Price – Toshiba N300 vs Seagate IronWolf comparison

The Toshiba N300 series comes in three high capacities: 4TB (the one we’ve reviewed here), 6TB and 8TB. The 4TB version costs £120 (around $160, AU$200), while the 6TB version will set you back £200 (around $260, AU$350), and the 8TB version costs £250 (around $320, AU$440).

If 10TB still feels like too much space, you can also get the IronWolf hard drives in 1TB, 2TB, 3TB, 4TB, 6TB and 8TB capacities as well. The 10TB version will set you back £314 ($264, AU$469). And, if 10TB isn’t enough, Seagate is now also offering a 12TB drive.

Who is this for – Toshiba N300 vs Seagate IronWolf

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.

What is the key difference – Toshiba N300 vs Seagate IronWolf?


Toshiba N300 has a standard 3.5-inch design which means it can easily be installed in PCs, servers and NAS devices, but not laptops. The high capacities are welcome, and its fast RPM means it delivers very good data transfer speeds.

The IronWolf is an excellent hard drive that offers fast and dependable storage. The fact that its helium design means you can get huge amounts of capacity into a regular 3.5-inch hard drive is incredibly impressive, and means even if you use a number of these drives in a RAID array, you’ve still got plenty of storage space to play with.

Rotational speed

Despite throttling the speeds when temperatures get too hot, Toshiba is still bullish about the transfer rates the N300 can achieve, claiming speeds of 200MB/s. This is achieved thanks to a 128MB buffer, and a rotational speed of 7,200 RPM, which is faster than the speeds of many NAS-orientated hard drives, such as the WD Red, which spins at only 5,400 RPM.

The Seagate IronWolf has sequential read speeds of 250.2 MB/s and write speeds of 229.2 MB/s, which are very impressive, considering this is a 7200RPM hard drive, and handily beats the Seagate Enterprise Capacity 3.5 HDD V.4 6TB Hard Disk, which reached 213MB/s read and 212MB/s write speeds in the same test.

Read & write speed

With the Toshiba N300 4TB hard drive reaching sequential read speeds of 210MB/s, and write speeds of 209.2MB/s in the CrystalDiskMark benchmark test.

Meanwhile the IronWolf 10TB, another NAS-orientated hard drive, scored 250.2MB/s read and 229.2MB/s write, offering both faster speeds and larger capacities.

In comparison, the WD Rd 8TB scored read speeds of 185MB/s and write speeds of 185.4MB/s. That’s quite a difference, and mainly down to the faster spin speeds of the Toshiba N300.

WD Red Pro WD6003FFBX 6TB

  • Interface: SATA 6Gbps
  • Capacity: 2TB – 12TB
  • Cache: 256MBRPM: 7200

+Great performance



-10TB drive is quite loud

WD’s Red Pro continues the company’s mantra of offering affordable and reliable storage that reduces total cost of ownership. It packs 3D Active Balance Plugs tech, which is said to significantly improve the over drive performance and reliability. That’s in addition to NASware tech, which is designed to improve reliability and system performance, reduce downtime and simplify the integration process while offering robust data protection.

  • Interface: SATA 6Gbps
  • Capacity: 4TB – 12TB
  • Cache: 128MBRPM: 7200


+Excellent performance

+Smartly priced


-Support is not as robust as rivals’

If your business has a requirement to storage large files (or just lots of them), WD’s Gold series stretches all the way to a massive 12TB in size. And they boast some interesting traits: not least being filled with helium to protect tiny components inside that can be come damaged by atmospheric turbulence. Its on par with any of Seagate’s 12TB offerings when it comes to read and write performance and offers many of its rival drives’ features at no extra cost.

Western Digital Red NAS Hard Disk Drive


  • Interface: SATA 6Gbps
  • Capacity: 1TB – 12TB
  • Cache: 64BRPM: 5400

+Large capacity hard drive

+Performs better than rival 4TB models


-Average multi-drive small block sequential transfer speeds

It was only a few years ago that Western Digital’s 6TB NAS was the pack leader, offering more storage space than you could get from competing models. While that’s no longer the case, it’s still a unit with capacious storage space. Designed for both business and consumers, it offers fast performance especially in multi-drive environments where it boasts strong large-block sequential read and write speeds.
