6 Gb/s SATA: Seagate’s Barracuda XT And Marvell’s SSD Controller

[cangelini]

As I run out the door for a trip to Europe, a couple of interesting, mysterious products appeared at the same time from different sources. We have a first look at Seagate's 6 Gb/s SATA hard drive and Marvell's 6 Gb/s SATA SSD controller.

Nice article, looking forward using this technology in a few years =)

we want usb 3 , sata 3 and pcie 3 by mid 2010 as mainstream features !

 

[cyberkuberiah]

32nm lynnfields of tomorrow should have 16 lanes but of pcie3 , so that x8 pcie 3.0 crossfire becomes comparable to x16 pcie 2.0 crossfire of today , as mainstream , because just to buy a quality motherboard with dual x16 2.0 means at least $70+ more in intel compared to 790fx+sb750 motherboards . pcie3 was due but got delayed , i sceptically wonder why .

I was looking for SATA 6Gb/s and USB 3.0 on my next motherboard. I hear there are some in the works for next year. I look forward to this being more common sometime in the near future.

Trips to Spain, constantly upgrading home theater setups, filling your NAS until you need an overkill solution, we get it Chris, you're filthy rich. >😛

Not sure I totally understand...does the Marvell controller support RAID? Couldn't you bandwidth test RAID0 configurations with the Intel G2 drives?

I WANT IT!!!

My next mobo MUST have:
SATA 3.0 6GB/s and USB3.0... PCIe 3.0 would be a bonus.

... it's a blast... the question is... when it will be getting on the mainstream...?

I would like to see a comparison between ASUS Maximus II Extreme (x58) and P7P55D Deluxe SATA III controllers to see if the P55 one truly has a bottleneck affecting the drive performance.

Hah, I wish! Just fortunate to be able to work with some cool people and cool hardware. First real vacation since my honeymoon almost five years ago!
Cheers from Barcelona!

yes and thank god nobody flagged your comment as negative ... i wonder what sort of elitist junta flagged me red for same demands ... and mid 2010 is full 8 months away !

 

[cyberkuberiah]

ok , i get it , people want it earlier than that ? even better , let's keep our fingers crossed !

There are PCI-E RAID controllers available now with
SAS/6G support e.g. Intel's RS2BL080 and RS2BL040:

http://www.intel.com/Products/Server/RAID-controllers/RS2BL080/RS2BL080-overview.htm
http://www.intel.com/Products/Server/RAID-controllers/RS2BL040/RS2BL040-overview.htm

The "SATA/6G" solution on the ASUS P7P55D Premium is not
truly "6G" because it has a bottleneck at PCI-E x1 Gen2
(250 MB/sec x 2 in one direction):

http://www.supremelaw.org/systems/asus/PCIe.x1.Gen2.jpg
(archived for "fair use" purposes: see source below)

= max headroom of 500 MB/second, not 600 MB/second.

Latter limitation is described in more detail here:

http://www.pcper.com/article.php?aid=769


The Intel RAID controllers above do not appear to have
that limitation. If I understand the Marvell controller
described in this article, a good test would be to wire
it to one of the Intel RAID controllers above and
"let 'er rip"

Does seem stupid to say "yeah! Cool! I want #####"...

oh well.
