More Space + Added Security

Whether you have your Fusion RAID storage system configured with a hot spare, perform incremental backups, or swap out large amounts of data, it's always handy to have extra drive modules around. Fusion drive modules employ Enterprise/RAID Edition hard drives or select, Sonnet-certified drives that have been selected for their superior performance, error handling, and reliability characteristics, especially when used in RAID groups. These drives are subjected to hours of additional, stringent testing to check for soft errors, vibration, and other reliability predictors. Just the sturdiest drives pass these tests and are prepared with special RAID-optimized firmware to become the building blocks of a super-reliable Fusion storage system.

Technical Notes

  1. Although hard drive manufacturers and Mac OS X 10.6 define 1 gigabyte as 1,000,000,000 bytes, many other computer operating systems calculate a gigabyte by dividing the bytes by 1,073,741,824 (). This distinction may be a cause of confusion, as a hard disk with a manufacturer rating of 1000GB may have its capacity reported by the operating system as 915GB.
