This is what hard drives should be for your NAS, choose the right ones or they will break soon

If you have a NAS server or are thinking about buying one, you should know that there are hard drives specifically designed for this purpose, like for home NAS servers, as well as for more advanced equipment. Having good hard drives in your server is essential for good read and write performance and, above all, for reliability. There are models designed for NAS They are designed to store more data and last longer because these drives are designed to run continuously. Today we are going to explain the main differences between NAS hard drive and PC hard drive.

NAS hard drive is different from normal

The hard drives we can buy for desktop computer are different from the hard drives specially designed for NAS servers. There are certain important features in a hard drive that we should pay attention to before buying it:

  • capacity
  • Baud rate
  • Cash
  • Rotation speed (rpm)
  • Disc burning technology
  • MTBF Reliability

We will give a very illustrative example with two hard drives from the same manufacturer, but designed for different purposes: Seagate Barracuda Compute and Seagate IronWolf (regular, not Pro).

Seagate Barracuda computers:

  • capacity : up to a maximum of 5 TB.
  • Transfer rate : up to 140 MB/s.
  • Cache : 128MB
  • Speed ​​(rpm) : 5.400
  • Disc recording technology : CMP
  • MTBF reliability : not specified.

Seagate Iron Wolf:

  • capacity: Max up to 12TB.
  • Baud rate : up to 210 MB/s.
  • Cache : 256MB
  • Speed ​​(rpm) : 7.200
  • Disc Recording Technology : WRC
  • MTBF reliability : 1 million hours.

As you can see, the differences between a “regular” hard drive and a NAS-oriented hard drive are very different, especially if our equipment has several bays, since the latter will easily withstand the vibrations of other drives, while the former will shorten its life due to this . If we compare it with the Seagate IronWolf Pro, we see an even bigger difference:

Seagate Iron Wolf Pro:

  • capacity: up to 20 TB maximum.
  • Transfer rate : up to 285 MB/s.
  • Cache : 256MB
  • Speed ​​(rpm) : 7.200
  • Disc Recording Technology : WRC
  • MTBF reliability : 2.5 million hours.

As you can see, the “Pro” version is an improved version of IronWolf designed for use on servers with more than 8 bays, but it can also be used on servers with 4 or 6 bays without any problems. We will have better performance and greater reliability so that there are no data loss issues.

Recommended NAS hard drive models

Major hard drive brands such as Seagate, WD, or Toshiba have models specifically designed for computers, home and professional NAS servers, and more advanced data center servers. Depending on our use, we will have to use one or the other type of hard drive, since it is important that it is specially designed for this purpose.

In Seagate’s case, we have IronWolf and IronWolf Pro. The former are for home NAS or SMBs that have hardware with a maximum of 8 hard drive bays. These hard drives are rated for workloads up to 180 TB per year and have a MTBF of 1 million hours.

In the case of the IronWolf Pro, they are designed for servers of medium to large companies with equipment with more than 8 hard drive bays, they are designed for workloads up to 550 TB / year and MTBF up to 2 million hours.

As for WD brand, we have Red Plus line and Red Pro line, which are equivalent to IronWolf and IronWolf Pro. The main difference between the two is the maximum recommended number of bays.

The Toshiba brand also has hard drives designed specifically for NAS, this is the N300 line.

Finally, brands like Seagate and WD have hard drives for businesses, specifically EXOS and Gold, respectively. However, these hard drives do not have NAS diagnostic tools like older models from these brands.

As you can see, it is very important to choose the right hard drive that we use in our equipment in order to have the highest possible reliability.

1. Seagate IronWolf 4TB NAS Internal Hard Drive

Network Storage Heap

Interface: SATA 6Gb/s | Capacity: 6 – 12 TB | cache: 256 MB | RPM: +7200+

Ready for RAIDFaster than less features

Prices at the premium end of the sale, Seagate’s iron wolf’s own NAS optimization justifies the cost. The ability to run at high speeds of 7,200 rpm throughout the day without the risk of failure makes this one of the best options for peace of mind. It operates silently with virtually no vibration noise while still delivering excellent file sharing performance and overall speed. .

2. Western Digital Red 4TB NAS Hard Drive

Simple Hard Drive Designed for Maximum Storage Space

Interface: SATA 6Gb/s | Capacity: 1TB – 12TB | cache: 64B | RPM: 5400

Large Capacity Hard Drive: Better than competing 4TB models.

Just a few years ago, Western Digital’s 4TB NAS was the leader in packaging, offering more storage space than you could get from competing models. For now, that’s not the case anymore, it’s still a block with ample storage space. Designed for both businesses and consumers, it delivers high performance, especially in multi-drive environments where it delivers high sequential large block read and write speeds.

3. The WD Gold Gold 4 TB Corporate Class

The best transaction with a 12 TB

-term interface: SATA 6 Gbit / s | Capacity: 4TB – 12TB | cache: 128 MB | RPM: +7200

Excellent performance Affordable price Support is not as reliable as the competition’

If your business has a need to store large files (or lots of them), WD’s Gold Series stretches up to a whopping 12TB. And they have some interesting features: not least they are filled with helium to protect the tiny components inside that can be damaged by atmospheric turbulence. It’s on par with any of Seagate’s 12TB offerings when it comes to read and write performance, and offers a host of competing drives’ features at no extra cost.

4. WD Red Pro WD6003FFBX 6TB

Comes with useful features

Interface: SATA 6Gb/s | Capacity: 2TB – 12TB | cache: 256 MB | RPM: +7200

Excellent performance Reliable 10TB drive is quite loud

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

5. HGST Deskstar NAS 3.5″ 4TB

Great price that almost keeps up with the best

Interface: 6Gbps with SATA | Capacity: 4TB | cache: 64 MB | RPM: 7200 rpm

Good performance for occasional workloads. Magnificent value. Sequential workloads aren’t that high


HGST decided to stand out from the crowd by making this hard drive 7200RPM rather than 5400RPM like most 4TB competitors. While it doesn’t have the highest performance when it comes to sequential workloads, it handles random workload profiles in much the same way as more expensive enterprise drives, making it something of a bargain. It also contains useful features such as a vibration sensor which makes the drive suitable for rack mounting..

6. Seagate Exos 12TB Enterprise HDD Internal Hard Drive

Reasonably Priced Capable Enterprise Drive

Interface: 6Gb/s SATA | Capacity: 12TB | cache: 128 MB | RPM: +7200

TurboBoostHelium technology protects components. Can get noisy


Seagate Exos 12TB, designed to handle tough conditions throughout the day with high performance, is aimed at businesses. IT functions feature advanced write caching coupled with TurboBoost to improve performance and minimize the risk of data loss due to unexpected power loss. Seagate provides the drive with a five-year warranty.

7. Toshiba N300 8TB NAS

Drive optimized for reliability

Interface: SATA 6Gb/s | Capacity: 8TB | cache: 128 MB | RPM: +7200

Fast 7200 RPM operation 128 MB cache Noisy operation

Toshiba’s S300 offers its N300 model with a 180 TB/year workload for small offices that need the high reliability of a NAS hard drive. It offers strong performance at 7200rpm with a large 128GB cache, and it’s powered by built-in RV sensors inside that dampen the impact of rotational vibrations on the components.
