This thread is listed in the Elite Posts.

After researching the installation of an Intel 520 180GB SSD with a U3S6 add-in card and an Asus P6T Deluxe motherboard, I have made the following conclusions:

1.       The U3S6/Marvell 88SE9120 SATA controller passes Trim commands.

2.       The latest Marvell AHCI ( driver produces good speeds with a 6Gb/s SSD.

3.       The Marvell AHCI driver does NOT pass Trim, and according to Marvell never will.

4.       The Microsoft AHCI (6.0.6002.18005) driver on the Marvell 88SE9120 performs very poorly.

5.       A 6GB/s SSD performs better on an Intel 3Gb/s controller with the Intel RST (iaStor) driver.

6.       A 6GB/s SSD performs to its maximum only on an Intel 6Gb/s controller.

7.       Only connect a 6GB/s SSD to an Intel controller for best performance.

Update to previous post........

In order to determine the optimum method of connecting a SATA III SDD to a Vista 64-bit system with  SATA II controllers, a number of add-in SATA III controllers have been tested and compared with  the Intel SATA II and SATA III ports. The following conclusions were made:-


1.       The Marvell 88SE91xx SATA controller passes TRIM commands (in by-pass/non-RAID mode).

2.       The latest Marvell driver ( gives good overall performance with the Marvell 88SE91xx SATA controller, but does not pass TRIM commands.

3.       The ASMedia ASM1061 produces the fastest speeds of the currently available add-in 6Gb/s SATA controllers.

4.       The ASMedia ASM1061 controller passes TRIM commands.

5.       Both the ASMedia driver ( and the Microsoft AHCI driver (6.0.6002.18005) support TRIM commands with the ASMedia ASM1061 controller.

6.       The 3Gb/s Intel controller, with the Intel RST driver, gives speeds approaching those of the ASMedia ASM1061 and ASMedia driver, especially when used for a system drive.

7.       The Intel 6Gb/s SATA controller gives the best results of all.

8.       Wherever possible always connect a 6Gb/s SSD to an Intel 6G/s SATA controller.

9.       The Microsoft AHCI driver (6.0.6002.18005), standard with Vista 64-bit, performs very badly with random transfers, especially with queued transfers, and its use should be avoided. The Windows 7 version of this driver is different and may give better performance. Subsequent testing has shown that the Windows 8 AHCI driver (storahci) performs virtually identically to the ASMedia ( driver.

10.   Future add-in cards, using the new 6Gb/s Marvell 88SE92xx controller, will probably have a performance as good as the Intel PCH 6Gb/s SATA controller.

Document in above link modified to show that the Windows 7 & Windows 8 AHCI drivers give virtually the same performance as the ASMedia 106x AHCI driver (asahci64)

I have examined both the HighPoint Rocket 640L and the Syba SD-PEX40054, but have not tested either.

The 640L uses the Marvell 88SE9235, whereas the Syba uses the Marvell 88SE9230.

There are 3 versions of the Marvell 88SE92xx controller. The 88SE9220 is a 2-port version; the 88SE9230 is a 4-port version, both with hardware RAID support. The 88SE9235, is also a 4-port controller but only supports software RAID. To get the full advantage of the 2-lane PCI-e interface it is advisable to only connect a single SSD to the controller. The 2/4 ports are for use with the “HyperDuo” mode, where a small caching SSD is used with a larger HDD to give significant performance improvements over stand-alone HDD’s.

The Syba SD-PEX40054 appears to be remarkable value, when compared to the 640L. I asked Syba customer support whether the card would work with a single SSD, and whether it would work with the standard Microsoft Win7/8 AHCI drivers. Syba replied that whilst it would support a single SSD, it would not work with the Microsoft AHCI driver. Upon questioning the view that it would not work with Microsoft driver, Syba simply replied that they could not recommend it because they had not tested it.

My view is that it will work with the Microsoft driver and there are various postings which support my position, at least with the 640L - see the feedback post from GonZo here.

Whilst the adoption of a 2-lane interface for the 88SE92xx series will undoubtedly produce faster sequential speeds, the random throughput mat not be that much improved over the 1x lane 6Gb/s controllers , if at all. This report here clearly shows that the ASM1061 is in fact slightly better than the 640L with 4k sequential and random data, and also not far short of the Intel 6Gb/s controller.

On systems where the SSD is used purely for the system drive, the ASM1061 performance will be virtually indistinguishable from the 88SE92xx or the Intel Series 7 6Gb/s controller. On the basis of that I have continued to use the Syba SY-PEX40039 (ASM1061) - and I have not been disappointed. I don’t think I will bother to “upgrade” to the 88SE92xx.
