While I don't have an answer for you, it's hard for me to imagine that the problem is USB 3.0 vs USB 2.0. Even if your drive is operating at USB 2.0 speeds, the problem has to be something else. The speed of your disk drive cannot cause this problem (unless the drive itself is seriously malfunctioning), and so Firewrie or Thunderbolt or whatever isn't likely to fix the issue.
Lots of people in these forums have reported extremely slow (or the process stops part way) importing from Aperture. You might want to search for those threads.
My aperture importer plugin has been working away for about 90 hours now and is still on 23% .
By the way, does this mean it appears to have stopped at 23%, or does it appear to be still moving slowly and the percentage is slowly increasing?
I've read every post about importing from Aperture to Lightroom on the internet!
No it hasnt stopped. Amazingly it's still going, steadily...
Is the USB card on the main computer USB 3.0 compliant also.
still going, slowly — I would let it go
Naturally, there's more going on than simply transferring the photos from somewhere on one disk to somewhere else on the other disk. The Aperture "catalog" has to be "converted" to a Lightroom Catalog, and that doesn't depend on disk speed at all, and that could be where the issue lies. In addition, Lightroom has to generate previews of your images, and that doesn't depend on disk speed either.
Since you didn't tell us how fast your CPU is, and you didn't tell us how much memory your computer has, and you didn't tell us how big a typical photo are in megapixels (not megabytes, which is useless information in this context) all I can say is that it sure sounds slow, but who knows, really?
my processor speed is 2.9Ghz Intel Core i5, my memory is 16GB 1600 MHz DDR3, my graphics card is Nvdia FeForec GT 750M 1024 MB, but I have no idea what the average megapixel size is. How am I to find that out? I don't take huge photos, and I never process RAW ones. I am just as far as I know dealing in jpgs. I am an amateur.
I have no idea what the average megapixel size is
I asked for typical size, not average. You go to one photo, and you determine how many megapixels it is (or alternatively, the pixel dimensions in width and height)
well "typical" and "average" could be understood to mean the same thing in this case. I opened one image in photoshop to find out. it was 2448 x 2448, 72dpi. Taken on the iphone. Many of my pix are taken on other cameras, which may have larger dimensions.
So, I admit to being stumped, I have no idea why this is taking so long, nor do I know how to determine the problem. As I said, other people have similar complaints, but I'm not aware of a solution.
So ,I thought you all might like an update to my snail-pace import situation using the Aperture plugin. It was importing for a week and day and got to 31% - then unfortunately my computer suddenly crashed - I was asking it to do too many things at the same time.
I was interested to see how Lightroom had coped with the crash - I thought most likely Lightroom would not have managed to put in metadata or even remember any of the photos, let alone put them into correct project folders, but it has!!!
However - that is not of any use to me if I can't work out which photos from Aperture it has NOT YET imported, so that I can import them. After all, Aperture still has 69% of my photos still not yet imported into LIghtroom.
I don't know if the %31 of photos were moved or just copied out of Aperture (I have to try and check)
Can anyone think of a way I can now get the 69% into Lightroom manually, when I don't know exactly which they are? Otherwise Im going to get into mega confusion switching between albums in Aperture and Folder structure in Lightroom, trying to compare them!!!
