Does USB 3.2 gen 2x2 HUB hub exist?

MacBook Pro M1 has only 3 type-c ports. I need more with the highest speed possible.

Does MacBook Pro M1 support 20 Gb/s transfer rate? (I.e does it make sense to buy external 20 GB/s case for my SSD which can provide such speed)?

USB 3.2 2x2 compatibility with M2 Pro Hello everyone, Is there a way to get the speed of 20 gbps on the MacBook pro M2 chip ( directly via Thunderbolt or a Hub) with an external SSD such as Kingston XS2000? If not then is it better to save some money and get a 10 gbps SSD such as Crucial X8 or SanDisk Extreme portable?

Crucial X10 SSD transfer speeds on Mac Studio slower than expected Hi, I've just received my new Crucial X10 SSD's and I speed-tested them expecting to get around 2000MB/s. Unfortunately, it was showing around 920MB/s. This is plugged into the Thunderbolt 4 USB ports at the rear, capable of transfer speeds of 40Gb/s (5000MB/s). The ports are also USB 4, and USB 3.1 Gen 2 as shown here - Mac Studio - Technical Specifications - Apple What I can't seem to work out, is why is the crucial drive only transferring at 920MB/s when the drive is brand new. It should be transferring at 2000MB/s as advertised (otherwise the X9 would have been a better buy). Although even if there is a ridculous apple thing where the USB 3.1 port is in action, instead of the USB 4, and the drive is only transferring at that 10Gb/s speed, that should be 1250MB/s, not the 920MB/s I'm seeing. Basically, is there someone more knowledgeble about port speeds that can explain why I'm not seeing faster transfer speeds? Thanks. [Re-Titled by Moderator]

MacBook Pro M1 Max Thunderbolt 4 Port Speed Issue Dear Apple Technical Support, I hope this email finds you well. I am reaching out to inquire about a potential issue I've encountered with my MacBook Pro M1 Max regarding the Thunderbolt 4 ports' speed capabilities. I recently acquired a Samsung T9 external SSD, which boasts a maximum speed of 20Gbps. To leverage its full potential, I connected it to my MacBook Pro M1 Max using both an Apple-branded Thunderbolt 4 cable and a USB-C 3.2 Gen 2x2 cable. However, despite these efforts, I have been unable to achieve the expected 20Gbps transfer speeds. Only 10Gb/s. Upon further investigation, it seems that the MacBook Pro M1 Max is not fully utilizing the Thunderbolt 4 ports' capabilities, as the transfer speeds remain capped at around 10Gbps. I would greatly appreciate your assistance in clarifying why the MacBook Pro M1 Max is not supporting the full 20Gbps speed on its Thunderbolt 4 ports, especially when paired with a compatible device like the Samsung T9 SSD. Is there any specific configuration or troubleshooting steps I should undertake to address this issue? Additionally, if there are any known limitations or compatibility issues related to Thunderbolt 4 connectivity on the MacBook Pro M1 Max, I would appreciate any insights or recommendations you could provide. Thank you very much for your attention to this matter. I look forward to your prompt response and resolution of this issue. Best regards, Miroslav Belančin
