    Sharing a single MB SATA Connector between two Hard Drives?


    Is it possible?

    Other than an add in PCI Card, is there any adapter that allows this?

    Sort of like the old Master / Slave IDE Cables?

    Your feedback is appreciated.

    Mike, they do the splitter cables but not sure what other bits you may need ...

    Thank you for researching and replying!

    Both of my Motherboards SATA Connectors are in use.
    One for the Hard Drive and one for the DVD Drive.
    There are no PCI expansion Slots.

    I was hoping for some solution that would allow me to Daisy Chain or Connect two SATA Disk Drives off of one Motherboard SATA Connector.
    This would allow me to have an additional Hard Drive.

    My Dell XPS 17 laptop has a jack Plug for headphones/speakers Etc, An SD card reader as Bespoke connectors and Four full function USB-C sockets /ports for everything else

    My desktop is currently offline waiting for me to find time to rebuild it so I am running the laptop as a desktop This involves a number of external adaptors daisy-chained into others to run several external drives, up to two external 4K monitors, Ethernet network and is running well, OK this is not a cheap laptop but it shows that the technology is keeping up with current user needs

    what is the motherboard ?

    I dont know a way to split a sata port to two disks.

    are you sure there are only 2 sata ports ?

    otherwise a pcie adapter or an adapter from m2 a/e wifi port

    Found an Example that is somewhat like what I'm searching for:

    Dual+docking+station+with+cloning

    It is a Docking Station with two External Mounts for Internal Disk Drives.

    Somehow it can differentiate between the two Disk Drive, allowing the O/S to assign them different Drive Letters, on ONE USB Cable.

    I does what I want HOWEVER, I'm looking for a Cable WITHOUT all the Hardware!

    I need just an intelligent Cable, one end attaching to the MB and two Sata Connectors at the other end.

    This Device, the Drive Duplicator, does what I want but it has ALL the mounting Hardware I do not need.

    I will use a 2.5 inch mounting device with two SATA Hard Drives mounted in it and just attach the Cable to them.

    If anyone knows of such a Cable, please let me know!

    All modern Drives have a unique device ID and although the basic windows software could not specifically decode the ID on the drive to provide all the data encoded there It knows enough to know that there are multiple drives in a system and allocate them different Drive letters inside Windows so you would simply select the drive you want to save to as with any other drive in a multi Drive system

    Thank you but that is not what I was looking for!

    If a manufacture can identify two unique drives in the end of a single USB Cable why cannot it be done from a single SATA Adapter on a MotherBoard?

    Because the SATA standard was NOT designed for more than one drive per port. There is no workaround that I know of.

    Other possible solutions:
    • Use an external USB/SATA hard drive
    • Replace your hard drive with a larger capacity one
    • Connect a hard drive where the DVD is connected now. Then use an external DVD drive.

    SIW2,

    what is the motherboard ? I have searched but have been unable to find it.

    I dont know a way to split a sata port to two disks. That's my dilemma.


    are you sure there are only 2 sata ports ? From all I have read and seen, YES!

    otherwise a pcie adapter or an adapter from m2 a/e wifi port

    I'll paste what I have found below:
