Data storage requirements have seen an exponential increase over the last several years. Despite SSDs taking over the role of the primary drive in most computing systems, hard drives continue to shine in areas requiring storage of large amount of data. Hard drives are also suitable for workloads that are largely sequential and not performance sensitive. SSDs are yet to achieve the low $/GB metric that makes HDDs attractive in that market segment. Modern games run into 100s of GBs in terms of install size. As flash prices continue to stay high, high-capacity SSDs have tended to carry a significant premium. In this scenario, the gaming crowd may find hard drives attractive. This guide will help readers choose the appropriate hard drive based on their workload, while also keeping the price factor in mind.

There are three active vendors in the consumer hard drive space - Seagate, Toshiba, and Western Digital. While Seagate and Toshiba offer hard drives targeting desktop workloads at their leading capacity points, Western Digital reserves the leading edge for enterprise and NAS drives. As of today, Toshiba's highest capacity hard drive for the power user / NAS market is only 8TB. Western Digital has 10TB drives, while Seagate has 12TB ones. Toshiba's 8TB offerings (the N300 and the X300) didn't make it to our testbed in time for this guide. With a focus on comparison of metrics for the purpose of recommendation, we restrict our options pool to the following drives:

  1. Seagate BarraCuda Pro 12TB
  2. Western Digital Red Pro 10TB
  3. Seagate BarraCuda Pro 10TB
  4. Seagate IronWolf NAS 12TB
  5. Seagate IronWolf NAS 10TB
  6. Western Digital Red 10TB

Device Characteristics and Firmware Features

HD Tune Pro provides us a quick look at the supported SATA feature set of the drives. We find that the Western Digital drives offer features such as advanced power management and host protected areas.

Drive Information

The WD Red also has a spindle speed of 5400 RPM compared to 7200 RPM in other drives. This lower spindle speed is also responsible for its excellent power consumption profile.

Performance Benchmarking with HD Tune Pro

The first set of benchmarks that we look at is from HD Tune Pro. The program allows us to test different workloads. They make it clear as to how the performance would vary as the drive gets filled up. In particular, we can see significant difference when the area being accessed is on the outer side of the platter compared to the points closer to the center.

Sequential Read / Write Benchmark

Out of all the considered drives, the BarraCuda Pro 12TB version performs the best. At the 10TB point, both the BarraCuda Pro and the Red Pro perform similarly. The 5400 RPM speed of the Red puts it in the last place.

Random Access Benchmarks

In the random access benchmark, the WD Red Pro comes out better than the BarraCuda Pro. In general, the WD drives give more IOPS compared to the Seagate ones.

Miscellaneous Hard Drive-Specific Tests

The behavior in the extra tests is similar to what we observed in the random access tests. The key takeaway here is that Seagate wins out on the sequential front, but, the WD is slightly more optimized for random accesses also.

Performance Benchmarking with Custom Tests

The previous subsection dealt with artificial workloads. We also have results from our custom evaluation routine - robocopy benchmarks with performance consistency checks as well as the PCMark 8 storage workloads.

The most common usage scenario for high-capacity SATA hard drives in a desktop or direct-attached scenario is the transfer of large amounts of photos and videos to and from the unit. The minor usage scenario is importing files directly off the drive into a multimedia editing program such as Adobe Photoshop.

In order to tackle the first use-case, we created three test folders with the following characteristics:

  • Photos: 15.6 GB collection of 4320 photos (RAW as well as JPEGs) in 61 sub-folders
  • Videos: 16.1 GB collection of 244 videos (MP4 as well as MOVs) in 6 sub-folders
  • BR: 10.7 GB Blu-ray folder structure of the IDT Benchmark Blu-ray

Photos Read

For the second use-case, we take advantage of PC Mark 8's storage bench. The storage workload involves games as well as multimedia editing applications. The command line version allows us to cherry-pick storage traces to run on a target drive. We chose the following traces.

  • World of Warcraft
  • Battlefield 3
  • Adobe Photoshop (Light)
  • Adobe Photoshop (Heavy)
  • Adobe After Effects
  • Adobe Illustrator

Usually, PC Mark 8 reports time to complete the trace, but the detailed log report has the read and write bandwidth figures which we present in our performance graphs. Note that the bandwidth number reported in the results don't involve idle time compression. Results might appear low, but that is part of the workload characteristic.

World of Warcraft Read

We find that the Seagate BarraCuda Pro 12TB comes out on top for the gaming access traces, as well as all other read-intensive scenarios. The WD Red Pro takes the lead in some of the write scenarios.

Performance Consistency and Thermals

Yet another interesting aspect of these drives is performance consistency. In order to get an idea of relative power consumption as well as the thermal characteristics, we instrumented our robocopy DAS benchmark suite to record the hard drive's read and write transfer rates while the robocopy process took place in the background. We also recorded the internal temperature of the drive during the process. The graphs below show the speeds observed during our real-world DAS suite processing. The first three sets of writes and reads correspond to the photos suite. A small gap (for the transfer of the videos suite from the primary drive to the RAM drive) is followed by three sets for the next data set. Another small RAM-drive transfer gap is followed by three sets for the Blu-ray folder.

Performance Consistency and Thermal Characteristics

As expected, the WD Red shows the minimum temperature rise / lowest power consumption, but, it also takes the longest to complete the benchmark. The Seagate BarraCuda Pro 12TB performance well overall. However, at the 10TB capacity point, the WD Red Pro gets the edge over the Seagate BarraCuda Pro 10TB version.

Concluding Remarks

Analyzing the results of our evaluation indicates that different vendors optimize the firmware of their units for different use-cases. Therefore, each of the top drives manages to excel in one workload or the other. Before going to the recommendations, it is helpful to have a look at the pricing for the models.

Consumer Hard Drives - Pricing (as on 24th Nov. 2017)
Drive Model Number Capacity (GB) Street Price (USD) Price per GB (cents/GB)
Seagate IronWolf 10TB ST10000VN0004 10000 300 3.00
Seagate IronWolf 12TB ST12000VN0007 12000 400 3.33
Seagate BarraCuda Pro 10TB ST10000DM0004 10000 360 3.60
Seagate BarraCuda Pro 12TB ST12000DM0007 12000 460 3.83
Western Digital Red 10TB WD100EFAX 10000 395 3.95
Western Digital Red Pro 10TB WD101KFBX 10000 450 4.50

The Seagate IronWolf 10TB is the best value for money. The Seagate BarraCuda Pro 12TB version gets our recommendation for the best performing consumer hard drive for gaming desktops and direct-attached-storage units. The WD Red Pro 10TB also performs very well, but carries premium pricing (due to its NAS focus). We recommend it for content creation desktops. The WD Red 10TB is the best choice for scenarios where low power consumption is essential.

    No WD Gold 10TB or 12TB? 12TB is definitely available. 10TB Gold is often cheaper than Red Pro. Reply

    Gold is Enterprise, not Consumer.

    I do want to add Enterprise benchmarks to our dataset.. in due course, hopefully.

    Let's be honest here. Anything past 4 or 6 TB is waaay over what most consumers will be using. The 12 Tb ones are just plain Prosumer territory. Reply

    SMH! Seagates are garbage!! A lot of my friends have had problems with Seagate drives. I recently bought a Seagate cause I didn't believe them and it failed in 7 days!! I'll never buy another Seagate again!! Reply

    I can say exactly the same about Western Digital :) Exactly !

    The truth is that since we are left with this de-facto duopoly, they don't care anymore.

    Drive failure rated went from 2% to 27% in some cases.

    This is were no competition gets us.

    Any drive can fail.. Once you accept that and establish a reliable and automatic backup strategy, Seagate drives are just fine. Reply

    Hi there, long time reader of anandtech here. I appreciate that a lot of time and work was spent on making this article and it is most certainly informative and all. That being said, I am pretty sure that as an average consumer, I most definitely would not be needing a 10TB drive that costs $300. Please either change the title of the article or review true consumer drives such as the WD Blacks/Blues and BarraCudas. Keep up the good work and quality, thank you. Reply
  • JWatson - Saturday, November 25, 2017 - link

    I gotta agree with daytona675. Most consumers are NOT willing to spend $300 or more on a single spinning hard drive. On the other hand, people are willing to spend $130-160 on an 8TB external drive which can then be "shucked" for the drive inside.

    Case in point is the 8TB Western Digital External deal for Black Friday which contains a 8TB WD Red NAS drive ($160) or a white labeled version for only $130 (before taxes) which more likely for consumers to buy. That's $0.02/GB (or less) and still has decent performance! Why even bother spending 300 dollars when I can get 16TB for nearly the price a single 10TB drive as a consumer? Enterprises and businesses this wouldn't work, but as a consumer it sure does.

    Agreed. I'm waffling about a similar deal here (Canada) for Seagate 8T externals). I'm reluctant because shingled drives scare me. I came to this article to get my fear in perspective. I remain uninformed.

    The Seagate 8T externals are shingled, even though the specs are silent on this. I expect the WD ones are too, but haven't looked into this.

    Oh, and RAID on 8T drives seems crazy: regenerating an array after a failure takes so long that there is a too-significant likelihood of a second failure before redundancy is restored.
