In our series of Hard Disk Drive guides, here’s the latest update to our list of recommended HDDs. All numbers in the text are updated to reflect pricing at the time of writing.

Best Consumer Hard Drives: August 2020

Data storage requirements have kept increasing over the last several years. While SSDs have taken over the role of the primary drive in most computing systems, hard drives continue to be the storage media of choice in areas dealing with large amount of relatively cold data. Hard drives are also suitable for workloads that are largely sequential and not performance sensitive. The $/GB metric for SSDs (particularly with QLC in the picture) is showing a downward trend, but it is still not low enough to match HDDs in that market segment. The consumer HDD market has not seen any new introductions since the release of our Q1 HDD guide. However, Western Digital did introduce their EAMR drives, with the 16TB and 18TB WD Gold enterprise models getting retail availability. The company also split their WD Red series of hard drives into the WD Red and WD Red Plus lines.

From a gaming perspective, install sizes of 100s of GBs are not uncommon for modern games. Long-term backup storage and high-capacity NAS units for consumer use are also ideal use-cases for hard drives. The challenge in picking any hard drive, of course, is balancing workload needs with total drive costs. Most consumers inn a non-business settings also require low-power and low-noise, yet, high capacity drives. Our guide has an explicit suggested option for that scenario also.

August 2020 HDD Recommendations

High-Capacity Desktop 14TB Seagate BarraCuda Pro $515
14TB Toshiba X300 $566
Mid-Capacity Desktop 6TB Seagate Exos Enterprise $185
High-Capacity NAS 16TB Seagate Exos X16 $372
Cost-Effective High-Capacity NAS 14TB Seagate Exos X16 $348

There are three active vendors in the consumer hard drive space - Seagate, Toshiba, and Western Digital. While Seagate offers hard drives targeting consumer workloads at their leading capacity points, Western Digital and Toshiba reserve the leading edge for enterprise and datacenter drives.

Consumers looking to purchase hard-drives need to have a rough idea of the use-cases they are going to subject the drives to. Based on that, a specific set of metrics needs to be considered. We first take a look at the different metrics that matter, and how various hard drives stack up against each other. Since many hard drive families from different vendors can satisfy the requirements, it may all come down to the pricing. We will present a pricing matrix for various hard drive families against the available capacities.

For our guide, we're narrowing down the vast field of hard drives to the following models/families. In particular, we are excluding surveillance-focused drives such as the WD Purple or Seagate SkyHawk, since these drives are based on the same technology, but often carry a price premium. Meanwhile, we're also making sure to include some of the enterprise / datacenter SATA drives that are available for purchase from e-tailers, as these sometimes offer some great deals in terms of capacity-per-dollar.

  1. Seagate BarraCuda Pro
  2. Seagate IronWolf NAS
  3. Seagate IronWolf Pro NAS
  4. Seagate Exos Enterprise
  5. Toshiba N300
  6. Toshiba X300
  7. Western Digital Gold
  8. Western Digital Red
  9. Western Digital Red Plus
  10. Western Digital Red Pro

A few notes are in order - the WD Ultrastar DC lineup which used to be in our earlier guides is not widely available in the North American retail market. We have replaced it with the WD Gold series. Toshiba's MG08 series includes a 9-platter 16TB CMR model. However, it is again enterprise-focused, and the retail market has to make do with the N300 and X300 drives for NAS and desktop systems. That said, the specifications are very similar, as we noted in the launch article for the 9-platter drives.

Metrics that Matter

One of the easiest ways to narrow down the search for a suitable hard drive is to look at the target market of each family. The table below lists the suggested target market for each hard drive family we are considering today.

Hard Drive Families - Target Markets
Drive Family Target Markets
Seagate BarraCuda Pro Desktops and All-in-Ones
Home Servers
Creative Professionals Workstations
Entry-Level Direct-Attached-Storage (DAS) Units
Seagate IronWolf NAS NAS Units up to 8 bays
(Home, SOHO, and Small Business)
Seagate IronWolf Pro NAS NAS Units up to 24 bays
(Creative Pros, SOHO, and Small to Medium Enterprises)
Seagate Exos Enterprise Datacenter and Bulk Cloud Storage
Toshiba N300 NAS Units up to 8 bays
Toshiba X300 Professional Desktops, Home Media or Gaming PCs
WD Gold Datacenter and Bulk Cloud Storage
WD Red NAS Units up to 8 bays, Read-Intensive and Archival Workloads
WD Red Plus NAS Units up to 8 bays
WD Red Pro NAS Units up to 24 bays

After filtering out models that don't apply to your use-case (as an example, for usage in a 4-bay NAS enclosure, one could rule out the Tosiba X300 straight away), we can then take a look at how the specifications of various drive families compare.

