Samsung X5 Thunderbolt 3 enclosure with 2TB Samsung 2TB 970 EVO Plus NVMe drive (with new firmware 2B2QEXM7 released May 20, 2019) Benchmarks in left-sided Thunderbolt 3 ports on MacBook Pro. The Samsung X5 is my fastest Thunderbolt 3 enclosure. I am using the included Thunderbolt 3 cable which came with the Samsung X5 drive.

Although this drive is now stable with macOS, I am getting mediocre write speeds of 977 MB/Sec with multiple Mac and Windows benchmarks, compared to the Samsung EVO 970's write speeds of 1881 MB/Sec. The results are similar with macOS and Windows filesystems.

I'm wondering if any X5 users see significant drop off in performance if the drive is used on say the single TB3 bus on the newer iMacs (two ports, one buss as I understand it), where the other port is driving say a 4k display.

Ordinarily not an issue. It's a GPU issue. USB-C is just a port. Depending on the Mac, it can carry TB 1, 2, 3 or no Thunderbolt at all—even those can drive a 4K monitor.

The TB spec allows devices to be daisy-chained but a monitor must always be the last in the chain with TB 1/2. Apparently, with TB3, the monitor Ned not be at the end. The new LG TB3 4K allows it to be daisy-chaine.

So if say one is gaming while say doing something that also requires reading or writing a lot of data to the X5 neither suffers a slowdown? pretty cool. I had just assumed the pipe might get clogged, so to speak.

This thread is about the Samsung X5, which is a Thunderbolt drive. The T5 that you posted benchmarks for is a USB drive.

I'm curious about this as well. With one shared TB3 bus, if you boot from one slot and connect an eGPU to the other, aren't they eating from the same pool of bandwidth?
