mSATA for Lenovo T470s

Hi,
This is related to Lenovo Laptop T470s.
It uses mSATA for the storage.
There are 2 kinds of mSATA: M.2 and NVME
I am still confused which mSATA for the above laptop?

Thanks,
tjie

It could have either SATA or NVMe, see https://www.reddit.com/r/thinkpad/comments/6cy4pb/t470s_upgrade_satassd_to_nvme_what_about_windows/ 

>There are 2 kinds of mSATA: M.2 and NVME
You are confusing the interfaces with the form factors, mSATA and M.2 are both form factors, NVMe is an interface. mSATA only supports SATA interface, M.2 supports NVMe and SATA depending what slots / wiring it has behind it. I would be surprised if it had both mSATA and M.2 sockets, manufacturers don't normally support old (mSATA) and new (M.2) devices.

Yes, it would only offer one style of drive and the above machine has the fast (NVM-e) drive in it.

Nonsense, it only offers one form factor, the above machine takes SATA or NVMe M.2 SSDs.

https://www3.lenovo.com/gb/en/laptops/thinkpad/t-series/ThinkPad-T470s/p/22TP2TT470S lists

    128 GB M.2 SATA 3 SSD
    180 GB M.2 SATA 3 OPAL 2 SSD
    256 GB M.2 PCIe NVMe OPAL 2 SSD
    512 GB M.2 PCIe NVMe OPAL 2 SSD
    1TB M.2 PCIe NVMe OPAL 2 SSD

Two of those are SATA, not NVMe.

I was not assuming a very tiny drive. The 256 GB and above are NVM-e and that is what I was thinking above.

Please spell NVMe properly, there is no hyphen in it.
