My Moto v360 is slow also
I feel your pain, my Motorola v360 is slow at bluetooth transfers also! I can use a mini-usb cord but that is slow as well. Sorry, I don't know the transfer rate of my usb connection.
My v360 has a MicroSD slot and I have a 1GB card to replace the 64MB card that came with it. I put the card in an IOGEAR usb reader to get files on or off the card and it transfers relatively fast. Yes, it's a lot more fooling around than bluetooth or a usb cord but I usually only do it for transferring a lot of music or if I have a lot of pics or vids I took on the phone. I think I have about 600-700 MB on it right now.
However, I still use bluetooth to sync contacts with my PowerMac and my .Mac account using iSync. It's painfully slow but syncing with my PowerMac is so valuable to me.
One thing I have wondered about is the bluetooth version of the phone. I know bluetooth v2 adapters are available on the computer end but I don't know if phones are v1 or v2. V2 has a higher transfer rate.
Does the RAZR, SLVR or Pebl have a memory card slot?
