T450 hard drive upgrade options?

Been out of the loop since my T430s, now was thinking to get T450 since I see a few good deals. I noticed Lenovo complete revamped their line up with no external optical drive for 450 (thus, no caddy option for a 2nd drive) and you need to take the whole laptop apart to get to the main hard drive (assuming 2.5" only, either 9.5mm or 7mm with an adapter?). Here is a dilemma, T450 model I was looking into comes with 128GB ssd, good to run OS but not enough storage for media files. If I upgrade it to 1TB or 2TB (dirt cheap now under $100), all these high capacity drives only come in 5400rpm flavor. I seen some 1TB with 7200rpm but only in 3.5". Fine for storage, but 5400rpm going to cripple OS and running programs.

So what are my upgrade options? Does T450 comes with mSATA and can I upgrade it, or is there just a slot for it? If it does, wondering if I can get something like Sammy 850 EVO 250GB mSATA ($92) for OS and programs, and get 1TB or 2TB for storage (any recommendations?).

What do you guys/gals think?

 

In my T450s, I have a boot drive m.2 256GB SSD from MYDigitalSSD that you canget on Amazon. It is the 2242 size not the 2280 longer size. also, I have the 2.5 9.5 mm 2TB Samsung Mard drive in the 2.5 bay that I got from Anmazon to store my data. After removing bottom, it was easy to upgrade these parts at one time and then use Lenovo revoery USB stick that you make before to restore system to the SSD. Hope this helps and this is a fantanstic laptop.

Thank you for clarification. Though I'm looking at T450 instead of T450s, just confirmed T450 also has M.2 2242, no more mSATA. Thank you for the pointer! Also, looks like MYDigitalSSD is the most popular option, $83 for that one. Appreciate the feedback!
