Asus USB3.0 i SATA 6Gb/s podrškom
 
Šteta šta nema 1366 podrške... još kad bi znali kad će to biti dostupno.. šta nam sve priređuju :goood:

Kak misliš "nema 1366 podrške"? To je do proizvođača koje modele želi izbaciti s podrškom za USB 3.0 i SATA 6GB/s... Npr. Gigabyte je napravio refresh svog 1366 modela EX58 Extreme pod nazivom Extreme2 koji donosi dotične điđe. A vrlo vjerojatno će i ostali vendori prakticirati slično u budućnosti.

Taj Marvelov kontroler i nije prosao predobro na toj ploci.

Cini mi se da su privremeno odustali od njegove implementacije zbog problema u radu ...

BTW ionako ne znam kome moze koristiti ovaj nacin spajanja s obzirom na "ponudu" 7,200 RPM - 6 Gbit/s diskova na trzistu (pa cak i SSD-a), kako u HR tako i vani.

Marvelov kontroler je ipak poboljsan novim softverom, kao i mogucnoscu RAID 0... Ali sve je to nista jer su to 3rd party rjesenja koja ne donose neka poboljsanja... Malo sam pratio XS za to i vidim da nitko nije odusevljen tim marvelovim kontrolerom

@dh41400: Iako su SATA II diskovi, SSD-ovi, odredena poboljsanja su vidljiva, pogotovo kod burst testa...

Problem sa Marvelovim kontrolerom je malo dublji od problema sa softverom :) ukratko:

"The first problem is that the only SATA 6 Gbit controller available, the Marvell 88SE9123, only connects with one PCI-Express link. At best then, you get 500 MB/s, which is less than the theoretical speeds of SATA 6 Gbit/s, without counting the fact that this bandwidth will have to be shared between the two ports supported by the chip. At worst then, you’ll have 250 MB/s per port!

The second problem is that the additional PCI-Express lanes on the Intel chipsets don’t work at 5 GT/s but at 2.5 GT/s, even on the latest P55 Express. A simple design linking the Marvell 88SE9123 to the P55 Express will therefore limit it to 250 MB/s, which is less than the bandwidth you get with SATA 3 Gbit/s! Thankfully, following the “bug” of the 88SE9123 and PATA, many manufacturers have temporarily put it to one side, which spares us seeing a whole load of motherboards appearing that use this ridiculous design."


BTW burst rezultati nemaju previse utjecaja na realne performanse, nazalost.
