1.1 Minimum System Requirements
• Mac: host with Thunderbolt™ 3 port running macOS 10.13 or later
• PC: host with Thunderbolt 3 port running Windows 10 or later
1.2 Package Contents
• OWC ThunderBlade V4
• 0.5m Thunderbolt 3 cable
• Power supply and cable
1.3 Getting Started
• To use the ThunderBlade V4, connect it to your computer via the included
Thunderbolt 3 cable. Device drivers are not required, however use of
SoftRAID XT (macOS only at the time of this writing) requires the SoftRAID
driver and application.
• The LED indicator on the front of the device (see Section 1.5) will glow blue
when the device is receiving power and is connected to an active host.
The LED will glow white when the device is connected to a host that is in
Sleep or hibernation mode, or when it has power but is not connected to a
host. This LED is also connected to a light sensor on the back of the device;
this enables the LED brightness to adjust automatically based on ambient
lighting conditions.
• The LED has four segments, one for each installed M.2 SSD. When
one or more of the SSDs are accessed for read/write operations, the
corresponding segments will blink blue.
• While it is possible to connect a DisplayPort 1.2 display to the spare
Thunderbolt 3 port on the device by using the appropriate cable or adapter,
HDMI and other types of displays require an active display adapter with a
USB-C host connection.

2.1 Mac Formatting & SoftRAID Information
The pre-installed SSDs have been formatted as a Journaled HFS+ volume for
Mac, and congured as a RAID 0 using SoftRAID XT. While you can use the
drive without SoftRAID XT installed on your Mac, we recommend you download
the application at softraid.com/srxt and install the latest version to get the best
performance. The OWC ThunderBlade V4 ships with a license for SoftRAID XT; the
serial number is on the bottom of the device.
2.2 PC Formatting Process
Note: all data on the ThunderBlade V4 will be lost when following the steps below.
Back up all important data before proceeding.
1. Connect the ThunderBlade V4 to a Windows 10 host using the included
Thunderbolt 3 cable, then connect the included power supply.
2. When the ‘New Thunderbolt devices...’ dialog appears (shown below), click
OK. Note: if you are using Windows via Bootcamp, the dialog box noted in
this step may not appear. On some PC systems, a secondary dialog may
appear after the ‘New Thunderbolt devices’ dialog and before the dialog
shown in Step 3, asking if you want to allow ‘Thunderbolt Software’ to make
changes to the device. Click ‘Yes’ in that case.
3. The ‘Approve Thunderbolt Devices’ dialog will appear. Choose the ‘Always
Connect’ option from the menu (shown below) and then click OK.

First-time SSD Users

6. You now need to clean the disks (this will require you to step through the

we’ll use Disk 2 (i.e. the series is disks 2-5). At the DISKPART > prompt type
‘select Disk 2’ and press Enter. You should see a message that the disk
has been selected (as shown below). Next, at the DISKPART > prompt type

then be asked by Disk Management if you are sure you want to continue.
Click ‘Yes’. Once the formatting process is complete, the ThunderBlade V4

and RAID 0 setup process.
Notice: Windows 10 does not currently have a method of ejecting
Thunderbolt storage devices. Before disconnecting the ThunderBlade V4

3.1 Troubleshooting
If your computer does not recognize the drive when it is connected, make sure
the cable is attached securely. You can also try plugging the cable into a dierent
Thunderbolt 3 port on your computer and/or trying a dierent Thunderbolt 3 cable.
PC users: if you have opened Disk Management but do not see the ThunderBlade
V4 SSDs listed, make sure you followed all the steps in Section 2.2 from the start.
Multiple permission steps are required for a PC to communicate properly with
Thunderbolt 3 SSDs; skipping one or more of those steps may result in the disks
not being visible in Disk Management.
3.2 About Data Backup
To ensure your les are protected and to prevent data loss, we strongly suggest
that you keep two copies of your data: one copy on your OWC ThunderBlade
V4 and a second copy on either your internal drive or another storage medium,
such as an optical backup, or on another external storage unit. Any data loss or
corruption while using the ThunderBlade V4 (including with SoftRAID XT) is the
sole responsibility of the user, and under no circumstances may OWC, its parent,
partners, aliates, ocers, employees, or agents be held liable for loss of the use of
data including compensation of any kind or recovery of the data.
