Disk drive size format on Dell Inspiron 14r (5437) Laptop

I would like to upgrade my HDD to SSHD drive.

Planning to purchase a 1TB Seagate SSHD 9.5mm version. (Two platter)

However, the stock harddrive is 500GB Seagate thin momentus version which is 7mm version. (Single platter)

Is it possible to install a 9.5mm 2.5 inch SSHD from seagate. I am afraid that the harddrive would not fit into it.

Anyone installed a 9.5mm harddisk inside before? Please report. Thanks!
