Special m.2 SSD Slot

So I bought a new Thinkpad P16S AMD for college it came with a 512GB NVMe.

I decided to upgrade the NVMe to a 2TB Kingston KC3000 but when I attempted to install the drive it wouldn’t fit.

The interface is not the problem,

The m.2 drive that came with the laptop I noticed had no memory chips on the underside of the SSD and the height of the slot was smaller than a regular slot like the one in my Desktop Motherboard

Is there some new m.2 standard for skinny drives, when I go searching for another 2TB NVMe how do I ensure I get a drive with no chips on the underside?

By skinny, you’re referring to components only on one side?

If so, the M.2 sizing spec (ie: 2280) will sometimes have ss or ds appended to indicate that it’s a single side or double side chip.

Yes components only on one side, the controller and memory chip was on the top side the underneath was just circuit board

It’s possible that among double-sided M.2s, some will work and some will not, and with the difference determined by mere fractions of a millimeter height on the bottom side.

Which means It’s probably not worth the hassle to go through measurements or trial and error. :sweat_smile:

For what it’s worth, the last few Crucial P5 Plus M.2 2TB drives I’ve bought for work and home have been single-sided, so those are a decent option to be sure :slight_smile:
