Subject: How to use m.2 ssd and all sata ssd on A3

Dear Checknix,

Greetings, this is ASRock TSD.

This board supports two M.2 Socket:

- 1 x Ultra M.2 Socket (M2_1), supports M Key type 2242/2260/2280 M.2 PCI Express module up to Gen3 x4 (32 Gb/s) (with Summit Ridge, Raven Ridge and Pinnacle Ridge) or Gen3 x2 (16 Gb/s) (with A-Series APU)

- 1 x M.2 Socket (M2_2), supports M Key type 2230/2242/2260/2280 M.2 SATA3 6.0 Gb/s module

*M2_2 and SATA3_3 share lanes. If either one of them is in use, the other one will be disabled.

Detailed specification:

For your M.2 SSD, please install it to M.2_1 slot and then all of the SATA ports can be used.

Thanks!

All the best,

ASRock TSD
