The SW-SATA2X4 4 Port SATA III Switch is Bay Mount designed to provide a high performance link between a single SATA 2/3 host port and 4 SATA device ports. It connects the host upstream port to one of the 4 downstream SATA devices (one device at the same time). It is done by simply pressing the push button switch.

With its Power Switching circuits, the SW-SATA2X4 can switch the devices power according to the settings of the SATA II / III signal switch once bay mounted. The 4 Port SATA Switch only allows the selected device to be powered and cuts off the powers of the other un-selected devices. This reduces the power consumption and makes sure those devices are truly off line to prevent from any accidental erasing of data by virus or application software.


The SW-SATA2X4 4 Port SATA switch provides a key lock mechanism to prevent from any unauthorized changing in drive or device settings. It helps home and school users to manage the devices quickly and easily.

11 reviews for 4 Port SATA II / III Switch 3.5inch Design With KeyLock and LED

  1. Si Sancho

    The concept is great, the implementation is good but a huge disappointment when the first installation indicated that Ports (drives) 3 & 4 were DOA! Hopefully the replacement will work better. I agree with some assessments, such as the drive selection process, one switch per drive would be better than racing the 10 second boot process to punch the button 5 times to get to drive 4! The key seems redundant! Overall I am pleased despite the failed product. If the replacement fails then logic 1 goes to 0!

  2. Napoleon

    Please put the LED lights farther apart. Please allow the user to choose the HD before pressing the ON/OFF button on the computer. Four buttons instead of one so we can press a button once instead of up to 4 times would be very good. I love the product. I bet many households avoids buying a second computer because they bought the switch. I bought 3 switches and like 2 years later they all work.

  3. SDH

    I agree with other reviewers…. the manual needs to be redone. You cannot even see the pictures clearly enough to figure out what the intent is. So, here is how to hook up the cables, and the description is valid if you set the device down and look at it from the rear. If you do this then (1) to the far left is the power-out connectors for up to 4 drives. For those 4 the first set of two (against the far left edge) are for drive 2 against the rear edge, and then drive 1 in front of 2, towards the front. The next set of two is for drive 4 and 3, with the drive 4 connector being against the rear edge. Next, to the right, comes (2) a stacked set of two SATA data male connectors with the port for drive 1 on top and that for drive 2 beneath. Then, to the right of those, comes (3) a single male SATA data port for a single SATA cable to interface between the device and your motherboard. Then, to the right of that comes (4) another stacked set of two SATA data male connectors with the port for drive 3 on top, and that for drive 4 beneath. Finally, to the far right comes a single connector for power to come in from the workstation to feed the device and whichever ever single drive you have selected to be active.

    If you want to have multiple isolated Hard Drives on your Computer this is what you need. You can have up to four drives and can select at boot which one you want to use. The others will remain powered off. This allows for multiple Operating Systems on your computer without any possibility of virus/malware “crossover” as can happen on dual boot systems. I gave four stars instead of 5 in “Quality” only because the instructions are unclear but it’s not hard to figure out how to use this…

  5. James Holm

    A much better idea than setting up several operating systems on a mult-boot drive.
    Important during this time of Windows XP, 7, 8, and now 9 Beta.
