hitachi drive is without a doubt the most advanced hard drive platform on the market.
And for massive deployments like a cloud storage service would need, the energy savings from the He6 can end up saving a lot of kWh on your power bill. But even for a home user it's nice to shave off as many watts as possible from your system without affecting performance, thats why 80+ platinum sells even tho it's only microscopically better than 80+ gold.
ddriver - Wednesday, December 10, 2014 - linkToo bad you cannot put in a review the one thing that truly matters - reliability...
