Traditionally, a recovery partition needs to be on the C: drive because that's where the recovery software expects it to be. If it's moved to another drive (which will have to have a different assigned letter) the recovery process probably won't work.
One of the drawbacks with a recovery partition and the recovery software is if it has to be used, everything that had been installed on the hard drive (other programs, files, folders, etc) will be erased. Also, any bloatware, trial programs, installed by Dell will be back on the machine. To get around this many people use system imaging instead. An image is like a snapshot of the hard drive. Everything is copied to the image; the operating system and all personalizations, all files, folders, documents, photos, music, etc. The image can restore the computer to the exact condition it was in at the time the image was made. Unlike the recovery partition which restores the machine to the way it was when it left the factory. It saves hours, if not days, of reconfiguring the computer.
There are also programs available that can migrate an existing hard drive to an SSD, even if the SSD is smaller than the original HDD. One of the highly rated programs is from Paragon. It costs $20 but pays for itself in one use considering how much time would be involved in moving data from a HDD to a SSD the old fashioned way. Not to mention the added time to set everything up.

You could set up your machine on the HDD and make a system image which would include the recovery partition, operating system, all additional programs, etc. Migrate to the SSD, eliminate the recovery partition, set up the SSD with your personalized settings, and then image the SSD. If you ever need to go back to the HDD you've got it's image. If, for example, the SSD becomes infected with malware you could use the SSD image and be back up and running in about 30 minutes or so.
