Seagate IronWolf Pro 20TB 7200 RPM CMR NAS hard disk is a great deal after a long time

The Seagate 20TB 7200 RPM IronWolf Pro CMR-based NAS hard disk will cost you only $24 per TB with this deal.

If you are in the market looking for high-capacity hard disk drives (HDDs) to set up a NAS (network-attached storage) for your home server or music or movie library and are looking for the best options available, Seagate has its IronWolf Pro 20TB 7200 RPM CMR HDD at a very good price of $480, which means you are paying only $24 per TB, making it a pretty good deal in these hard times (purchase link under the specs table down below).

As mentioned above, these are based on CMR, or Conventional Magnetic Recording, technology. These are better for NAS compared to SMR (Shingled MR) because they are more robust. CMR drives can deliver consistent write speeds, reliable RAID rebuilds, and durability for 24x7 workloads. Unlike SMR, CMR avoids overlapping tracks, thus ensuring predictable performance and long-term reliability, which are key for continuous NAS and similar operations.
