Question about Lenovo 40AC0135CH ThinkPad Thunderbolt 3 Dock

Hi, I have the docking and it works with all laptops - except my Lenovo ThinkPad =). Mac, various HP laptops - all are loaded and work as desired. Whether connecting the hard drive via Thunderbolt is really faster is the question. Most external hard drives I know (or want to pay for) have the same transfer speed anyway whether USB (C, USB 2.0 is already lame...) or Thunderbolt. There are very few that have the real TB chipset and then the vast majority of (again, affordable) SSDs are only up to 500 MBit/s and not in the region of 3000 MBit/s....
So if your hard drive is not an exorbitantly expensive SSD, then you can connect it to the Lenovo docking no matter how. I also use it for RAW editing and have a TB SSD, but it's also a "slow" one and I don't notice any difference if I connect it via TB or USB... Even if I connect a "slow" but large classic hard drive to USB A or to the USB C port, there is no noticeable difference.

I don't know the Surface Dock, but I don't think it should be any slower than this docking. Ultimately a matter of taste. I'm a little disappointed by the number of problems this ThinkPad dock causes.... Sometimes it loads, sometimes it doesn't. Sometimes it recognises disks, sometimes it doesn't. What's the point of plugging the keyboard into the USB port? I'm constantly plugging it back and forth until something works. It's simply enough to make you cry.... And the only thing that never works is the Lenovo ThinkPad for which I actually bought the docking.... So I don't really know if I would advise you to buy this docking or if I would choose the probably better fitting Microsoft product =)
