A Brief History on Seagate and Western Digital

Let‘s first quickly travel through time and see how these storage giants came into existence before we pit their products head-to-head!

Seagate began in 1979 in Scotts Valley, California as "Shugart Technology". Founder Alan Shugart led the company‘s growth, becoming an early supplier of 5.25-inch HDDs.

In the 90s and 2000s, Seagate consolidated through various acquisitions of competitors like Conner Peripherals, Maxtor and Samsung‘s HDD business. This propelled Seagate into the #1 hard drive vendor spot in market share by 2006.

Currently headquartered in Dublin, Ireland and Cupertino, California, Seagate ships around 160,000 drives daily powering consumer devices, data centers, surveillance solutions and more.

Western Digital (WD) was born in 1970 in Irvine, California, founded by storage industry veteran Alvin B. Phillips. WD found initial success selling controllers for HDDs and introduced their first disk drive in 1988.

Through subsequent takeovers of competitors like HGST, WD steadily expanded capabilities to become Seagate‘s archrival in HDDs along with SSDs, flash drives and other storage gear.

WD ships over a million hard drives daily from global manufacturing facilities in US, Asia and Europe. WD also produces memory products after acquiring SanDisk in 2016.

In recent years Seagate and WD account for 60-70% combined market share in HDD shipments, with Toshiba distant third around 17%.

Battle of the Specs: How Seagate and WD Compare

Now that we know a bit of history behind both the HDD giants, let‘s study how they fare across various performance parameters:

Specifications Seagate Western Digital (WD)
Storage Capacities
  • Up to 16TB capacity per disk
  • Up to 14TB currently per disk
Drive Speed – Mainly 7200 RPM drives
– Some 5400 RPM also available
– 5400, 7200 AND 10000 RPM drives available
– Wider variety of speed options
Cache Buffer – Up to 256MB cache
– Lower cache for entry models
– Up to 512MB cache
– More cache across lineup
MTBF Ratings
  • 1M hour rating typical
  • Up to 2.5M hour rating
  • Higher lifespans forecast
Workload Limits
  • Up to 300TB per year
  • Up to 550TB per year
  • Better suited for demanding environments
  • Typically 2-3 years
  • Typically 3-5 years
  • Some models even longer
Price Per TB
  • Tend to be more affordable
  • Slightly pricier in terms of $/TB

With the battle lines drawn across various parameters, let‘s analyze where each brand pulls ahead or lags behind.

#1 Storage Density: Seagate Edges Ahead

As you can observe from the table, Seagate currently enables higher peak storage capacity reaching up to 16TB in their flagship models.

So if you truly need to maximize capacity without adding more physical drives, Seagate wins by a hair. Those 2 extra terabytes can mean 25%+ more storage room for critical data.

However, 16TB is close to the limits for current perpendicular magnetic recording (PMR) approach used to store data on spinning platters. So until new techniques like shingled magnetic recording (SMR) mature, both WD and Seagate‘s capacities will hover around these levels.

#2 Drive Speed Variants: WD Takes the Crown

While Seagate primarily sticks to the usual 5400 RPM (lower power drives) and 7200 RPM (mainstream desktop drives) models, Western Digital offers faster 10,000 RPM high speed options.

So for users needing to minimize access times while avoiding the premium cost of SSDs, WD‘s 10K Velociraptor family hits the sweet spot. The lower rotational delay pays off in tasks involving heavy random access like complex 3D modeling, video editing etc.

For typical usage, both brands 7200 RPM drives are on par. But WD‘s faster spindle speeds cater to buyers looking for a performance boost beyond what baseline HDDs can muster.

#3 Lifespan and Reliability: WDedges Ahead..Barely!

Reliability is perhaps what consumers care about the most while choosing long term storage. After all nothing compares to the heartache of sudden drive failures causing permanent data loss!

Here‘s what I found after comparing multiple sources:

While a fraction of drives from both manufacturers get sent for recovery, it suggests WD enjoys a small but meaningful reliability edge.

You‘ll also observe from the spec table that WD forecasts over 2X longer lifespans with MTBF (Mean Time Between Failures) ratings reaching up to 2.5 million hours for some enterprise class models way beyond the 1M hours from Seagate. And max workload limits too run higher indicating design headroom buffer beyond standard usage.

But average consumers using drives in maintained environments seldom reach such extreme workloads. And perfectly normal drives from both brands do fail prematurely for reasons beyond manufacturing defects – shock, thermals, firmware bugs etc.

So when looking at typical failures rates around 1-2% annually, either company‘s drives with proper usage care should keep your data safe for 3+ years on average. But it seems WD‘s tighter quality controls give them an edge resulting in lower observed failure incidents.

Real-World Performance Benchmarks

Let‘s move beyond spec sheet wars and see actual usage experience you can expect!

Tom‘s Hardware ran Throughput benchmarks consisting of realistic read-write loads between:

  • Seagate‘s latest generation FireCuda 520 SSHD 2TB drive with SSD caching
  • WD‘s flagship BLACK 750 NVMe SSD 1TB

Seagate vs WD real world benchmarks

The Seagate FireCuda 520 combines a hard drive‘s storage capacity with SSD-like performance thanks to it‘s onboard flash caching. And we can see it edging out WD‘s pure SSD in heavier Load and IO intensive tests!

But WD‘s SSD maintained faster peak sequential Read/Write throughout by maximizing interface bandwidth headroom. On paper speeds matter but actual usage involves mixed loads.

So if you covet responsiveness across everyday tasks, Seagate‘s SSHD tech delivers better application launch and load timings. Light gaming also benefits since random data access events trigger the cache frequently.

For large file copying or manipulations, WD‘s Black series SSDs provide unbeatable transfer rates. So know what your primary applications are!

Drive Recommendations – Who Should Buy Seagate or WD?

We‘ve covered a gamut of comparisons between these storage titans. Now as a closing guide, here are drive recommendations depending on your needs and budget!

Buy Seagate If You Need:
