Seagate’s IronWolf Pro is the cheapest internal hard drive you can buy per capacity for Cyber Monday shipped by the retailers themselves*. At the time of writing, the offer ends in 20 hours.
At $16.50, the Seagate IronWolf Pro ST20000NT001 20TB ($329.99 at Newegg) is the ideal choice for NAS or for a backup project (JBOD or RAID), saving you a staggering $170.01 or 34%. It is its cheapest price since launch.

This 3.5-inch drive has 256MB cache and a 7200RPM rotational speed. That makes it perfect for local backup storage if cloud storage is simply too slow. It is geared towards the enterprise market and uses CMR technology (rather than the more controversial SMR one) as well as helium to deliver a cracking HDD.
Seagate says that it is designed for 24×7 usage and offers a 550TB/year workload rating with a five year warranty and a complimentary 3-year rescue data recovery service. I’d have preferred to have an additional two years to match the warranty.
The IronWolf Pro is optimized for NAS setup through its firmware and software setup; our review highlighted one key feature: the inclusion of RV sensors that help improve performance by adjusting thermal variables on the fly, helping it hit 287/279MBps in sustained read/write, almost on par with first generation SSDs.
* Note that I’ve only chosen from hard drives that are sold/shipped by Amazon or Newegg, rather than third parties. The latter group tends to offer cheaper prices but has strings attached (e.g. shipping from China or Hong Kong) and a higher rate of returns.
