ok thanks but when I test the t7 shield on my windows PC, I get hat full 1000 mb/s speed. On macbok pro I get 850 read and 350 write according to Blackmagic. timing it manually on Mac, I can get about 650 write speed when transferring files. reading about this somewhere it seems that the MacBook TB4 and USB4 cause some sort of limit for usb drives so I was wondering since the Mac Studio max has only USB4 ports in front, if those perform at full speed potential since its not a mix of TB4. would be nice if someone could test the actual read and write speeds on those because if they are faster than the studio max is better than the ultra for this feature.
Some Macs and some devices only connect at 5Gb/sec instead of 10Gb. One such device is the Samsung T5 on M1 Macs. If this is happening with your T7, then lower speeds would be expected.
No. That was the Intel "Titan Ridge" JHL7540 controller probably: one controller for two ports. The Apple Silicon TB4 controllers are on the SoC, and theres one for each port. 4x for the Pro/Max and 8x for the Ultra (but only the Mac Pro has all 8)
Based on what I've seen in many threads, the Mac implementation of USB 3.1 gen 2 yields somewhat slower data transfer than the typical Windows/Intel speeds. Usually, though, the speeds are about 86-90% of the Windows speeds, like you are seeing for read, but not the severely lower 350 write you are seeing.
this is the reason why I no longer buy 1st gen products form Apple. They got me good with the first Apple Watch. I think I'll buy the 3rd gen studio because its usually the 3rd product that ends up being refined.
