Does all Dell XPS 15 9550 models with 56Wh include a HDD slot?

[Melach]

I'm considering to order this laptop, it says it's got 56Wh of battery life, and has a 256gb SSD, but it doesn't include any HDD and neither does it specify anything about having a HDD slot. I just want to be sure before I actually order this laptop, does all 56Wh versions of this model have a HDD slot? Ty in advance.

Edit: Also, does anyone know how long a 56Wh battery life on a Dell XPS 15 9550 will last for normal use like internet browsing?

The Dell XPS has both M.2 and 2.5" bays for storage.

With the 56Wh battery you can install a 2.5" drive into that bay.

The larger capacity 84Wh battery will not allow you to use the 2.5" bay because it will be occupied by the larger battery.
