HDD caddies for laptop at 12.7mm - do they even sell 2.5" at that size?

I ordered an HDD caddy for my HP elitebook, can be seen here:

The thing is, this caddy (and all of the caddies I've seen) advertise a 12.7mm maximum size, but when I search for that size of 2.5" drive, it seems that they are not even sold anymore above 9.5mm. It seems if there was a 12.7mm drive, maybe it would fit better in caddies like this and give more memory/performance for the price, however I can't even find them for sale, so what's the point?

Long story short - is there such a thing as a 12.7mm 2.5" laptop hard drive?

Toshiba used to sell a 1.5TB 5400RPM 2.5" 12.7mm SATA HDD.

I use one in a DVD-bay-HDD-tray to back up my laptop.

I got mine by pulling apart a ($60) Toshiba Canvio portable USB hard disk. Your experience pulling apart USB hard disks may vary, especially since most 2.5" portable hard disks now have USB soldered onto their PCBs.
