Toughbook cf-30 second hard drive

Hi All,

I just bought a Toughbook cf-30 MK2 off ebay, which is my first Toughbook. Since It comes with a 80 gb HDD,
I'm considering adding a 128 gb SSD for a bit more space and performance. The best option for me seems to be
using one of these optical drive to hard drive adapters. Since I'm an absolute newbie to Toughbooks, I'd like to know
If there are any specific considerations on choosing an adapter or any suggestions for a particular type/brand?

Thanks,
