Which M.2 slot for NVME boot

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I am getting ready to build new system on my z370 Taichi.  I have a Samsung 1TB 970 Evo M.2 that I want to use as my boot drive.  Is one of the three M.2 slots preferred for this purpose?
I will eventually be adding additional SATA 3 SSD's, but not initially.

	Dear EMurrow, The Z370 Taichi has three M.2 slots supports SATA3 6.0 Gb/s module and M.2 PCI Express module up to Gen3 x4 (32 Gb/s). M2_1, SATA3_0, and SATA3_1 share lanes. M2_2, SATA3_4, and SATA3_5 share lanes. If either one of them is in use; the others will be disabled. If M2_3 is occupied by a SATA-type M.2 device, SATA3_3 will be disabled. https://www.asrock.com/MB/Intel/Z370%20Taichi/index.asp#Specification For your case, we suggest connecting the 970 EVO at M2_3 slots, then all the SATA ports can be used. Yours truly, ASRock TSD
