Pros & Cons

Pros

  • ✓ 8TB in a 3.5-inch bay via 6-disk design, 33% more capacity per slot
  • ✓ Advanced Write Caching doubles random-write speed vs prior generation
  • ✓ SATA 6 Gbps interface drops into standard servers, NAS, and DAS chassis
  • ✓ Enterprise nearline build aimed at 24/7 bulk-data and unstructured workloads

Cons

  • ✗ Conventional PMR spinning disk, far slower than any SSD for random reads
  • ✗ Enterprise 3.5-inch drives run loud and warm in a desktop case
  • ✗ Ninth-gen recording tech, so this is an older generation, not current
  • ✗ No listed features on the ASIN: RPM, cache, and MTBF need manufacturer lookup
