For the longest time I ran a set of four Seagate Barracuda 7200.12's in my NAS here in the lab. These drives served me very well up until last year, when they were replaced by the purpose built WD Red NASWare drives. Now though Seagate has entered the purpose built drive market with the NAS HDD.

When you are in the market for a shiny new HDD, it's of utmost importance to take a few things into consideration including the purpose of the drive, the capacity you're looking for, and the most important, what environment the drive will be subjected to. I say the environment as the most important because drives like the NAS HDD are purpose built to run 24/7 in hot environments like that of a 1 to 5 bay NAS appliance. Drives like the previously reviewed Desktop HDD .15 are made for just that, your desktop PC, where there is a bit more airflow.

Now you may be saying to yourself, "this NAS HDD is just the Desktop HDD .15 with fancy firmware", and to an extent that could be true. Both drives utilize the same four platter design, with areal density at 625GB/ sq. in and the same 1*10^14 BER, but Seagate has added a few more improvements to the NAS HDD as well. Technology like Dual Plane Balance and Seagate's patented NASWorks Error Recovery Control increase the drives durability and vibration tolerance for the 24/7 environment of small NAS appliances. It's not just some fancy marketing talk.

If this isn't enough for you, the Load/Unload cycles for the NAS HDD have been doubled to 600,000 over the 300,000 found in the Desktop HDD .15, and adding to this the Power-On Hours, which sit at 8760, four times more than the Desktop HDD. Power consumption figures have also taken a dive with typical operating power going from 7.5 watts to 4.8 watts in the NAS HDD. The same is true for the idle and standby power as well where the Desktop HDD consumed five watts at idle and 0.75 watts in standby, the NAS HDD uses just 3.95 at idle and 0.5 in standby.

Specifications, Pricing and Availability

Taking a look at the specifications for the NAS HDD by Seagate, we find the cache listed as 64MB. Closely following this is the Max Sustained Transfer Rate of 180MB/s with the Power On to Ready at <17 seconds. Power consumption, which I covered in the intro sits at 4.8 watts during operation with idle and standby at 3.95 watts and 0.5 watts respectively.

The Load/Unload cycles have been boosted to 600,000, as have the Power On hours that now sit at 8760. The MTBF of the Seagate NAS HDD is listed at one million hours.

Newegg at the time of writing has the NAS HDD in the 4TB capacity listed and in stock at $209.99. Seagate offers a three year warranty on the NAS HDD.

The backside of the drive houses a green PCB. This PCB carried the same part number as the Desktop HDD .15 with the exception of the revision - the NAS HDD is using Rev. B.

Removing the PCB from the back of the drive, we get a closer look at the construction. A set of pins connect the drives platters and heads to the PCB.

Front and center we found the NAS HDD to use an LSI MCU. Just north of the MCU you will find the cache by Samsung, and to the right we have the VCU by Smooth.

Benchmarks - Anvil Storage Utilities

Anvil Storage Utilities

Version and / or Patch Used: RC6

So what is Anvil Storage Utilities? First of all, it's a storage benchmark for SSDs and HDDs where you can check and monitor your performance. The Standard Storage Benchmark performs a series of tests, you can run a full test or just the read or the write test or you can run a single test, i.e. 4K DQ16.

Anvil Storage Utilities is not officially available yet but we've been playing with the beta for several months now. The author, Anvil on several international forums has been updating the software steadily and is adding new features every couple of months.

The software is used several different ways and to show different aspects for each drive. We've chosen to use this software to show the performance of a drive with two different data sets. The first is with compressible data and the second data set is incompressible data. Several users have requested this data in our SSD reviews.

Incompressible Data

Resume from S4 Hibernation

Hibernation or S4 is part of the Advanced Configuration and Power Interface specification.

In our custom resume from S4 testing, the NAS HDD did quite well. Coming in at 7.75 seconds, it's well ahead of the WD Red that managed 16.6 seconds.

Final Thoughts

Seagate NAS HDD (ST4000VN000) 4000GB HDD Review 99 | TweakTown.com

Back in July of last year, Western Digital launched the first purpose built NAS hard drive, and for the longest time I was waiting for Seagate to do the same. Today this has come to fruition with the NAS HDD, offered in two, three and four TB capacities. With the launch of a 4TB model, Seagate has one upped WD when it comes to storage capacity with 20TB now being capable in a 5-bay NAS, and since the WD Red tops out at 3TB currently, it makes you wonder how long before WD announces their Red at 4TB.

I must admit, after receiving the press release for the NAS HDD, I thought this was just a rebadged Desktop HDD, but it's not. Seagate has taken much of what they have learned in the enterprise sector and applied it to a drive, which is in reach of the average consumer. We now have technology like dual plane balance and NASWorks that supports highly customized error recovery controls, power management and higher vibration tolerance catered just for the 24/7 high heat environment of your typical NAS appliance.

Performance of the NAS HDD was on par with the Desktop variant throughout most of our testing, and well ahead of the 1TB single platter WD Red NAS drive. Most notably the performance was a balanced effort between read and write speeds, this coming as a byproduct of Seagate's NASWorks technology.

At the time of writing pricing of the Seagate NAS HDD in the 4TB capacity is set at $209.99 with high availability. You will also find the 3TB and 2TB capacities listed at $169.99 and $139.99, respectively.

Growing up in a small farm town, tech wasn't around, unless it was in a tractor. At an early age, Tyler's parents brought home their first PC. Tyler was hooked and learned what it meant to format a HDD, spending many nights reinstalling Windows 95. Tyler's love and enthusiast nature always kept his PC nearby. Eager to get deeper into tech, he started reviewing.
