When I saw it was neither of those, I presumed the cloud storage service had been named in the same way razors are named, i.e. "puts you in the driving seat" sort of thing.
It was only several hours later did it occur to me that, OMG, they mean like a FLOPPY DISK DRIVE? Yikes.
"Drive" is not really a word I've heard used in relation to storage for years. Mainly because we only think about the distinction between disk and drive when the two can be parted, like a floppy disk drive. Put the disk in the drive. Most removable media is USB-based these days, so the term isn't used.
I guess in 1990s-era Windows NT networks you'd be told to save your work to "the M: drive" or such, but yeah, 1990s.
To me it's a moronic product name. "I'll save that to my Google Drive!" Sure thing, you do that Grandpa.
