Test Bed:
CPU - Intel i5-6500
Motherboard - GA-Z170-HD3
Memory - 2x 8 GB DDR4 2600 MHz
GPU - Zotac GF 9600 GT 512MB
OS - macOS 10.12.2 (Clover v3763 boot with config.plist>kexts>Other with USBinjectAll.kext and FakeSMC) also see attached config.plist if interest in the patches.

Test Items:

SSD - Crucial MX300 525 GB (2 1/2 inch form factor - Black Friday purchase)

USB Type C PCIe Card - dodocool DC22 PCIe card (Amazon $23 USD) https://www.amazon.com/gp/product/B01C59TB0I/?tag=tonymacx86com-20

Type-C Adapter Cable - SABRENT EC-HDSS 2,5” SATA HD/SSD to USB Type C adapter (Amazon $17 USD) https://www.amazon.com/gp/product/B014T3JRFM/?tag=tonymacx86com-20

I installed the dodocool card into the second PCIe 16 slot (the one farthest from the CPU) and booted to the previously installed macOS.

The system boots with the dodocool PCIe card without issue. I attached the Crucial SSD using the SABRENT SATA to Type C adapter to the Type C port. Then used the Disk Utility.app to format and partition the drive into one partition (of course there is the hidden EFI partition not used in the testing).

Then I cloned the boot partition to the external USB SSD. Re-booted to the SSD on the Type C port.

The boot to the dodocool Type C port attached Crucial SSD is quick and the overall system performance is smooth.

Of interest is the Blackmagic Disk Speed Test result:

And then swap the Crucial from the external connection to the internal SATA connection and boot to it:

Hummm just about the same performance but where the Crucial SSD booting from the dodocool Type C port is a little faster.

Okay what else can I do? How about the Crucial SSD attached via a standard SATA adapter with a USB 3,0 type A connector connected to a motherboard USB 3.0 port. This resulted in a hang boot with the stop sign error icon.

Then attached the Crucial drive to the USB 3.1 Type A port on the dodocool card and booted okay. However the speed is down a little.

With this system report on the USB section:

Of interest the offered load from the Crucial SSD is probably about 4+ Gb sec. so we are not able to fully load the pipe with this set up. I mean that with this gear I can not produce a data stream that approaches the implied through put.

Well in summary there are no big surprises with this PCIe USB Type C add-in card. Worked OOB and does what I expected it to do.

This is on a current tech rig. With “old tech” , the set up was not bootable on my EX58 rig that has a dated BIOS and legacy Clover boot.

Good modding,

Hi Neil,

What did you have to do to get your card to show up as a USB 3.1 device? I have the card with 2xType-C connectors ( https://www.amazon.com/gp/product/B01JGJ8J0I/?tag=tonymacx86com-20 ) and it does not show up as a USB 3.1 card, and the transfer rates I am getting with it are about 37MB/s vs closer to 500MB/s that I would expect with a Samsung T3 drive.

Do you have suggestions on steps needed for this card to operate at full speed?
I am using Sierra 10.12.5
 
Is this the card? Your Amazon link no longer works, but I found the card on the dodocool site.
The page says it has a ASMedia ASM1142 chip. Ableconn sells a similar card Their page says

It works on Mac OS X 10.9 to 10.10 and 10.12 to 10.13, but does not work on OS X 10.11.

Is this true? Does the ASM1142 chip not work in El Capitan?
