I would like to see if it is quicker to import photos directly from my camera, or using a card reader. Is there any way or recording the time taken for an import in Lightroom Classic?

Card reader is mostly the fastest. Time taken is a standard issue in Lr. Look at the menu's and options!!!

I expect the card reader to be fastest, but I would like to know how much faster, hence wondering if the time taken for the import is recorded anywhere. I was not able to find it in the menu/options.

Use a stopwatch...

I was hoping for something a bit less hands on - but will use green recording to capture it.

Time taken is in your metadata. And you can use it as a start of your export-filenames.

That is the capture date/time. Not the time it took to import the batch of images.

Camera USB is mostly USB 2, 480 Mbit/s, the USB 3.0 of modern card readers is 5 Gbit/s, ones that can plug into USB 3.1 is 10 Gbit/s.

I believe both my camera and the card reader are USB3.

It depends on the read/write speed of the yous device and how your OS behaving with them.
There are no menu options provided in Lightroom Classic to find the performance numbers automatically. 

Thanks,

Thanks for confirming. I am hoping to find the speeds of my devices, but will look into another way, such as screen recording the import.

As Johan suggested, just time a certain batch and import them once with the camera and once with the cardreader. When there is no substantial difference it does not matter wich of them you use

I was hoping that there would be some diagnostics/logging in Lightroom to do the timing, but will now look in to other methods.

There are milliards of apps to measure the I/o drive performance. Since activity monitor of macosx, task manager of windows, cinebench (your camera must config as mass storage). Iostat, bonnie, phoronix...


But im sure no camera beats an ultra udma CF plugged to a pcie, usb3, usb-c or thunderbolt reader. My most Is 120MB sec and is not the fastest one!

I will check out some of these apps, the problem is my camera cannot be configured as mass storage.

As there was no way to record the import time directly, I did a screen recording of importing 200 raw files (10.09GB)  - using both a card reader (4m02s) and direct from my camera (5m02s).

Most computers will have a way to display the Disk read/write speed the OS is doing. You could open up your system's performance monitors (on Macs this is Activity Monitor) and set it to show disk read/write speed during an import. With my XQD card adaptor I easily get 400Mbyte/second. Directly connecting the camera even though it does USB-c, I don't get near that.

The time for copying the images from the card to your hard drive is relatively short, depending on how many images are being copied and the speed of the reader or camera and the speed of writing to the drive they are being copied to. The slowest piece of hardware being the determining factor.
What takes the most time is for LR to create preview for each image. If you set LR to use the Embedded JPGs as the previews then it shorten the import time considerably.
