I have an HP EliteBook 840 G8.  Can anyone help with M.2 SSD compatibility Please? I wish to upgrade to a WD SN850X 2TB Gen 4 SSD.

 

My question is: Will the version with HEATSINK fit or do I need the NON HEATSINK version? Also, If anyone has suggestions about other M.2 SSD's that may be better, please advise me. 

 

Many thanks,

Michael

@KAR120C,

 

The service manual (on page 2) shows supported storage drives that include a 2TB M.2 NVME gen 3x4 SSD.

Maintenance and Service Guide

 

A WD M.2 NVMe SSD you linked should work but will run at around gen3 speeds, as your M.2 slot is PCIe 3.0 (gen3).

 

Pages 41-42 of the manual show a thermal cover is preinstalled on the M.2 NVMe SSD, so you have to buy an M.2 SSD without a heat sink.
