P15 gen1 ... will a 1TB + 4TB NVMe SSD pairing work?

#1 Post by portsample » Thu Nov 27, 2025 8:23 pm

Can I have two dissimilar M.2 NVMe SSDs in my generation 1 P15 Thinkpad? Currently I have a 1TB drive and would like to add a second 4TB drive. Thanks in advance.

Yes unless you are trying to do a raid setup which in that case you'll need the same ssd for both.

Thanks. Appears there may have been space problems w/modules that had chips on both sides. I've confirmed that the Crucial 310 is single sided in this respect.
