| Can I get a longer cable for the CFast 2.0 Pro Card Adapter? | Oct-24-17 |
| The CFast 2.0 Pro Card Reader is Thunderbolt certified with only the 0.5 meter 40Gb/s passive cable that is attached at the factory or a Sonnet-authorized service center.
To achieve a longer reach from the computer to the Reader, you may attach the Reader to the pass-through Thunderbolt 3 port of a two-port Thunderbolt 3 device that has a longer Thunderbolt 3 cable to the host computer.
If you absolutely must have a 1-meter cable, and you don't have another device to daisy-chain, then a 1-meter 20Gb/s cable will work. A 20Gb/s cable will not compromise the perfomance of this reader.
Do NOT use a 1-meter 40Gb/s cable under any circumstances. A 1 meter 40Gb/s cable has active electronics, and the power requirements of this reader combined with the active electronics in a 1-meter 40Gb/s cable would exceed the Thunderbolt 3 power specification. Furthermore a 1 meter 40Gb/s cable has a longer connector that will not fit behind the rear panel.
Do NOT use a 2-meter cable under any circumstances. There would be too much voltage drop in a 2-meter cable for this Reader. |

| Can I connect the CFast 2.0 Pro Card Adapter to a Thunderbolt 2 Mac? | Oct-24-17 |
| Thunderbolt 2 does not have enough power to directly connect a Thunderbolt 3 bus-powered device like the CFast 2.0 Pro Card Reader. However, you can connect the CFast 2.0 Pro Card Reader if you have an intermediate Thunderbolt 3 device in the chain that is wall-powered, for example the Sonnet SxS Pro Card Reader.
Thunderbolt 2 Mac----Apple TB 3 (USB-C) to TB 2 Adapter----Wall-powered Thunderbolt 3 Device----CFast 2.0 Pro Card Reader
Note that the Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter is reversable and will support a Thunderbolt 2 Mac and a Thunderbolt 3 device (as well as a Thunderbolt 3 Mac and a Thunderbolt 2 device). |

| Some cards, notably 960GB Angelbird or RED cards drop offline. | Oct-11-21 |
| These cards draw more power than the official specification. Sonnet has revised the CFAST reader to accomodate these cards. The original CFAST Reader had serial number starting with "A". Modified CFAST Readers have a serial number starting with "B". Sonnet is offering a free upgrade from A revision to B revision for customers with this issue. |
