EXOS X20
Seagate manufactures hard drives that specifically address the needs of the hyperscale storage market. As the flagship of the Seagate® X class, the Exos™ X20 enterprise hard drives are the highest-capacity hard drives in the fleet.

Best-Fit Applications
  • Hyperscale applications/cloud data centers
  • Massive scale-out data centers
  • Big data applications
  • High-capacity density RAID storage
  • Mainstream enterprise external storage arrays
  • Distributed file systems, including Hadoop and Ceph Enterprise backup and restore— D2D, virtual tape
  • Centralized surveillance
• All 4Kn/512e drives ship in 512-byte emulation mode but can be
easily reformatted to 4Kn (and vice versa) with the FastFormat
feature.
• FastFormat only works with 512e and 4Kn. You can’t use FastFormat with 512-byte native drives.
• FastFormat reformats the drive, so all data on the drive will be lost once you issue the command. Don’t forget to back up your data before issuing FastFormat!
• T10 fast format conversion between 4K and 512E configurations is possible only if sector sizes are exact multiples of 8.
• The new sector size will take effect only after a fast format.

Compatibility: Compatible with systems that support 20TB 3.5" SATA HDDS
