Comparing controllers for SATA III SSD's

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.
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.

  1. Following on from the above posts, further testing shows that the Microsoft Windows 7 AHCI driver (msahci) and the Windows 8 AHCI driver (storahci) have a performance virtually identical to that of the ASMedia 106x AHCI driver (asahci64).
