T450s 3rd M.2 Ssd Slot

Posted on  by

T450s - Help regarding installing SSD later on. So looking at T450s configuration, I have following options: Hard Drive: HDD OR. Micro Harddrive. 16GB m.2 NGFF SSD. System Expansion Slots: No Smartcard Reader OR. 3rd M.2 SSD slot OR. Smart Card Reader. I want to go for 500GB HDD, but want to make sure I can install another SSD. I inquired the seller about the 3rd M.2 slot, and the seller is not sure about it. From what I have read, every T450s can have up 3 drives, one 2.5 drive and 2 M.2 drives. Is that a correct understanding? Is the 3rd M.2 SSD slot available already? I know if I order a CTO one, I have to specify a 3rd M.2 slot.

I currently use a T530 with two storage drives (mSATA and SSD), but this laptop is a bit too bulky for me to carry around the office so I am considering the T450s.
On the Lenovo US site, this laptop is configurable with three storage options:
1. Normal SSDT450s 3rd M.2 Ssd Slot
2. 16GB M2 SSD (pre-installed)
3. (optional) 3rd M2 SSD in place of the smart card reader.
Here is where I have some questions:
1. I am not sure if these parts are field replaceable (like the mSATA slot on my T530) or do I have to configure it online.

2. What kind of SSD fits in these slots? M2 is just the name of an interface which can support many sizes of cards.

4. Is it possible to select individual drives for booting; as on the T530 where each drive appears in the boot device options menu (F12 key during startup).