Hard Drive Families - Metrics of Interest
Drive Family Rated Workload (TB/yr) Rated Load / Unload Cycles Unrecoverable Read Errors MTBF (Hours) Warranty (Years)
Seagate BarraCuda Pro 300 300K 1 in 10E15 1.0M 5
Seagate IronWolf NAS 180 600K 1 in 10E15 1.0M 3
Seagate IronWolf Pro NAS 300 600K 1 in 10E15 1.2M 5
Seagate Exos Enterprise 550 600K 1 in 10E15 2.5M 5
Toshiba N300 180 300K 1 in 10E14 1.0M 3
Toshiba X300 N/A (72?) 300K 1 in 10E14 0.6M 2
WD Gold 550 600K 1 in 10E15 2.5M 5
WD Red 180 600K 1 in 10E14 1.0M 3
WD Red Plus 180 600K 1 in 10E14 1.0M 3
WD Red Pro 300 600K 1 in 10E14 1.0M 5

Based on these metrics, it is clear that the enterprise drives (Seagate Exos Enterprise and WD Gold) are rated to be more reliable in the long run over a big sample set. However, most consumer use-cases do not need a 550 TB/yr workload rating. 180 - 300 TB/yr workload rating is plenty reasonable for most users when the drives are going to be used as part of RAID arrays.

The BarraCuda Pro strikes a nice balance across many metrics, but it is rated only for 300K load / unload cycles. It also doesn't have the RV sensors present in the rest of the drives (other than the Toshiba X300).

In considering the non-enterprise drives, we note that the 'Unrecoverable Read Errors' metric is 10x worse for the WD and Toshiba drives compared to the Seagate ones. The MTTF metric for the IronWolf Pro is slightly better than the other drives (at 1.2M vs. 1M hours).

One of the aspects not mentioned in the above table is that the WD Red and Red Plus drives are in the 5400 RPM class, while the rest are all 7200 RPM. From a raw performance perspective at equivalent capacity points, these might not win on benchmarks, but, it is likely to be the most power efficient and have the best noise profile of the lot. Another aspect to be kept in mind is that the WD Red line is now exclusively SMR-based, with the CMR drives moving to the WD Red Plus line. Unless the consumer is technically savvy enough to understand the pitfalls of SMR and its applicability to the desired use-case, the SMR-based WD Red line is best avoided.

Pricing Matrix and Concluding Remarks

The matrix below shows the current pricing for each available capacity point in all the considered hard drive families.

Cheapest Drives in Bold, AT-recommended Drives In Green
Drive Family 18TB 16TB 14TB 12TB 10TB 8TB 6TB

The desktop storage market is a straight shoot-out between the Seagate BarraCuda Pro and the Toshiba X300 with both vendors competing in the key areas. For 12 TB and below, Toshiba consistently beats Seagate's pricing at every capacity point. That said, the higher capacity versions of the Toshiba use 9 platters, and consume more power compared to the corresponding BarraCuda Pro. The Seagate pricing also includes data recovery service during the warranty period. For the extra cost, we get a much higher workload rating, better reliability, and three extra years of warranty. So, this is a case where the benefits outweigh the cost, and our recommendation goes to the costlier of the two drives – the Seagate BarraCuda Pro, though the X300 might also be considered if one has hard budget limitations for mid-rage capacities. In certain cases, the low price of the Seagate Exos drive may make it suitable for desktop usage also.

