Be alert when looking at HDDs, as not every drive is born equal and worthy of your money or a place of honor in your PC. Differences in recording technologies, like whether the drive uses conventional magnetic recording (CMR) or shingled magnetic recording (SMR), come with or without DRAM, and the spindle speeds they offer can all have a tremendous impact on the performance and pricing of your drive. We're compiling the best HDD deals in this constantly-updated article, based on our in-depth knowledge gained from thorough reviews, extensive benchmarks, and comprehensive historical price analysis.

We list internal drives for PCs, the best HDDs for NAS systems, and external hard drives, with the latter possibly including shuckable drives, meaning you can pry the HDD out of the external casing and use it in your desktop PC. Proceed at your own risk with Shucking, though: Shucking the drive voids the warranty, but you do get a capable drive for far cheaper than you normally would (be sure to do your homework first to determine if the drive can be shucked; not all models can).

HDD Deals: What to Look For

  • It is important to be aware of the drive’s form factor, with 3.5-inch being the most common for the best HDDs (this is the only type we cover). If you need a 2.5-inch, your options are more limited, especially for capacity. Otherwise, your computer case’s ability to house a certain number of 3.5-inch drives might be your primary limitation.
  • The ubiquitous SATA interface is used for desktop PCs, and most motherboards have ample available ports, which makes expansion easy. Most consumer NAS systems also use SATA, with the SAS interface typically reserved for servers and enterprise-class NAS.
  • If you're shopping for an HDD, you’re probably looking for the lowest possible cost per terabyte, but you should also consider performance and support for specific applications. There are several potential performance pitfalls to consider when purchasing a new HDD, and the type of recording technology is one of the most crucial factors. Unless you are solely interested in cost and willing to sacrifice performance, we only recommend conventional magnetic recording (CMR) drives and not shingled (SMR), as the latter comes with performance and operational caveats.
  • For performance, HDDs are also often gauged by rotations per minute (RPM), which is usually a direct indicator of performance. The RPM value affects both sequential transfers and random access latency. Lower RPM drives tend to be quieter and more efficient, while higher RPM drives have better performance. There are also variable RPM drives that try to achieve the best of both worlds. Power draw, heat, and noise are factors related to performance.
  • HDDs also have a certain amount of DRAM to help temporarily cache data. This amount of cache typically scales with the drive's capacity. More cache is, of course, better, but if it comes at the expense of something else — for example, a support service — then you should carefully consider your priorities when making a purchase.
  • You will want specialized drives for NAS, surveillance/DVR/NVR, raw storage for media and backups, or for heavier workloads. Certain drives will offer a better value for the money if you just want the extra capacity, or you may require a lower RPM drive to avoid the noise associated with faster drives.
