Hello everyone.
I recently bought a Crucial M4 64Gb SSD that I have connected to an Asus P5B Deluxe motherboard with SATA 3 and on which I have the OS installed (W7 64).
I have been given the opportunity to get my hands on an Asus USB 3.0 + SATA 6 controller (which I imagine will make better use of the disk's speed) at a very good price and I was wondering if connecting the disk with the OS to a controller would be more or less reliable than doing it directly to the motherboard. I think there's nothing like having it directly plugged into the motherboard and that these things would be better left for data/supplemental/secondary disks but, honestly, it has tempted me and I don't know if the PCI bus will limit the speeds...
Thank you very much.
Best regards.
an asus card will have worse performance, leave the disk plugged into the motherboard

the truth is that it has tempted me and I do not know if the PCI bus will limit the speeds…
When you say PCI, do you mean PCIe or the traditional PCI of all time? if it is the second you will be limited to theoretical 133MB/s and if it is PCIe it depends on the number of lanes and the version, in PCIe 1.0/1.1 they are 250MB/s per lane (your case) and in 2.0 500MB/s, so you would need a second generation 1x or a first generation 4x (assuming that the 2x does not exist and the 1x is too short for a Sata 6.0Gb/s SDD). Your board only has a 1x and two 16x, so if you have the second PCIe 16x free you could use it for the controller.
I have connected to an Asus P5B Deluxe board with SATA 3
Your board has SATA 2 (2.0 -> 3Gb/s), which as you put it confuses a bit

Sorry yes, I always talked about gigas per second :rollani:
But incrediboy, if I put the Asus controller on an Asus motherboard I understand that a planetary conjunction of the butt-kicking kind occurs and that everything goes smoothly…
The controller is THIS THING and I would plug it into the free 16x.
Well kids. For the 10 euros it costs me I might take the risk and if necessary I will tell you in due time if everything has been ruined because of you :D.
Thank you very much.
Best regards.

It doesn't perform as a native SATA 6 controller but I know of more than one without problems with SATA 6 PCIe controllers. You will gain some rates but it's not something so important. I'm also not going to tell you not to buy it because as you rightly say, it comes out very cheap
-
In the end I'm getting frustrated… If I'm not going to gain anything in transfer, I'd rather leave it plugged into the motherboard. Besides, I don't have any USB 3.0 devices, which would be another reason to get it. I don't know, I have doubts :nono:.
I've searched but I can't find any graphs of transfer rates of SSDs connected this way. Do you know of any?

So according to what you put on your page, this controller is not compatible with your motherboard:sadgirl: -
In the end I'm getting frustrated… If I'm not going to win in transfer I'd rather leave it plugged into the board. Besides, I don't have any USB 3.0 devices which would be another reason to get it. I don't know, I have doubts :nono:.
I've searched but I can't find graphics of transfer rates of SSDs connected this way. Do you know of any?
If you reread you'll see that rates do win, what happens is that since it's not a native controller you lose a little bit of performance in general. If you get frustrated that's fine but don't give up the SSD, after all, what's important is access.

So according to your page, this controller is not compatible with your motherboard:sadgirl:Mmmmmmmm strange because if the PCIe is valid, there shouldn't be any problems, right?… Thanks for the info anyway.
Obione, I wouldn't give up the SSD in any way. It stays where it is, with or without the controller.
Best regards.

rare or not is what asus says, that it won't work or that it won't have all the speed that remains to be seen, but that's what there is.
now you buy it, test it and you'll tell us :D:D:D -
If you reread it you will see that the drives do win, the thing is that since it is not a native controller you lose a little bit of performance in general. If you overclock it's great but don't give up the SSD, after all the important thing is access.
Because it will lose performance, whether it's a native controller or not it goes through the same bus, there shouldn't be any differences. Connecting it to the 16X will give you perfect performance. Anyway it's a matter of running a test on the drive and you will quickly know if the controller is at maximum or not, if you see that the one you have in front with the SATA6 is limiting you.
-
It will be because of the controller because the one on the Lian-Li NAS performs better but the Asus one, which I think is Marvell, doesn't have the same performance as a native one, if anything, it has higher read rates.
Another reason to use the native one is TRIM.
-
It's not really about limiting myself (it goes as it should to go over a sata 3Gbps) but rather to make better use of the 6Gbps of the disk. In short…, there is no better proof than buying it and doing the relevant tests.
I'll be back :rollani:
Thanks to all.

¡Clarinete!
Also I just asked Asus and they told me why, among other things, it's not compatible and it seems that my board does not support booting from PCIe so even though it might work for any other disk, I could hardly connect the SSD with the OS to the controller :rollani:
Thanks.
Best regards.
-
Man, there must be some way to cheat that problem, with a boot loader or something, but as you can see in the comparison, you're not going to notice any differences... so I think it's not worth it for you.
-
The savings are not worth the hassle :risitas:
Thank you all very much.
-
it's not compatible, I already told you, but it seems that opinions count more than facts:nono:

Fortunately here your opinion is not going to mass, and I hope not in any other site. Even so anyone would value more what the manufacturer (Asus) says than what any forum member says (whether it's you, me or anyone else).
-

I'm sorry you felt offended :nono: and I will try to make it up to you by always accepting your word and the manufacturer's word from now on :rollani:.
On the other hand, the response I have received from Asus is that the controller is compatible and works perfectly with USB 3.0 and would work without problems with any disk as long as it is not bootable, which is the function that the board lacks, and that is why it is not on the list of compatible ones, because it does not support all the functions that the controller does provide.
Best regards.

Hola a todos.
Al final compré la tarjeta y funciona perfectamente (parece que sí era compatible :facepalm:). No he hecho pruebas aún ni he podido conectar el disco de arranque para ver si por lo menos inicia pero me pondrá a ello. A simple vista el USB 3.0 no parece mejorar mucho la velocidad con respecto al USB 2.0 pero ahí está. Intentaré hacer alguna prueba y colgar por aquí los resultados.
Un saludo.
