    Mac OWC SoftRAID Setup

    Windows OWC SoftRAID Setup

    • If you are using the OWC ThunderBay 4 mini with the Windows operating system, the pre-installed drives need to be reconfigured before they can be used. The following options will allow the Mac formatted OWC ThunderBay 4 mini to work as a Windows formatted device.

    2.2 Assembly Steps

    This section describes the process of installing drives into the OWC ThunderBay 4 mini if purchased as a bare enclosure.

    1. Insert one of the keys into the lock on the top left of the security faceplate.

    2. Turn the key clockwise, then pull it towards you. The faceplate will swing open.

    3. Pull up on the faceplate to remove it.

    4. Pull on the tab at the center of an empty drive tray to remove the tray from the enclosure.

    5. Set the drive tray as shown on your work surface. If you are replacing an existing hard drive, unscrew it from the drive tray at this time.

    6. Place the hard drive inside the drive tray as shown. The label should face up and the SATA connectors should be on the far rear corner of the drive.

    7. Fasten the drive into the drive tray using four of the included screws (two per side)

    8. Slide the drive tray back into the rails in the ThunderBay 4 mini and push until it is seated fully, then push in on the thumbscrew and turn it clockwise until it stops turning. If you encounter resistance, do not force the drive tray. Remove it, check to make sure there are no obstructions and that the drive tray is lined up correctly, then slide it in again.

    9. The installed drives are ready to be formatted. Move onto section 2.3 “RAID Configuration Options” for instructions on how to format and configure the OWC ThunderBay 4 mini.

    2.3 RAID Configuration Options

    OWC SoftRAID RAID Configuration

    • Downloading and installing the latest version of OWC SoftRAID is recommended to experience the best performance from the OWC ThunderBay 4 mini.
      • NOTE: OWC ThunderBay 4 mini devices come bundled with "3 Years of SoftRAID Premium Access". Please visit OWC SoftRAID Product Details for more information regarding SoftRAID and the bundled Premium Access.
    • SoftRAID will assist with formatting the installed drives and setting up a RAID volume.
      • NOTE: The OWC SoftRAID license is located on the bottom of the OWC ThunderBay 4 mini.

    Mac OWC SoftRAID Setup

    Windows OWC SoftRAID Setup

    Mac RAID Configurator

    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.
      1. 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".

    Device Management

    3.1 Drive Failure

    • If the OWC ThunderBay 4 mini was configured as a RAID 0, the data on the array is lost and the disk is no longer usable.
    • If the OWC ThunderBay 4 mini was configured as a RAID 5, the RAID card will alert the user with a beeping tone. The RAID can continue to be used, but the drive should be replaced immediately.

    3.2 Replacing Drives

    • The Hot-Swap function can be used to rebuild disk drives in arrays with data redundancy such as RAID level 1, 3, 5, 6, 10, 30, 50 and 60. The data will remain accessible via the functioning drive until the array is rebuilt with a new drive.
      • 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”). If the unit is outside its warranty or was purchased without drives, follow the assembly instructions to access and replace the failed drive.
        • NOTE: A failed drive must be replaced with an identical drive (model, capacity, firmware). Refer above to section 2.2 “Assembly Steps” for drive replacement steps.
        • NOTE: The OWC ThunderBay 4 mini 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.

    3.3 OWC Disk Performance

    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.
