DH61WW SATA type to SSD SATA III 6.0

Good night

I would to know if my old DH61WW motherboard has any SATA III 6.0 to connect a brand new SSD SATA III Western Digital Green. 
If not, can I connect it and it will work at SATA II speed?
Any review about it?

Thank you

6 Series boards only had support for SATA II built into their chipset. While some boards provided a secondary controller chip with SATA III support, your board did not.

In a SATA II port, a SATA III device will operate at SATA II speeds (i.e. 3.0Gb/s instead of 6.0Gb/s).

Replacement SATA III controllers are available and fairly cheap. Here is some examples: 

  1. Two Port (US$13): https://www.amazon.com/dp/B07N3B258F
  2. Four port (US$25): https://www.amazon.com/dp/B00AZ9T3OU

Hope this helps,

Thank you!!

You solved it.
First, I can use the SSD at SATA II speed, and after I buy the PCIe.

Does the PCIe bus speed support the SATA III speed? 

Thank you

The PCIe lane in your board's PCIe 2.0 x1 add-in card connector has a transfer rate of 5GT/s, which means that it can transfer up to 500MB/s. Each SATA III port has a transfer rate of 5Gb/s, which means that it can  transfer up to 600MB/s. This means that a single SATA III port can potentially saturate the PCIe lane. Now, typical operations do not come close to this 600MB/s limit, but you can see that supporting more than two SATA III devices is going to be problematic. I thus suggest that you limit yourself to a 2-port card; you can rely on the SATA II lanes in the chipset to support your slower ODD(s) and less-seldom-accessed HDD(s).

I have never used an add-in card that supports more than two SATA III ports. The card that I have typically used to soup up older (5 and 6 series) systems is a little pricier. You can see it here: https://www.amazon.com/gp/product/B01452SP1O. This card physically hosts the SATA III SSD, avoiding the need for a cabled mount point elsewhere in the system, as well as providing a second SATA III port for a Data HDD or even SSHD.

Hope this helps,
