   Dear Pizzathehut,

Thank you for choosing ASRock.

The Z370 Taichi has total 8
SATA ports. If none of the M.2 slots is in used, the all 8 SATA ports can be
used.

[M2_1], [SATA3_0 and SATA3_1]
share lanes. If connect a M.2 device to M2_1, the SATA3_0 and SATA3_1 will be
disabled.

[M2_2], [SATA3_4 and SATA3_5]
share lanes. If connect a M.2 device to M2_2, the SATA3_4 and SATA3_5 will be
disabled.

Yours truly,

ASRock TSD

	No M.2 devices means you can utilize all the SATA ports.

	I'm putting together a new system and plan to have 5 storage devices and 2 DVD/Blu-Ray devices which all use SATA for their connection. There will be NO M.2 devices. The simple question is: can this motherboard support a configuration consisting 7 total SATA devices? The specs for the board state there are 8 total SATA ports. However, reading the manual I came across the following language: "* M2_1, SATA3_0 and SATA3_1 share lanes. If either one of them is in use, the others will be disabled. * 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." This wording is ambiguous and can be interpreted two ways. Which of the following is the correct interpretation? 1. Using M2 slots 1 or 2 will disable SATA port 0/1 or 4/5 respectively 2. Populating any one of M2 slot 1, SATA 3 slot 0, or SATA3 slot 1 disables the other two ports.
