yeah, borderlands 3 finally on fixed 60fps + vsync on high quality 1080p. Previously it was barely making 30 fps on medium!
The whole system even heats up much less. Stays quieter. Much less portable now though Smile

Connected it internal port:

Did you want to create a separate build for the M.2 interface eGPU link with the SSD swapped into the TB2 enclosure?

The large block bandwidth performance you see is considerably faster than TB2. Moreso when evaluated across all block sizes as per sig. A worthy build option for these older MacBooks with a M.2 slot.

@mbp2014ftw, That looks good and it's closer to Thunderbolt 3 throughput than Thunderbolt 2.

You mean closer to Thunderbolt 2 (slightly greater than Thunderbolt 2) throughput than Thunderbolt 1? 796 MiB/s is from Thunderbolt 1. 1552 MiB/s is from whatever is inside the 2014 15"  MacBook Pro 11,2 (either PCIe 2.0 x4 or PCIe 3.0 x2?) and is a little more than Thunderbolt 2 (1283.55 MiB/s). Thunderbolt 3 is almost 1000 MiB/s more than the 1552 MiB/s number.

You mean TB1 enclosure? The jetDrive is Thunderbolt 1. A similar TB2 enclosure might not exist. A TB3 enclosure could be connected to a TB3 dock that is connected to the MacBook Pro with a Thunderbolt 3 to Thunderbolt 2 adapter.

Where is large block bandwidth mentioned? Block sizes? I is confused.

Hey, yeah, I can create a separate build page for the internal.

1552 MiB/s is from whatever is inside the 2014 15"  MacBook Pro 11,2 (either PCIe 2.0 x4 or PCIe 3.0 x2?)

According to ^ it is PCIe 2.0 x2

@mbp2014ftw, then where'd the 1552 MiB/s come from? PCIe 2.0 x2 is only 1000 MB/s. Does this mean the M.2 device is PCIe 2.0 x2 but the M.2 slot is PCIe 2.0 x4?

The Late 2013 and Mid 2014 MacBook Pro laptops both support all generation 3 drive options, and as with the MacBook Airs, while the included drives were PCIe 2.0 x2, the logic boards all support four channel PCIe connections.

Okey so i read on the adt R43SG-TB3 adaptor link on aliexpress that it is not compatible with TB2 adapter, So how did you do this with TB2, I want to buy a TB3-TB2 adapter and then Add this R43SG to work with my Macbook air 2017 which has a TB2 interface will it work ?

@abdullah_khan, the R43SG-TB3 is being used without the TB3 part (you can also buy the R42SG without the TB3 part). Instead, the M.2 part is connected to a Transcend TS480GJDM825 SSD which is a Thunderbolt 2 NVMe enclosure.

The Transcend JetDrive 825 enclosure uses an Apple connector so it also needs an adapter for M.2

I wonder if the Transcend adapter fixes the 3,3V problem also for solutions not using an ATX PSU.

 

I wanted to build a cheap TB1/2 enclosure for a while, to give to my girlfriend for playing sims on windows on her macbook.  

Wanted to keep it as compact as possible, to save space on her desk, so i would be using this very minimalistic adapter (it has x4 lanes and sata power input): https://de.aliexpress.com/item/32861465503.html   and a high efficiency external PSU like this which i have still lying around: https://www.fsp-ps.de/en/product/adapter/1489439229-430.html  

Maybe i need a step down board for 5v (is 5V even needed?)

Currently the problem seems to be that all those M.2 Thunderbolt 3 Adapters do not work with Thunderbolt 2 because the Apple adapter does not have the necessary power delivery for those m.2 to PCIe adapters.  I suppose it is about the 3,3Volt, which is why the R43SG fixes it by using a ATX Power supply and also onboard mosfets if Using the Dell 12V PSU.

 

But this transcend adapter must somehow be able to handle the 3,3V power request for the M.2 SSD also from the Thunderbolt 2 Cable.

 

Also the Apple adapter add to the cost and makes for a messy cable arrangement, which is why i would prefer the transcend solution.

 

@Threadstarter mbp2014ftw would you mind trying out the setup with only 12V supplied to the board? Do you know if the Transcend adapter supplies the necessary 3,3V for the PCIe or if it is the ADT Adapter?

@maksdampf, that M.2 to PCIe x4 adapter with SATA power doesn't appear to have a voltage regulator. It might use 3.3V from SATA, but more likely it will use 3.3V from M.2 because it will assume that some SATA power supplies don't include 3.3V.

There exist M.2 to PCIe x4 adapters with a voltage regulator. They use 5V to make 3.3V.

Maybe you can use a 12V to 3.3V voltage regulator if the 3.3V from the M.2 slot is not sufficient.
