ASUS announce full P55 series SATA6G support with SATA6G expansion card

[sxs112]

As seen on P7P55D Premium, ASUS now use the same SATA6G solution to create a SATA6G expansion card.
It's a PCIE x4(Gen 1) card with Marvell 9123 and a bridge chip to give Marvell 9123 sufficient bandwidth for SATA6G.
With this expansion card, ASUS P55 series are now fully support SATA6G function.

[saaya]

they didnt honestly test with a hdd right? LOL
those slides are terrible.. according to them the marvell controller talks to the hdd/ssd via pciE gen2?

4lanes should be good enough to really make a diference though... def a nice incentive from asus
i just hope this card will be available and wont cost too much or it would defeat the purpose...

[Bodkin]

They say P55 only but know if it works with x58 :p

[geo]

meh. integrate wifi (n) and bluetooth with motherboards already

usable features please

Now let's see...
LGA1156 Lynnfield has on-die x16 2.0 PCIe for GPU and connects to the "SB"
by DMI, which is x4 PCIe 1.1 lanes. Through these 4 PCIe1.1 lanes, goes
the traffic of the Gb Eth, all SSDs/HDDs/ODDs, mice, webcam, external HDD,
other misc stuff; and on what's left over, this. Lol. DMI needs to die, fast.

by x4 PCIe all can run

[Bodkin]

by x4 PCIe all can run

Exelent, means I can keep my Rampage 2 for the forseable future (without having to invest in a Raid card I would not use)

totally agree... at LEAST make it pciE 2.0... at least...

[EnJoY]

I'll be waiting for native SATA 600mbps support, or better yet, 600mbps RAID cards and SSD's that support it.

[Bojamijams]

Add one of these cards in there and you can't run ANYTHING but it and a video card on a p55.. yeah baby!

[Frank M]

Yeah, I'm waiting for native support, too.

SSDs that support it? Will 525/340 MBps do? Unfortunately it's SAS-6Gbps

[Slovnaft]

soo where's the part where they support their claim that it will only work on ASUS boards?

oh that's right, ASUS employs marketing groups instead of engineers and develoepers!

DMI has 1 GigaByte of bandwidth in each direction (2 GigaByte agregate bandwidth). It is enough for 2 SATA 6 devices (500MB each). Mouse, webcam together rarely uses more the 2 MegaByte of bandwidth. Other disk devices (USB disk, SATA 3 e.t.c) also uses DMI but the situation when CPU reads sequential data from 3 devices simultaneously (from two SATA 6 + one SATA 3/USB disk) is hardly imaginable. In the case of copy (through CPU) from one disk to another, 2 GigaByte of agregate bandwidth is enough to copy from 2 SATA 6 disks to another 2 SATA 6 disks at full speed.

[kgk]

Mother of god, those ASUS press release slides read like something from an 8th grade science fair cardboard display.

80% MOAAAAAAAAAR

FASTER BETTER BIGGER SUPERGIGANTIC MEGA MORE!




I like their boards, but cut the Asian ADHD marketing when not in Asia.

[Dainas]

Not to mention the laughable placement of the bottleneck, sorry Asus but that lies squarely on the drives.

[Salavat23]

"[Sata 6G] fully unleashes HDD performance"

LOL! Most HDDs are perfectly fine with Sata 1.

[T2k]

They say P55 only but know if it works with x58 :p

And hopefully with any PCIe mobo...

Couldn't care less about wifi - who wants to be limited by some crappy-slow wireless link? -, even less about BT (a USB BT stick is under $20 and works just fine.)

It is a lot more useful than any lame, el cheapo wireless gimmick.

There are routers and wifi cards with 100mbps transfer (not 802.11n stuff).
Wired 1gbps router/switch are still expensive if I'm not wrong, so having a wireless LAN at the same speed as a normal wired one sounds nice in my book.

i asked around at computex, the big raid card guys all expect it to show up in early 2010 or even mid 2010 only, and they target a 300$+ price range :/

what? how can you claim dmi is fine? what kind of an engineer are you? :P

its 1GB/s in each direction = 1000MB/s, thats the theoretical max!
the theoretical max for sata3 is 600MB/s... PER CHANNEL, ie, PER DEVICE...
if you use 2 SSDs that can saturate the sata3 bus, dmi is limiting... and thats with dmi using for the ssds only and nothing else...

thats unlikely to happen for a normal oc these days, but there are people who do use that fast ssds... and its only a matter of time until ssds become mainstream and hdds and ssds saturate the 600MB/s sata3 at least in burst...

whats sata3 and usb3 all about? more bandwidth... then why would you connect them to a bottleneck bus that works ok now but will cr4p out as soon as those new interfaces are actually fully used?

and thats just bandwidth, how about latency and steadiness?
what if im using my gbit nic with a high dpi high refresh rate gaming mouse while copying from one ssd to another in the background?
id be very surprised if dmi isnt limiting at all in such a situation...

[T2k]

Wired 1gbps router/switch are still expensive if I'm not wrong,

Unfortunately you're dead wrong (a.k.a. clueless.) An 8-port gigabit switch is around $40, a router around $60.

so having a wireless LAN at the same speed as a normal wired one sounds nice in my book.

Too bad none offers such a speed as baseline, only as peak speed.

I'm not sure what are you guys talking about...


...but I have a ~1.4GB/s HPC storage piece at work I bought couple of years ago (though it's not big, under 20TB) and I know how many FC SCSI spindler needed to produce this speed all the time.
I also now what kind of controller it has...


...and now you guys are trying to tell me it supposed to be the same?

Because if you are then I think you guys are high.

[kl0012]

Ask Intel engineers what kind of engineers they are... but, I think - yes, DMI is fine.

its 1GB/s in each direction = 1000MB/s, thats the theoretical max!

if you use 2 SSDs that can saturate the sata3 bus, dmi is limiting... and thats with dmi using for the ssds only and nothing else...

600Mb/s mainstream consumer level SSD's even not on the horizon. But, probabaly, having even 4 such devices you wont fill slowdown on P55. In the real life apps the actual speed is much less then max achivable burst read speed. The write speed is another story.

thats unlikely to happen for a normal oc these days, but there are people who do use that fast ssds... and its only a matter of time until ssds become mainstream and hdds and ssds saturate the 600MB/s sata3 at least in burst...

It's only matter of time until storage devices saturate QPI & HT bandwidth.

whats sata3 and usb3 all about? more bandwidth... then why would you connect them to a bottleneck bus that works ok now but will cr4p out as soon as those new interfaces are actually fully used?

Why? I dont see DMI as bottleneck at least for two SSD SATA 6Gb/s disks which is, imho, an overkill for the mainstream computer in the near future.

and thats just bandwidth, how about latency and steadiness?
what if im using my gbit nic with a high dpi high refresh rate gaming mouse while copying from one ssd to another in the background?
id be very surprised if dmi isnt limiting at all in such a situation...

I think that DMI has low enough latency to handle high resolution mouse and you dont need DMI at all to copy from one HD to another (it is handled inside the chipset).

Yes, I know it's a big number.

+1 although wifi n was only confimerd this week or last, but I agree with bluetooth been too long and would be a great feature

[apt403]

Asus marketing telling Asus engineers to salvage a SATA III solution any way they can...

Considering it looks like they're using Office 97 era PowerPoint to create these slides, how much can you really expect?

[geo]

And hopefully with any PCIe mobo...

Integrated wifi and bluetooth have been part of notebooks for a while now, not to mention, the n standard has substantially increased speeds. I'm talking about home users here and not for servers or data centers.
