Connection speeds and LED's

The connection speed of the Compact Drive Reader depends on the type of USB connection and on the power that is delivered by the host.

We recommend to connect the Reader directly to a USB-C port that is capable of providing the maximum current allowed by USB-C (3A). The Compact Drive Reader will then provide a connection speed of 8 Gb/s (1 GB/s).

A USB-A port can only provide 0.9A and the connection speed will be limited to around 180 MB/s.

The available power is indicated by the status light on the front of the Compact Drive.

LED color	Power supplied	Speed
Blue	3A from host	Approximately 1GB/s
Green	1.5A from host	Approximately 550MB/s
Amber	0.9A from host	Approximately 180MB/s (In this case it is likely that the Compact Drive Reader is connected to a USB-A port.)

NOTES:
Please ensure you are using a suitable cable which provides full USB-C data transfer speeds. For example: An Apple 2m Charge cable is unsuitable. It will provide 3A power, but is restricted to USB-2 data transfer speeds.

A suitable cable for optimum performance will be a USB-IF certified type-C to type-C cable rated for 10Gbps (USB 3.2 Gen2), or a Thunderbolt 3 (passive type) cable.

USB 2.0 ports should not be used as they provide only 0.5A, which will result in poor and unreliable performance.

Connecting the Compact Drive Reader

When using a Mac:

Connect the Compact Drive Reader to the Mac host with the USB-C cable before booting the Mac,

or,

If the Mac is already booted, connect the USB-C cable to the Compact Drive Reader first and then to the Mac host.

Connecting on Mac with either of the above methods will result in the Compact Drive Reader receiving 3A for best performance. Please note that 3A may not be available to the Compact Drive Reader if other bus powered devices are already attached to the Mac.

If the cable is connected to the Mac host first, and then to the Compact Drive Reader second, it may only get 1.5A and have reduced performance.

Compatible cabling

The following cable types have been tested and are known to work with the Compact Drive USB-C Reader:

0.5m USB-C cable
1m USB-C cable
0.5m Thunderbolt 3 cable (passive type)
1m Thunderbolt 3 cable (passive type)

The quality of different USB-C cables can vary depending on the manufacturer. If you experience reliability issues then try another cable, or a cable from another supplier.

The following cables are known to not work correctly with the Compact Drive USB-C Reader:

2m Thunderbolt 3 cable (active type)

Use with a USB hub

We do not recommend that you use the Compact Drive Reader via a USB hub, as the power to the device is not guaranteed and this may result in reduced performance.

Using a Thunderbolt 2 > Thunderbolt 3 adapter

Do not use a Thunderbolt 2 > Thunderbolt 3 adapter. They do not pass USB signals and power in the required way. The Compact Drive Reader should be connected to either a USB-C or Thunderbolt 3 port.

Safely Ejecting a Compact Drive

Here are the recommended methods to eject a CODEX Compact Drive using macOS and Windows operating systems:

macOS
Using the Device Manager menu bar app, hover over Compact Drive - USB-C and choose the Eject option. Ensure you see the status Unloaded displayed in the summary , and that the LED on the media has stopped blinking. It is now safe to remove the Compact Drive from the Compact Drive Reader.

Windows
Use the Safely Remove Hardware option in the taskbar to ensure the Compact Drive is safely unmounted. Ensure the LED on the media has stopped blinking. It is now safe to removed the Compact Drive from the Compact Drive Reader.

PLEASE NOTE: Removing CODEX media from a Media Station without ejecting it properly could result in data loss.

Compact Drive Readers with Apple Silicon Macs and macOS 12.3 and below

Due to compatibility issues with the Apple Silicon architecture and the USB chips used in the original Rev A Compact Drive Reader, if one of these Compact Drive Readers is used on an Apple Silicon Mac with macOS 12.3 and below, when data is read from the Compact Drive the transfer will stall or fail.

This issue is known to affect all Apple Silicon Macs including M1, M1 Pro, M1 Max , M1 Studio and M2 running macOS 12.3 and below.

Improvements with macOS 12.4 and above

CODEX has worked with Apple to identify a workaround for this issue, which has been applied to macOS 12.4 and above. With macOS 12.4 and above the Rev A Compact Drive Reader will now work on Apple Silicon Macs, but with limited performance (around 600 MB/s).

The change in macOS 12.4 will also temporarily affect the Rev B Compact Drive Readers, which will also then operate at this reduced speed on Apple Silicon Macs until they have a firmware update applied (see Firmware Updates and Device Manager section below).

The change in macOS 12.4 applies the same whether the Compact Drive Reader is directly connected or looped through another device to the Apple Silicon Mac.

Firmware Updates and Device Manager

Device Manager 6.1.0 (available on the CODEX Software Downloads page) and above includes a firmware update that can be used on Rev B Compact Drive Readers to restore full performance when used on an Apple Silicon Mac with macOS 12.4 and above.

With Device Manager 6.1.0 and above, a notification will prompt you to update the firmware on a Rev B Compact Drive Reader if necessary.

With Device Manager 6.1.0 and above, a notification will inform you when a Rev A Reader is connected to an Apple Silicon Mac with macOS 12.4 and above that it will run at limited speed.

For information on updating firmware, please see the Updating Firmware section below.

Support

If you have any further questions or concerns about the compatibility of your Compact Drive Reader, please contact CODEX Support or email support@codex.online.

Use with a Mac Pro 2013

The Compact Drive Reader can be used with a Mac Pro 2013 model, or any Mac that has Thunderbolt 2 ports, in the following setups:

Connected to a Sonnet Allegro USB-C PCIe card, which is installed in a Thunderbolt expansion chassis such as the Sonnect Echo Express SE I. In this case the performance will be around 800 MB/s.
Connected to a CalDigit TS3 Plus, via the 10 Gbps or 5 Gbps USB-C ports. When connected to the 10 Gbps USB-C port the performance will be around 550 MB/s. When connected to the 5 Gbps USB-C port the performance will be around 375 MB/s.
Connected to a USB-A host port on the Mac Pro, using a USB-C to USB-A cable. In this case the performance will be limited to 180 MB/s.
The Compact Drive can be used with a Compact Drive Dock TB3 (CX.0001007) connected to the Mac Pro via a TB2 to TB3 adaptor (official Apple adaptors are recommended). This is the highest performance option for offloading data from the Compact Drive to the Mac Pro (2013) with a maximum rate of 1400 MB/s.
The Compact Drive can also be loaded into an Adapter (CX.0001009) to work in the Capture Drive Dock (CDX-75013-1) which connects to the Mac Pro (2013) via TB2. This is the highest performance option for offloading data from the Compact Drive to the Mac Pro (2013) with a maximum rate of 1400 MB/s.

The Compact Drive Reader cannot be used with a Mac Pro 2013 model in the following setups:

Connected directly to an official Apple TB3 to TB2 adapter, which is then connected to a TB2 port on the Mac Pro. In this case the Compact Drive will not load at all.
Connected to the loop through port of a TB3 peripheral or expansion device. In this case the Compact Drive will not stay loaded reliably and result in errors during the copy process. This includes connection to the TB3 downstream port of the CalDigit TS3 Plus.
