M.2 sharing SATA bandwidth

[xxdeadmanxx1]

• The motherboard M.2 slot #2 shares bandwidth with a SATA 6.0 Gb/s port. When the M.2 slot is populated, one SATA 6.0 Gb/s port is disabled.

What does this mean?

Your M.2 needs a sata port lane, it just uses a different way to access them, your motherboard manual should tell you but when you install a m.2 it will disable one of your sata ports to give it to the m.2 so that lane is technically occupied

if i had a 2.5 ssd, will it do the same?

That means you can only use one of them. When you occupy either one, the other one gets disabled.

 

Think of it as having one table and two chairs on opposing sides of the table, and someone saying sit in any chair you like. You can choose either one, but obviously you can't sit on both chairs at the same time.

Yes it doesn't matter if you connect SSD or HDD, but you probably have 3-5 more SATA ports on the motherboard to connect 2.5 SSD to.
