RAID 0 “Drive Striping” Mode

• The two drives show up as a single large disk with a size equal to the combined capacities of both drives. RAID 0 is used when speed is the primary objective; it does not provide data redundancy for protection. The reading and writing of data files are spread across both drives to gain speed by distributing the workload. This allows for the fastest data transfer rates, but if one drive fails the whole array becomes corrupted. The data will be lost.
• Identical SATA drives (model, capacity, firmware) are required.
• Not supported with NVMe U.2 drives.

RAID 1 “Drive Mirroring” Mode

• The two drives show up as a single disk with a size equal to the capacity of a single drive from the array. RAID 1 copies (or “mirrors”) the data from the first drive to the second drive. This is useful when reliability and redundancy are more important than capacity or maximum speed. When one drive fails, it can be replaced, and the data can be rebuilt automatically from the other functioning drive. See Section 2.5 “Replacing Drives” for more details on the drive replacement and rebuild process.
• Identical SATA drives (model, capacity, firmware) are required.
• Not supported with NVMe U.2 drives.

Span Mode

• Both drives show up as a single large disk, but one which functions differently than RAID 0. The total size will depend on the drives installed; unlike RAID 0 or RAID 1 you can use drives of different capacities. A span is an array (but not a RAID) in which the data is written sequentially across the drives. When one drive becomes full, subsequent data is written to the second drive. This combines the capacities of the drives, but it does not provide any performance or data redundancy benefits.
• Not supported with NVMe U.2 drives.

Independent Drive Mode

• Each drive will appear individually without being combined. If you are using U.2 SSDs, drives of differing capacity and model, or if you are using only one drive, this is the mode to use. The Red LED indication for missing or failed drives is disabled for U.2 drives and drives used in Independent Mode.

• Download OWC SoftRAID for Mac.
• Please review and follow the steps outlined in OWC SoftRAID Installation for Mac.
• Please review and follow the instructions outlined in Creating a macOS OWC SoftRAID Volume.

• Download OWC SoftRAID for Windows
• Please review and follow the steps outlined in OWC SoftRAID Installation for Windows.
• Please review and follow the instructions outlined in Creating a Windows OWC SoftRAID Volume.

1. Open the “Disk Utility” application on your Mac.
2. Choose “File” and select “RAID Assistant”.
3. Select a set type:
   • Striped (RAID 0) set: A striped RAID set can speed up access to your data. You can’t create a RAID set on your startup disk; you must first start up your computer from another disk.
   • Mirrored (RAID 1) set: Protect your data against hardware failure with a mirrored RAID set. When you create a mirrored RAID set, your data is written to multiple disks so the information is stored redundantly. You can’t create a RAID set on your startup disk; you must first start up your computer from another disk.
   • Concatenated (JBOD) set: Increase storage space with a concatenated disk set. If you need one large disk, but you have several smaller disks, you can create a concatenated disk set to use as one large disk.
4. Select the checkboxes of the disks you want to include in the set.
5. For each disk, click the pop-up menu in the Role column and choose “RAID slice” or “Spare” to designate the disk as a standard member or spare in the set, then click Next.
6. Enter a name for the RAID set in the RAID Name field.
7. Click the Format pop-up menu, then choose a volume format that you want for all the disks in the set. (See File system formats available in Disk Utility.)
8. Click the “Chunk size” pop-up menu, then choose a disk chunk size that you want used for all the disks.
   
   NOTE: When you create a striped set, chunks of data from the same file are distributed across the drives. Ideally, you want data distributed across drives evenly and at an optimum size so that it can be efficiently accessed. If you want high data throughput from your set, choose a smaller chunk size so that data is spread across the drives and one drive can be accessing data while another is seeking the next chunk. With mirrored disk sets, choose a chunk size that matches the data you’re accessing. For example, when working with video files, your Mac is accessing large chunks of data, whereas when using a database of many small records, your disks may be accessing smaller chunks of information.
   
9. If you are creating a mirrored RAID set, select the “Automatically rebuild” checkbox to allow the set to be automatically rebuilt when member disks are reconnected
10. Click "Create" and then click "Done".

• If one of the SATA drives in a Hardware RAID 1, 0, or Span fails (or is missing or not connected properly), the corresponding drive LED on the front of the device will light up a solid red.
• If the OWC Thunderbolt 5 ThunderBay Dual is set up as a RAID 1, a drive that has failed can be replaced to rebuild the array. The data will remain accessible via the functioning drive until the array is rebuilt with a new drive.
• If the OWC Thunderbolt 5 ThunderBay Dual was configured as a Hardware RAID 0:
  • The data is lost if a drive failed.
  • The data can be recovered if the enclosure has failed. NOTE: The replacement enclosure must be the exact same OWC Thunderbolt 5 ThunderBay Dual model and matching RAID mode must be set before moving drives. Older OWC Thunderbolt 5 ThunderBay Dual models had a black ethernet port on the back, while newer OWC Thunderbolt 5 ThunderBay Dual models have a yellow ethernet port. Please contact support for assistance and warranty details.
• When in Span, only the data stored on the failed drive is lost, although data recovery software will be required to retrieve the data from the other drive.
• If the drives were configured into Independent mode, then the data on the drive that did not fail will remain intact.

• NOTE: Opening the OWC Thunderbolt 5 ThunderBay Dual if pre-built (drives installed from factory) will VOID the warranty. If you wish to remove or replace the drives after the expiration of the original warranty, you may do so at that time.
  
  • A failed drive must be replaced with an identical drive (model, capacity, firmware)
  • The OWC Thunderbolt 5 ThunderBay Dual needs an active data signal to remain powered on. If it is disconnected from the computer, or if the computer goes to sleep or turns off, the device will power off. To minimize the rebuild time, it is recommended to keep the device connected to the computer (with the computer powered on), and disable any drive sleep settings on the computer for the duration of the rebuild. While rebuilding, the Drive LED indicator of the original drive has a slow pulsing green light, and the Drive LED indicator of the new drive will light up a solid red. The Drive LED indicator statuses will return to normal once the rebuild process is complete.

• If the Thunderbolt 5 ThunderBay Dual is set up as a RAID 1, a drive that has failed can be replaced to rebuild the array. The data will remain accessible via the functioning drive until the array is rebuilt with a new drive.
• Drive failures configured as a RAID 0, Independent, or Span don’t have a rebuild option and the data is lost. If the enclosure was purchased with drives and it is still under warranty, contact OWC technical support for assistance (see Section 4.4 “Contacting Support”).
• Enclosure failures configured as a RAID 0, Independent, or Span can have the data recovered. Move the drives to another matching OWC Thunderbolt 5 ThunderBay Dual model preset to the drive RAID configuration.
  • NOTE: Older OWC Thunderbolt 5 ThunderBay Dual models have a black ethernet port on the back | Newer OWC Thunderbolt 5 ThunderBay Dual models have a yellow ethernet port.

As of Windows 10 v. 1809 the default Disk Removal Policy is ‘Quick removal’ instead of ‘Better performance’.

NOTE: OWC storage solutions that are experiencing slow read/write speeds should consider checking and changing the Windows disk removal policy. Changing from "Quick removal" to "Better performance" can increase disk performance. OWC offers the application OWC Disk Performance to help change the Disk Removal Policy. Changing from "Quick removal" to "Better performance" can also be changed through OWC SoftRAID or manually through the operating system.

Please review the support article Storage Solutions: OWC Disk Performance for additional details.
