EXOS X18
Seagate manufactures hard drives that specifically address the needs of the hyperscale storage market. As the flagship of the Seagate® X class, the Exos™ X18 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.
