Merci ontarion ! Un test fort intéressant que j'avais déjà eu l'occasion de lire !
On peut voir sur ce test, que le Marvell 6 Gb/s est un tout petit peu au-dessus du Intel 3 Gb/s, sauf en aléatoire.
Sinon je ne maîtrise pas bien la langue de Shakespear, mais je suis tombé là-dessus concernant les différents contrôleurs (Intel, Marvell, ASMedia) et ça à l'air assez intéressant. En cliquant sur un des liens on tombe aussi là-dessus, traduit du japonais. Par contre je ne sais pas interprêter les tableaux de CrystalDiskMark 3.0.1b... Mais j'ai l'impression que le SSD Caching (HyperDuo) sur le contrôleur Marvell à l'air de bien fonctionner.
Du coup j'hésite à nouveau avec une nouvelle variante :
- Sur le Intel 6.0 Gb/s : SSD 256 GB + HDD DOCK
- Sur le Marvell 6.0 Gb/s : rien
- Sur le Intel 3.0 Gb/s : Blu-ray + SSD 128 GB + HDD 2000 GB >>> SSD Caching
Ce que je me pose comme question avec ce SSD Caching, c'est si le SSD rend l'âme, est-ce qu'il y a une incidence sur le HDD ?
Du style on arrive plus lire le HDD comme quand un disque lache en RAID0 où je ne sais quoi... Mais comme c'est une question de mémoire cache, ça ne devrait rien faire ?
Et sinon, vous qui connaissez CrystalDiskMark, que disent vraiment les résultats obtenus ? Je ne sais pas les interprêter !
Je vous remercie encore pour votre aide !
Et désolé si la discussion navigue entre carte mère et SSD ! J'hésitais entre les 2 alors si il faut déplacer, pas de souci !
EDIT1 : Correction en-dessus
EDIT2 : Je mets juste la conclusion d'un des liens en-dessus, pour ceux qui ne voudraient pas tout lire.

Observations & Discussion
The 6Gb/s Marvell and ASMedia controllers, used with the standard Microsoft driver, producesequential read and write speeds virtually the same as when using the Marvell and ASMediaproprietary drivers. For smaller random transfers the Microsoft driver gives very inferior data rates,especially at the larger queue depths. The access times are also significantly worse with theMicrosoft driver. It would appear that the Vista (64-bit) in-box Microsoft AHCI driver is notoptimised for NCQ or small block transfers - at least with these controllers. This may be acharacteristic of the Vista driver, because the Windows 7 standard Microsoft AHCI driver is widelyreported to work well with SSD's.
Overall, the ASMedia controller is faster than the Marvell controller, and in particular has a betterbalance between read and write speeds. A major advantage of the ASMedia device is that both thecontroller and driver passTRIM. The Marvell only passesTRIMwith the Microsoft driver, but withvery poor transfer speeds. The ASMedia controller with the ASMedia driver is currently the best add-in controller.
The Intel ICH10R 3Gb/s controller, with the Intel RST driver, produces overall speeds slightly lowerthan those obtained from the 6Gb/s ASMedia/ASMedia controller and driver combination. TheRandom transfers are virtually the same, the queued random transfers are lower, but with similaraccess times. Naturally, the Intel controller has worse sequential speeds due to it being a 3Gb/sSATA device rather than a 6Gb/s type. The 6Gb/s ASMedia controller and driver combination isbetter on virtually every score than the 3Gb/s Intel/Intel setup.
If an Intel 6Gb/s SATA port is not available, and since it is important to use an arrangement that fullysupportsTRIM,the best controller is the ASMedia/ASMedia combination. However, the 3Gb/sIntel/Intel RST combination is better than the Marvell/Microsoft set-up, especially for system drives,where most data transfers will be highly random. Sequential transfer speed is less important forsystem drives.
The Intel 6Gb/s controller with the Intel RST driver gives the best results of all, although as a systemdrive its speed benefits with random transfers may not be very noticeable in practice. As a data drivethe higher sequential speeds would be beneficial with large file transfers.
If the ultimate performance with an add-in controller is required it would be wise to look out for anew 6Gb/s expansion card, using the Marvell 88SE92xx controller, becoming available.
There has been much discussion about whether the Marvell 88SE91xx supportsTRIM.Results fromusing the Intel SSD Toolbox results clearly show that although the controller does passTRIM, thelatest Marvell driver (version 1.2.0.1019) does not passTRIM.It has been reported (see here and here)that Marvell claim the driver was developed for OS's which do not have ACHI drivers (i.e. pre-Vista systems), and recommend that the Microsoft AHCI driver is used with Vista and Windows 7. Itis also reported that the Marvell driver will never passTRIMbecause these legacy OS's, for which itwas written, do not generate the necessaryTRIMcommands.

It has not been determined whether the Intel RST driver is better than the Microsoft AHCI driver onthe Intel SATA controllers, but many users report that the Intel RST is marginally better.
Although the tests were made with a 64-bit Vista system all results, with the possible exception of those for the Microsoft AHCI driver, will carry over and be true for Windows 7 & 8 based systems.
Conclusions
1. The Marvell 88SE91xx SATA controller passesTRIMcommands (in by-pass/non-RAID mode).
2. The latest Marvell driver (1.2.0.1019) gives good overall performance with the Marvell 88SE91xxSATA controller, but does not passTRIMcommands.
3. The ASMedia ASM1061 produces the fastest speeds of the currently available add-in 6Gb/s SATAcontrollers.
4. The ASMedia ASM1061 controller passesTRIMcommands.
5. Both the ASMedia driver (1.3.4.0) and the Microsoft AHCI driver (6.0.6002.18005) supportTRIM commands with the ASMedia ASM1061 controller.
6. The 3Gb/s Intel controller, with the Intel RST driver, gives speeds approaching those of theASMedia ASM1061 and ASMedia driver, especially when used for a system drive.
7. The Intel 6Gb/s SATA controller gives the best results of all, but as a system drive it may notshow a large improvement over the ASMedia/ASMedia controller/driver configuration.
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 withrandom transfers, especially with queued transfers, and its use should be avoided.Subsequent testing has shown that the Windows 7 AHCI (msahci) and the Windows 8 AHCI driver (storahci)both perform almost identically to the ASMedia (1.3.4.0) driver.
10. Future add-in cards, using the new 6Gb/s Marvell 88SE92xx controller, will probably have aperformance as good as the Intel PCH 6Gb/s SATA controller.
