- 2.5-inch or 3.5-inch SATA drives accepted in all 8 bays.
- Front USB ports can connect at up to 10Gbps even though they are Type-A ports (USB 3.2 Gen 2).
- Thunderbolt device chains can support up to six Thunderbolt devices.
- By using the DisplayPort feature, the overall performance of the drive may decrease somewhat, as the DisplayPort shares bandwidth with the Thunderbolt 3 ports. The same is true if you connect a display to one of the available Thunderbolt 3 ports (this can be done with either a native Thunderbolt 3 display or with a Thunderbolt 3 display adapter).
- Thunderbolt 3 is backwards compatible with Thunderbolt 2 and Thunderbolt, but speeds can be impacted depending on where in the chain a device is connected. If mixing Thunderbolt 3 with Thunderbolt 2 and/or Thunderbolt devices, use the device order shown below, if possible. Computer > Thunderbolt 3 devices > Thunderbolt 2 devices > Thunderbolt devices.
- SAS drives – Use of SAS drives requires the installation of a PCIe SAS controller (sold separately).
- To ensure no data is lost during normal use, always eject or unmount the corresponding disk(s) from your operating system before powering off the device. Several options are provided below for Mac.
- Drag the icon for the disk you wish to unmount to the trash can; OR
- Right-click the disk icon on the desktop, then click “Eject”; OR

If you purchased the ThunderBay Flex 8 with drives, they have been installed prior to shipment — please skip to the notes at the end of Section 2.2 Quick Start. If you are installing your own drives, follow the steps in Section 2.1 (below) to install 3.5-inch hard drives into your ThunderBay Flex 8 enclosure, or to replace existing 3.5-inch drives. Note: it is possible to install 2.5-inch SATA or U.2 drives (U.2 supported in top 4 bays only) using the fine-threaded screws that are included and the four screw holes on the bottom of each drive tray (highlighted in step 5 below).
2.1 Drive Installation
1. Insert one of the included keys into the lock on the upper right of the faceplate.
2. Turn the key clockwise, then pull it towards you. The faceplate will swing open.
3. Once the faceplate has swung open as far as it will go, lift to remove it.
4. For each tray you wish to remove, turn the thumbscrew counter-clockwise until you no longer feel resistance. Then hold onto the thumbscrew and pull the drive tray out.
5. Set the drive tray on your work surface as shown. If you are replacing an existing hard drive, unscrew it from the drive tray at this time. Note: the highlighted screw holes are for 2.5-inch drives (SATA or U.2). The holes for 3.5-inch drives are highlighted in green (Step 7).
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 six of the included screws (three per side). 2.5-inch drives require four of the fine-thread screws.
8. Slide the drive tray back into the rails in the ThunderBay Flex 8 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 try again.
2.2 Quick Start
- Install drives into the ThunderBay Flex 8 according to the instructions in Section 2.1 Drive Installation. if you have not already done so.
- Connect the power supply between the ThunderBay Flex 8 and a power outlet.
- Connect the included Thunderbolt cable between the ThunderBay Flex 8 and a computer. When you do this, the device will power on and the drives will be available for use on the computer.
- NOTE: If you installed your own drives in the previous section, they need to be formatted before you can use the ThunderBay Flex 8.
- This product shipped with a license for SoftRAID, which is recommended for setting up RAID volumes and working with ThunderBays. If you purchased your solution with drives, they were already formatted as a RAID volume, but you should still install SoftRAID to get the best performance and functionality.
- If you do not wish to use SoftRAID you can visit Drive Formatting / Data Migration Tips and use one of the Mac specific links for instructions on formatting your drives.
2.3 Installing a PCIe Card
1. As you face the front of the device, the side-panel on the left needs to be removed. Use the included hex key to loosen and remove the four fasteners holding the panel in place.
2. Remove the side cover and set it aside.
3. Remove the PCIe slot cover then set the screw aside. Store the slot cover; it will not be needed to complete this installation.
4. Align your PCIe card’s connector with the open slot then install the card as you normally would when installing into a desktop computer.
5. Use the screw from Step 3 to affix the card’s bracket to the case.
6. If your PCIe card has I/O Ports, double-check the back of the device to ensure the bracket is level / that none of the ports are obscured by the plating on the back of the case. If needed, loosen the screw you set in Step 5, re-align bracket as needed, and re-tighten the screw.
7. Set the side cover back on the case, making sure the holes are aligned with the four fastener holes, then re-affix the four fasteners removed in Step 1.

2.5 Changing Drives & Drive Failure
You can add or remove any drive without needing to turn off the device or to unmount any of the other drives. Each drive operates independently of the others and is not affected by the addition or removal of another drive unless you set them up as members of a RAID array.
By itself, the ThunderBay Flex 8 does not monitor drive health or alert you to a drive failure. You can monitor the health of your drives via SoftRAID in order to determine when a drive has failed or is in a pre-failure state. To replace a failed drive, simply remove the drive from its bay and replace it with another drive, following the steps in Section 2.1 Drive Installation. The device does not need to be powered off during this process.
Begin troubleshooting by verifying that the power cable is connected to the ThunderBay Flex 8 and to a power source. If the power cable is connected to a power strip, make sure that the power switch on the strip is turned on. Then, verify that the Thunderbolt 3 cable is properly plugged into the computer and the ThunderBay Flex 8.
If the ThunderBay Flex 8 is still not working properly, try connecting to another computer or using another Thunderbolt 3 cable. When the computer goes to sleep, the ThunderBay Flex 8 will go to sleep. If you are still experiencing problems, consult to 24/7 Support Chat.
