@Fernando,
Thanks for the 64 bit variant of V1.2.0.1040. I'll do a test soon.

Here is attached a CDM4 benchmark result for both Intel and Marvell to compare the performances using the same hardware (PC and SSD).
Figures are quite 'speaking'.


Another test I have done is trying to install Marvell v1.2.0.1036.
Unfortunately, a warning message occurs during the installation procedure such as: ".. not able to verify the compatibility with your system.." ".. instability may occurs.."
So, finally i did not installed it and I classify this .1036 as a not recommended and 'risky' driver.

@Fernando
Here is the reply for v1.2.0.1040: TRIM is NOT working for sure. (many tests done).
Here are some tests results: Properties, CDM4, DriverInfo, TRIMcheck.






So, for me the more "recent" release with TRIM supported is v1.2.0.1035.

Conclusion (for me):
Seems this TRIM functionality worked (and works) fine up to v1.2.0.1035 (included)... and then disappeared for any obscure reason that only Marvell knows.

I guess these are...

@Fernando

I tested both new Marvell drivers: Marvell MV-91xx/92xx SATA 6G Controller version 1.2.0.1046 WHQL and Marvell MV-91xx/92xx SATA 6G Controller version 1.2.0.1047 WHQL.

I did it on my Asus P8P67 Rev3.1 which has an onboard SATA controller Marvell 88SE9120 with an updated Marvell AHCI-ROM and BIOS version 1.0.0.0034 and with a 256 GB SSD Samsung 830.
Unfortunately both drivers do not support TRIM.

Besides the Marvell MV-91xx/92xx SATA 6G Controller version 1.2.0.1047 is not WHQL. The setup software did not work too. So I had to do the installation manually with the device manager.

I also did a control test with the older Marvell 91xx/92xx SATA3 drivers version 1.2.0.1035 and there is TRIM support.

@Fernando

In my Windows 7 device manager the driver Marvell MV-91xx/92xx SATA 6G Controller version 1.2.0.1047 is not digitally signed.

@Fernando

I tested the second new Marvell MV-91xx/92xx SATA 6G Controller version 1.2.0.1047 WHQL (2).

I did it again on my Asus P8P67 Rev3.1 which has an onboard SATA controller Marvell 88SE9120 with an updated Marvell AHCI-ROM and BIOS version 1.0.0.0034 and with a 256 GB SSD Samsung 830.
Unfortunately and as expected the new driver does not support TRIM.

Besides the second new Marvell MV-91xx/92xx SATA 6G Controller version 1.2.0.1047 WHQL (2) is really WHQL now. There is also no error message after the manual installation with the device manager anymore.

I also did again a control test with the older Marvell 91xx/92xx SATA3 drivers version 1.2.0.1035 and there is TRIM support.

The AMD AHCI drivers for Windows XP provided by Asus seem to work fine, but they do NOT make the S.M.A.R.T. information available. Do the drivers available for download on this website do so?
