Slow external drive

Thunderbolt with Ventura slower than the previous version by almost 1/2 the speed. I have both a 10Gbps Ethernet adaptor that was working at 12Gbps to an external NAS and is now working about 4Gbps and an external SSD connected to direct to MAC via thunderbolt that was working at about 12Gbps and is now working at 3.2Gbps. --Only change was the upgrade to 13.1.

External Drives Extremely Slow Ever since the update to MacOS Ventura, any external drives I connect to my mac have been running extremely slow. This is true for both external hard drives connected via USB-C and SD Cards. I am on a 16" M1 Pro.

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

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]
