I have a somewhat strange question, and I am looking to see if anyone can shed some light...
I have a Kingston HyperX SATA3 (6Gb/s) 120GB Sandforce based SSD coupled with my Sabertooth 990FX which is absolutely amazing. However, I have found out that when I plug a large format spinny drive into one of my available SATA3 ports (I have 6 total) my system is a lot more sluggish.
It is about a 10sec difference on boot, just by plugging the HDD in, even if the drive is blank, and I ran Crystal on it, which gave it about 380MB/s read, and 74-120MB/s Write, which is a lot slower than the 555/520 that I should be getting.
Is the slower interface of the HDD's causing the bus to slow down to that speed?
If I use the JMicron SATA2 controller for the HDD will I still see the performance drop?
If I put my SATA DVD drive on the SATA6 bus will it cause it to slow down further?
Are there settings I should have set up to keep this from happening?
Any ideas / thoughts / experience that any of you have had?
I'm not to familiar with your board but, I know there are limitations on just how fast the combined sata III ports will go (on all boards). For instance with my board (Asus Rampage III Formula) the newer/faster sata III SSD's can have a hard time reaching their top speed due to the controllers one PCI lane limitation. If yours are limited to the total speed of what your SSD can produce, that could be a factor.
That's exactly what doesn't make sense. I've been on and off the phone with the Kingston engineers a couple times now. seems like they can't duplicate the problem, which points towards my board. Since they are using the same hardware as me.
Well look, I didn't come here to argue only to help. The possible solution I pointed out has nothing to do with Kingston and everything to do with your board. And to be fair I don't know if it will work, only that it looks to me like it might.
I also have the Kingston ssd and the asus sabertooth 990fx and it is the slowest of all pcs to boot in my house. It is very frustrating and led me to purchase a different and cheaper mobo for my other amd setup.
My family all plays WOW and this pc has the slowest load times, but has'better' hardware. I am going to use the suggestion of raid 5 and see if that does anything for me. This pc also is the least used and has the least amount of programs on it. I understand there are faster ssd's on the market, but I think it is the board.
