Basic Information: Western Digital vs Seagate

If you know anything about storage devices, you must have heard of Western Digital and Seagate, two of the world's top storage manufacturers. Especially when it comes to buying computer hard drives, you should be torn between Western Digital and Seagate. In order to solve your problems and worries, this article will introduce you to the differences between Western Digital and Seagate in terms of internal and external hard drives respectively. But before that, you should know the basic information of Western Digital and Seagate.

Western Digital VS Seagate

About Western Digital

Weatern Digital Hard Drives

Born in 1970, Western Digital is a world-renowned manufacturer of computer hard drives and data storage provider. The original main product is the hard disk drives (HDD). But after acquiring SanDisk to become the parent company, it has also begun to make efforts in integrated circuits and solid-state drives (SSD). Currently its hard drives can be divided into two main categories: consumer and enterprise.

The consumer grade can also be divided into Green (entry-level SSDs), Blue (mainstream drives), Black (performance drives), Red (NAS-specific drives), and Purple (surveillance video-specific drives). The enterprise class can also be divided into Xe (high-density performance storage), Re (high-capacity storage), Re+ (a combination of power-optimized and high-capacity storage), Se (for NAS and lateral expansion architectures), and Ae (energy-efficient HDD cold data set storage solutions).

About Seagate

Seagate Technology was born in 1979 and is a world-renowned computer hard drive and data storage company. Its main products include desktop hard drives, enterprise hard drives, laptop hard drives and micro hard drives, and it offers a dedicated hard drive testing tool SeaTools and a hard drive backup tool Seagate Discwizard.

Although Seagate's main product is HDD, it still invested $100 million in research and development of SSD in 2008. At present, SSDs that mix SLC and MLC chips have been successfully developed. The former has better performance, while the latter has a lower cost per chip.

Seagate Hard Drive

Taken together, Seagate's current products can be divided into the following types:

  • Barracuda: 3.5-inch desktop-class HDD up to 7,200 rpm.
  • Skyhawk: a dedicated hard drive for surveillance video.
  • Ironwolf: NAS-specific hard drive.
  • EXOS X and EXOS E: dedicated enterprise drives.
  • Firecuda: SSD products.
  • Nytro: SSD products.

After understanding the above, I will introduce the differences between Western Digital and Seagate in terms of internal hard drives and external hard drives.

Western Digital vs Seagate: Internal Hard Drives

Western Digital and Seagate are both good options if you want to buy a hard drive installed inside your computer. But in fact, there are some differences in their hard disk products, and they have their own advantages and disadvantages. So, how can you choose the better one? First, let's start by understanding the differences between these two labels when it comes to HDDs.

Western Digital vs Seagate: HDD

As you know, HDDs are the main products of Western Digital and Seagate. If you want to choose a more suitable HDD, which one is better between them? You can evaluate all three aspects: performance, storage capacity and reliability.

🚩 Performance

The most intuitive indicator for judging the strength of hard disk performance is the read and write speed. Faster read and write speeds will also make your computer run faster. Although there are some differences in read and write speeds between HDD models.

But on the whole, Seagate's HDD read and write speed is faster than Western Digital, and the current maximum speed can reach 7200 RPM. It is worth mentioning that HDDs are divided into vertical disks and untitled disks, of which the former has stronger performance than the latter. Therefore, when purchasing HDDs, be careful not to buy HDD products with untitled disks.

🚩 Storage Capacity

Storage capacity is an important indicator when shopping for HDDs and is also the biggest advantage HDDs have over SSDs. Among them, Western Digital was the first company in the world to launch a 2TB SATA HDD. The company also launched the world's first 14TB HDD in October 2017 with the HGST Ultrastar Hs14.

Seagate's update pace has been a bit slower, but it's also currently launching the BarraCuda Pro with a 14TB capacity. Therefore, both Western Digital and Seagate can meet the hard disk capacity requirements of all users, and you can choose the appropriate storage capacity according to the actual situation. It's also worth noting that Western Digital's HDDs are more expensive than Seagate's for the same capacity.

