" rel="nofollow - I recently saw the newly released Asrock B450 pro4 ATX mobo & checked its official specifications on asrock website. To my surprise I noticed that under storage specifications it says "*M2_2, SATA3_3 and SATA3_4 share lanes. If either one of them is in use, the others will be disabled." which basically means one can not use sata 3_3 & sata 3_4 simultaneously even if no m2 ssd is installed in M2_2 slot.Is this correct because this is the first time I am seeing sata ports sharing bandwidth with each other in such a way that using one of them disables the other? Even the previous AB350 pro4 official specs only mention that one sata port will be disabled if a m2 ssd is installed in M2_2 slot.