 

Prior to commenting on the other possible use-cases, one thing is clear from the above pricing matrix - if you absolutely require 18TB per disk, the WD Gold is your only choice for purchase in the retail market. We expect Seagate 18TB drives to appear in the retail market soon (at least in the Exos avatar), but till then, there is not much choice for the consumer)

On the SOHO / SMB NAS front, the Seagate Exos series, despite its enterprise background, continues to make a strong case across multiple capacity points. The only places where the WD Red could edge out as a better choice are scenarios where the power consumption needs to be kept low. The 6TB WD Red is also the lowest-priced 6TB currently in the table. The IronWolf NAS models deliver slightly better performance compared to the WD Red due to the 7200RPM nature, but, have correspondingly higher power consumption numbers. On the SMB / SME NAS front, the WD Red Pro has started reaching better price points compared to previous quarters. While the 14TB and 8TB versions are costlier than the IronWolf Pro, the WD Red Pro edges out the Seagate offering by wide margins at other capacity points. However, the bundled data recovery service must be considered in the IronWolf Pro pricing.

Based on the above analysis, the recommendations for the NAS drives are clear - WD Red when performance is not as important as overall power consumption and low noise profile, and the Seagate Exos Enterprise drives otherwise. This is assuming that the user has adopted the 3-2-1 backup rule and doesn't foresee the need for a data recovery service (DRS). The IronWolf Pro NAS and the BarraCuda Pro both bundle the DRS. This needs to be taken into account while considering the pricing difference against other drives in the same capacity class.

 
 

Finally, a note on shucking – buying a relatively cheap external hard disk (such as the 14TB Western Digital Elements with a re-labeled WD Red variant drive inside for $260), removing the internal drive, and using it in a NAS or as an internal desktop drive in the place of a more costly drive ($449). While this is easy enough to do, the user experience might not be optimal - obtaining warranty services is pretty much ruled out, the default TLER settings might need alteration (which is not always possible with commercial off-the-shelf NAS units) and so on. We believe this is not worth the trouble for most readers unless the money spent is to be treated as sunk cost, and the drive is going to be used in non-critical scenarios.

    Unless this has changed very recently, only the lower-capacity WD Reds are SMR. Anything 8TB and above is still CMR. Reply
  • MrVibrato - Thursday, August 27, 2020 - link

    No. _All_ WD Red's are SMR. WD rebranded all non-SMR Red's as "Red Plus". But then again, i don't really care anymore after the stunt and subsequent weaseling when directly asked whether certain Red's are actually SMR. Until it all blew up in their faces. What do they say: Once bitten, twice shy... Reply
  • Lezmaka - Thursday, August 27, 2020 - link

    No. There are still plenty of WD Red drives for sale in the 2-6TB range out in the wild at places like NewEgg and Amazon that are _not_ SMR and are still called just WD Red. At some point after those drives are no longer available, it'll be true that WD Red = SMR but not yet. Reply

    Hitachi all the way. Either buy some old 4TB Coolspins or go with He6's. Fast, reliable, cheap, no worry about SMR BS. Reply

    All NEW non-SMR reds are rebranded as Red Plus. The point of Lezmaka below is that one still needs to watch out when shopping for Reds because many stores may have unsold inventory of SMR and CMR drives mixed under the same Red name. WD has created such a big mess with this, instead of just being transparent from the beginning.

    Does it even matter? Slower than SSDs is all we will get. LOL Reply

    Consumer hard drive article contains enterprise hard drives AND Anandtech does not have any supporting data for these drives in the form of reviews so you can just write off this article as a filler that lacks useful information and move on with life. Reply

    You want to know how you know "NAS"-branded HDDs are pure C-rate, beta HW, overpriced scams? Besides WD's SMR scandal (lawsuit pending):

    The Seagate Exos Enterprise drive (with longer MTBF and higher rated workload) is cheaper than the Ironwolf Pro at 8 TB, 10 TB, 12 TB, 14 TB, and 16 TB.

    The highest-end Seagate enterprise 3.5" drive is cheaper than Ironwolf Pro at every single capacity. Ironwolf Pro is a marketing phenomenon.

    Source, from B&H Photo as an authorized dealer: https://www.bhphotovideo.com/c/products/Internal-D...

    Same price order applies on Amazon & Newegg (as Anandtech's chart shows), but some of those links use non-warrantied sellers, so B&H Photo's pricing really drives the point home.

    *every single capacity except 4/6 TB.

    Is the bundled data recovery service..really worth that much? What's the success rate here?