🚩 Reliability

Any hard drive will accumulate certain errors after long-term use, which will eventually lead to failure. So when shopping for a hard drive, you need to focus on the reliability of the drive in addition to the storage capacity and performance. The more reliable your drive is, the longer it will last.

Despite the different models and capacities, according to a study by BackBlaze, among all HDD manufacturers such as Western Digital, Seagate, and Toshiba, Western Digital has the highest failure rate. The feedback results of users on the network can also prove this point. Therefore, in the Western Digital VS Seagate reliability comparison, the latter is significantly better.

Which Is the Better Internal HDD?

On the whole, the advantages of Western Digital's internal HDD are strong performance, large storage capacity and a variety of options. The disadvantage is that it is less reliable and expensive. The advantages of Seagate's internal HDD are high performance, large storage capacity and a variety of options, strong reliability and low price. The disadvantage is that the Flash acceleration effect cannot appear in time.

In summary, it is recommended that you purchase Seagate's internal HDDs. The following is a visual comparison between Western Digital and Seagate in terms of performance, storage capacity, reliability, and price.

Western Digital vs Seagate: SSD

Western Digital and Seagate were both firm HDD advocates, but under the impact of the SSD wave, they also began to study SSDs. In the latest M.2 interface (NVMe PCIe 4.0 protocol), Western Digital SN850 achieves 7000MS/s sequential read, 5300MS/s sequential write, and 1000K (IOPS) random read. The Seagate Coldplay 530 sequential read reaches 7300MS/s, sequential write reaches 6000MS/s, and random read reaches 1000K (IOPS).

By comparison, Seagate's SSDs lead the pack in terms of performance. In terms of storage capacity, reliability and price, the gap between the two is small. Overall, Seagate SSD is the best choice.

Seagate vs Western Digital: External Hard Drives

External hard drives can be easily connected to a computer via a USB cable and operate in a plug-and-play fashion. External hard drives have larger storage capacities and are usually used for data backup or as network drives. Among them, Western Digital and Seagate are common manufacturers.

If you are also entangled in Western Digital and Seagate when purchasing an external hard drive, please read the following content in detail to choose a more suitable external hard drive. It should be noted that the external hard drives of Western Digital and Seagate are mainly HDDs, and SDD-related products are few and small in capacity, so they are not included in the reference range. Next, we need to understand the following three common types of external hard drives.

Removable Hard Drives

Both Western Digital and Seagate offer removable external hard drives of varying capacities. Among them, the most popular of Western Digital is the My Passport series, and the most popular of Seagate is the Backup Plus series. These series will provide different capacity versions (up to 5TB), you can choose according to your needs.

My Passport SSD

Desktop Hard Drives

If you need to store a lot of games, photos and videos, a removable hard drive with a maximum capacity of 5TB may not be sufficient. At this point you are recommended to choose a desktop drive. Among them, Western Digital's My Book Duo desktop hard drive can reach a capacity of 28TB after RAID 0 or RAID 1 configuration. Even the standalone My Book desktop hard drive can provide up to 18TB of capacity.

The Seagate Coldplay series can provide a maximum capacity of 16TB, which is enough to meet the storage space needs of most users. But on the whole, Western Digital is better.

NAS Device

The best choice for NAS devices is Western Digital. This is because Western Digital can offer up to 40 TB in the My Cloud Pro and Expert series. While Seagate doesn't currently have first-party NAS servers, their product is the 14TB IronWolf series, which are drives designed for NAS.

Which Is the Better External Hard Drive

The advantages of Western Digital external hard drives are strong performance, plug-and-play technology, and the size of the mainstream 2.5-inch. The disadvantage is that the size is small and it is easy to receive shock, it is easy to overheat after long-term use, and some products are made of plastic material, which leads to weak shock resistance.

The advantages of the Seagate external hard drive are that the removable hard drive is simple to set up, small in size and light in weight, perfectly adapted to the Windows operating system and can be automatically recognized. The downsides are the short warranty period and the fact that the external hard drive doesn't come with backup software.

To sum up, it is recommended that you buy an external hard drive from Western Digital. Here's a visual comparison of performance, storage capacity, battery life, and data security between Western Digital and Seagate:
