SATA 6gb/s backward compatibility

[samadchaz]

Is it possible to install a SATA 6gb/s HDD in an old motherboard of SATA 3gb/s by using jumpers :confused:

I am going for WD Caviar Black FAEX and have G41 chipset

My HDD is 6Gb/s, but my mobo only supports speeds up to 3Gb/s. Works for me.

From what I've read they should be backward compatible -- they use the same connectors and will just run at the speed of the connection they are plugged into - so when using a 6Gb\s HDD in a 3Gb\s MOBO you'll just get up to the 3Gb\s speed but it should work fine.

 

I had looked through several articles to figure out the same since I was replacing a dead HDD but wound up getting a 3Gb\s Samsung 1TB HDD for $49 shipped instead of the WD Caviar Black since it was about half the price and fast enough for this old system !

I Highly recommend replacing any HDD with this awesome hd.

Your BIOS might have settings for HD speeds. I'm using a 6 Ggb/s and a 3gb/s and an old IDE. All 3 run as they should.

thanks for the replies :biggrin:

and thanks for the link Thor but I dont buy online, we have Dealers. and I will buy a separate SSD for OS.

Just ask the shop keep for a momentus HD, they'll probably be able to ship one in for you :thumbsup:

 

And same with the dealer thing, Especially when you have a Tigerdirect near by :thumbsup:

ah I see, I ask them about momentus, but its more costly than a SSD :wacko: (of course I ask them again about OCZ vertex 3 but I wont tell anything here :ninja:

 

Now I have the WD FAEX and its actually have the jumper settings saying that 3gb/s for 6 and 7 pin, and I didnt even install it yet just because of that(wrong jumper setting). Please help :sad:

On WDC, jumpering pins 5 & 6 (i think not 6 & 7) cause the HDDs will be SATA II,(PHY or phsical layer 3 gb/s will be enable), another jumpered pins are 1 & 2 to enable SSC, and 3 & 4 to enable PUIS..

I have SATA III(seagate) on my P45 w/o any problems, but i didnt see any improvement of speed by using SATA III, since P45 doesnt support SATA III...

here is detail for installing jumper on WDC HDDs.
