S3700 SSD SATA2 mode instead of SATA3

[idata]

Hello!

I have several Intel SSD DC 3700 Series drives.

100GB, 200GB and 400GB and all have firmware 5DV12270.

100GB and 400GB drives work fine but the 200GB SSD works only in SATA2 mode with the same ports (SATA3) and cables (SATA3) with which the 100GB and 400GB drives work as SATA3 mode.

What could be the problem?

Hi fptas1979,

I've been trying to reproduce the behavior you are describing but I'm not able to get the same result.I've sent you a private message with additional instructions about how to proceed from this point. Please check it in your inbox.Have a nice day.Regards,Diego V.

Hello!

After many tests with different motherboards, drivers, cables and so on I was very frustrated.

Then I came up with the idea to change or reinstall the drive parameters in isdct with hope that after that the drive will work as it should.

Setting PhyConfig = 0, 2, 1 gave nothing.

Then I decided to change PhySpeed.

Description:

PhySpeed- Changes the devices maximum allowed PHY Speed it is allowed to negotiate. Valid values are:

- 1.5: SATA Gen 1 speed of 1.5 Gbs

- 3: SATA Gen 2 speed of 3 Gbs

- 6: SATA Gen 3 speed of 6 Gbs

Previously for my drive I got:

PhySpeed: 6.0 Gbps

...

SataNegotiatedSpeed: 3.0 Gbs

And I thought that my drive was set to PhySpeed=6, but it only works at 3 Gbs.

I ran the "isdct set -intelssd PhySpeed = 1.5" and rebooted the computer.

The "isdct show" showed me this:

PhySpeed: 6.0 Gbps

...

SataNegotiatedSpeed: 1.5 Gbs

Then my heart pounded, because I realized what it could mean.

I ran the "isdct set -intelssd PhySpeed = 6" and rebooted the computer.

The "isdct show" showed me this:

PhySpeed: 6.0 Gbps

...

SataNegotiatedSpeed: 6.0 Gbs

Other test programs also showed that the drive is running in SATA3 mode and the transfer rate was consistent with this!

So, I realized that the value of PhySpeed in the output of the "isdct show" most likely shows the constant value of the fastest protocol revision, on which the drive can work (SATA1, SATA2, SATA3), not the current set value of this parameter.
