Seagate Exos 20 TB BarraCuda 16 TB 7200 RPM CMR hard disk drives are limited-time deals

Currently, there are some great sales on SSDs, in particular, NVMe M.2 ones, like this SK hynix P41 Platinum P41. However, if you are in the market for a hard disk drive (HDD), then Seagate has you covered. That is because two high-capacity drives, the Exos X20 20TB and the BarraCuda 16 TB are currently at great prices (purchase links down below).

Since both of them are high capacity models, they are based on CMR or Conventional Magnetic Recording technology which is typically great for robust use cases like on NAS or (media) home servers and similar such scenarios. However, the Exos is enterprise-grade quality so it is definitely what you would want for 24x7 usage, but the BarraCuda can also serve pretty well but will be a better option for backup purposes.

The Exos X20 promises power-on hours of 8760 per year, while the BarraCuda claims 2400. The latter comes with double the DRAM cache, though with 512 MB of it, while the former has 256 MB, but it should still be plenty.

In terms of data transfer speed, Seagate promises up to 285 MB/s (272 MiB/s) from the Exos X20 and the BarraCuda is rated for up to 190 MB/s. These are the maximum sustained data transfer rates for the two drives. Since the Exos X20 is an enterprise-class product Seagate does disclose its random performance throughput, which is 168 IOPS for reads and 550 IOPS for writes, respectively.

While the BarraCuda's randoms are not specified it is expected to be lower and to compensate, it packs double the DRAM cache. Get the HDDs at the links below:
