How We Decided

In order to bring you our selections for the best NAS hard drive, we looked for durability, workflow capacity and compatibility, as well as data security and redundancy. To that end, we only considered disk stations with at least 2 bays capable of supporting 8 TB or more of total storage and with AES encryption support.

We included “plug and play” or ready to go NAS boxes which come with an enclosure, a hardware interface to run the hard drives, and a CPU with firmware to run file transfer protocols. We also included internal hard drives designed to be used in these NAS boxes or multi-bay desktop server systems.

When it came to the hard drives themselves, we limited our search to drives that were compatible with RAID configuration and optimized for 24/7 use. We looked for power consumption figures, where available, and insisted on a claimed throughput rate of at least 100 TB/ year.

Finally, we only looked at NAS hard drives for Mac, Linux and Windows compatible systems that used commonly-accessible hardware interfaces like SATA. To ensure performance in our selections for the best NAS hard drive for media streaming, we looked for at least 64 MB cache size and 5400 RPM.

Best NAS Hard Drive Buyer’s Guide

Features to Consider

  1. Capacity
    Storage capacity can vary greatly among network hard drive systems. Depending on your needs, a 2TB HDD for NAS might be enough, but if you’re looking to integrate multiple media sources, or you’re looking for the best NAS drive for Plex servers, you’ll likely want to look into purchasing a 4TB product.
  2. Hardware Interface
    Make sure the drives you’re considering are easy to format and set up with your existing hardware. A common, industry standard hardware interface such as the SATA III is a good start. This connection allows for specs of up to 6 Gigabits per second bandwidth. For a NAS unit or home RAID desktop server unit, look for convenient and high bandwitdh physical connection options. If you plan to use the NAS with media devices relying on HDMI interfaces, make sure it comes with an HDMI port.
  3. Cache Size
    For desktop servers and single drive systems, a large, 128 or 256 GB cache may be necessary in order to ensure speed of retrieval and overall performance, whereas for use cases such as CCTV libraries, a smaller 64 GB cache is likely enough.
  4. Vibration and Heat Sensors
    Especially important when looking for a long-term storage solution or if you’re trying to find the best value NAS HDD in terms of operating costs, heat and vibration sensors add to durability and extend the lifetime of individual hard drives. HDD for NAS systems are designed to withstand the rigors of 24/7 usage and the heat and vibration of multiple drive bay server enclosures.
  5. Workflow capacity
    Most of the best hard drives advertise at least 180 TB/ Year workflow; this is important if you plan to use the NAS as a primary data storage or backup for home or office use.
  6. MTBF
    MTBF is a statistical term and stands for “mean time between failures.” Used in the context of external hard drive and drive failure, this provides an estimate of the claimed lifetime of a product. The best NAS drives will have an MTBF of around 1 million power-on hours.

There are many storage devices to choose from like the best external hard drive for Xbox one, the best external hard drive for PS4. There’s also the best external hard drive for Mac that you can buy. Which is why we research these devices to make sure they are top rated. We even put in the hours on the best micro SD card.
