The best NAS hard drive delivers more secure and efficient processes when managing and sharing high-volume data between multiple users.
My team and I have spent years testing, reviewing, and rating storage solutions from SSDs to the best NAS devices. Now, we're rounding up the best NAS drives - with an emphasis on speed, capacity, and value for money.
For that reason, the Seagate Ironwolf Pro is my top pick overall, with a hard drive that offers good speeds, plenty of storage capacity, and a price-point that makes it more accessible than most on the market right now. You can check out the review below, alongside alternative picks for your budget and use-case.

The best NAS hard drive: quick list
The best NAS drive overall
This high-capacity HDD is perfect for NAS servers thanks to its accessible price and endurance for the long haul, though it has a lower yearly workload limit than some enterprise options.
The best budget NAS hard drive
While the performance on this drive might not match the best NAS drives out there, this drive is all about maximizing storage capacity at a low price, and here it succeeds brilliantly.
The best NAS hard drive for enterprise
Enterprise clients need more than most hard drive users, including high capacities and speeds, and the Seagate EXOS had drive is as fast as a hard drive can get while offering up to 20TB.
The best NAS hard drive overall
Amazingly, cramming ten 2TB platters and 20 heads into a 3.5-inch drive package is possible. But Seagate achieved this using CMR technology and replacing the atmosphere inside the drive with Helium.
On the plus side of this equation, the new IronWolf Pro 20TB is 2TB bigger than the 18TB model, about 25MB/s faster at reading and writing, and it's more power-efficient. All these advantages come at a price that is only marginally more than the 18TB option. So it's a no-brainer for commercial and enterprise NAS to support the needs of creative professionals and large businesses, indeed?
The blot on this landscape is the yearly workload limit of 300TB, which could quickly be eaten by regular integrity testing, not to mention actual use. With data center drives offering 550TB workload limits at a very similar price and nearly identical performance, the IronWolf Pro might not be the best drive for the job, depending on your NAS profile.

The best budget NAS hard drive
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 businesses and consumers, it offers fast performance, especially in multi-drive environments with strong large-block sequential read and write speeds.

The best NAS hard drive for enterprise
Another Seagate drive with ten 2TB platters in the classic 3.5-inch form factor to sit alongside the new IronWolf Pro 20TB. The only significant difference on the outside is that the EXOS comes in a SAS flavor in addition to a conventional SATA variety model.
The EXOS drive beats the IronWolf Pro with a workload limit of 550TB, a significant improvement over the 300TB of its brother mechanism. These are the same workload limits as the Western Digital UltraStar DC HC560 20TB and WD Gold 20TB.
Tuned for data center use, the EXOS 20TB is designed for high-capacity servers, enterprise NAS systems, and bulk storage. While the cost is higher than the 18TB models, it is slightly faster and offers enhanced rack space efficiency. Until the rumored microwave-assisted switching (MAS-MAMR) drives come along, the EXOS 20TB is as big a hard drive as you can buy.

How to choose the best NAS hard drive for you
When selecting a NAS hard drive, it is important to consider the capacity, speed, and connectivity options that best meet your needs. Larger capacity hard drives can store more data, while faster hard drives can improve data transfer speeds. It is also important to consider the connectivity options, such as whether the hard drive supports Ethernet or WiFi, as well as the type of data interface (e.g. USB, SATA).

While NAS hard drives can be used as a primary storage device, they are typically used as an additional storage option or for file sharing. They may not be suitable for use as a primary storage device for larger files or for high-performance applications, as they may not have the same level of speed and performance as a local hard drive.
