SSD on ICH7 controller

SSD on ICH7 controller

So it the Host Adapter (Controller) on the MoBo that causes the limitation?

I can speak for notebooks and desktop use but the speed limitation is definitely evident on my netbook. I am not sure whether it a BIOS or Host Adapter issue in my case but I guess the BIOS, Host Adapter (on MoBo) and Host Controller (on SSD) all work hand in hand.

PS: I personally believe the limitation issue would be fault of the Host Adapter on the Mobo or the BIOS. It wouldn make sense for the issue to be the SSD.

So, because some claim that the ICH7 limitation is 80MB/sec,

those Intel SSDs are not a good buy, they will be limited by laptop controller.

Also, Vertex might have same problems and Samsung too.

Is that true? Have anyone tried them on similar laptop?

What interestes me is to invest to a SSD with a good controller (not JMicron), but with

the read/write up to the speed the laptop can take, so as to spend less money.

You will be fine. I ran a MLC SSD on my asus and it has a 945G chipset. Average speeds were over 100mb/s peak at just over 120mb/s as the drive specs stated.

I agree with your idea, no need in spending more for a item faster than your laptop can handle. However also keep this in mind

SSD are supposed to last a long time 5 years for MLC and much longer for SLC, im sure you wont keep your current laptop for more than 3 years or so, so if you get a faster one now you can just install it into your next laptop.

Of course by that time SSD will be much cheaper faster so you may just want a new one anyways.

and, the main thing about ssds is their latency. i have a samsung with 100MB/s readwrite, and one with 200MB/s readwrite. they behave the same as they have the same latency. max troughput doesn really matter much.

the mtron, while only having 80MB/s in my elder notebook, had lower latency and performed more snappy and much faster than the samsungs. maybe an slc/mlc thing, too.

but besides the possibility of stutterings that may appear if one throttles an ssd, the fastest ones (intel ones) would still perform fastests even when max speed is capped.
