The disks are ready to be formatted and used as four separate disks or used in a RAID set.
Promise Technologies Pegasus J4User Manual Create a striped RAID set Disk Utility A striped RAID set (also called “RAID 0”) is used when high performance is required for the application used to access the data on the disks. For example, if the data contained on the J4 will be used primarily for video editing, a striped RAID is preferable because non-linear media editing requires access to data at a speed that cannot normally be achieved with a mirrored RAID set.
Promise Technologies Pegasus J4User Manual Create a mirrored RAID set Protect your data against hardware failure with a mirrored RAID set (also called “RAID 1”). It writes your data to two or more disks so that each disk in the set contains the same data as every other disk. You can’t create RAID set that contains partitions on your startup disk. To create a RAID disk that contains partitions on that disk, you must first start up your computer from another disk or the Mac OS X installation disc. 1.

Select one of the disks that you want in the set, and then click RAID. 3. Click Add (+), and type a name for the RAID set. 4. Choose a format from the Format pop-up menu, and then choose Striped RAID Set from the RAID Type pop-up menu. 5. Drag two disks to the list on the right. 6.
Promise Technologies Pegasus J4User Manual What is RAID? RAID 0 or Striped RAID using all four disks on the J4 The Mac disk utility is used to create a file system for the physical drives in the J4. The section “Configure the Hard Disks” on page 15 provides a description of the procedures to create different RAID configurations.
