Question: This might sound a dumb question, but I wanted to know if it is safe to connect a solid state driver (SSD). Has anyone SSDs on this switch?
Document: The unit is solid, built well. It allows you to have several systems inside one computer... independent of each other. I have my main system (os and data drive) on switch #1 via a sata power splitter . I have her system on switch #2 , and switch 3 thru 5 are other systems ; a test system , linux mint , ect . I leave the optical drive powered direct.
That means that the SWITCH constantly - 100% of the time supplies power to the HDDs. Also, the left and right supplied power to the Switch Box as I tested left and right individually connected.I then verified my VOM findings by using another PC power supply with NOTHING else connect to ensure NO damage would occur to the PC. With either the left or right power cable connected, the only correctly item functioning in the SWITCH box was the LED indicating the position of the 6 push button switches.
Nice solid steel construction. Easy to install and use. I have 4 OS's that I use and it's great to be able to select which on without using a boot selector.
I received the unit and installed it. As most have said, the instructions are dismally written.I powered up the PC with no hard drives connected to the Switch. I only had one of the two power leads connected. Immediately, the PC shut down due to power problem.I removed the Switch. Next morning, I used my VOM to suss out the problem. I had the cables all properly installed but it was NOT in the PC.
Great addition to my tower. Now I can boot up on selected hard drives with ease. I can even fire up a hard drive after boot up as I have one slated as storage. Fits in available CD/DVD slot perfectly. Cables are numbered on both ends too, making routing easier.Cons:  Cables are a little short so you may not be able to stack your hard drives in the order they are shown on the switch.
i purchase this device to control my 6 hdd drives but the switch number 5 its not working !i change the cables and the hard drive and the same problem !
I have 2 SSDs and 4 3GB HDDs in my computer. @ of the 3 gbs are for backup and this makes it very easy to turn them off when I don't want them on. Instead of having to shutdown, take off side panel, un-plug or plug-in HDDs, put side panel back on, and boot up. No thanks, now I just turn it on, restart PC and they're on, it's awesome.Blue LEDs if it doesn't say in description
This item is perfect for people wanting to dual-boot computers using different hard drives. I personally used this for a Hackintosh and Windows 7 machine. The ASUS P8Z68V-PRO motherboard works perfectly in this scenario. It has a total of 8 SATA ports which allows me room for 7 hard drives and a DVD-RW.I installed an SSD to run the Mac OSX Mountain Lion while a pair of Seagate Momentus XTs in RAID0 run the Windows box.
Every other color should be paired with a black wire.Yellow Wires: This color denotes +12 VoltsRed Wires:  This color denotes +5 VoltsThe two power cables that connect to the SWITCH Box have a single four pin plug that attaches to the left and another to the right side of the Box. It is a male connector that plugs into the female connector on the SWITCH Box.The source end of the power cable is actually two cables that feed the SWITCH Box.
I am happy with this item.
Answer: Yes, as I have three sets of SSD in raid 0 with three OS. The only thing is that the cables are not that long.
