Hi,

 

I've had some problems with the HD since I got it, but since I've upgraded the firmware and upped the PCH voltage to 1,15 v the disc seems stable.

 

But i still got one problem:

The disc is listed with 550mb/s read and 510mb/s write.

 

Do any of you have a tip to how i can get the disc running to its full potential?

Hi guys, thanks for the quick reply.

 

I ran the ATTO test, and like you said. I ended up with a far better testscore.

 

Write 250mb/s, and read 390mb/s, (this was with the default setup in ATTO).

 

But its still not 550/510mb/s any other tweaks I should consider?

 

Im using the SATA 6/gb port

you sure you're using the native Intel 6Gb/s SATA ports?

 

Your results point me in the direction that you're not; rather the ports provided by the Marvell controller, which are BAD compared to the Intel ones.

 

The ports are color coded. Check your motherboard manual and switch the disk to the Intel ports if you can.

I'll switch to the gray one, but do I need to wipe the disc?

 

Afaik there is no need to wipe the disc. To make sure you won't lost any valuable data, if wiping is necessary, make a backup copy of it and store it on a conventional HDD.

 

After switching to Intel port, you may want to install Intel RST driver. If so, you should disable LPM in the registry for the port you connected the SSD to.

 

P.S: Glad we could help you!
