Pci-e 3.0, usb3, sata3

[kalniel]

Anyone know when these are expected?

I guess SATA3 is the nearest, with controllers out there already. USB3 is probably next, but I'm not sure of any dates, and PCI-E 3.0 the last.. but when?

Worth holding out on a new system until motherboards come with them?

[GheeTsar]

My thoughts exactly - do I hold off on a new motherboard/CPU until these are standard? I'm tending towards "yes" at the moment.

Not positive about the other two, your guess seems correct.

PCI express 3.0 will be sometime mid 2010, considering not many cards max out 16 pci express 2.0 lanes, it won't be needed really

im tending towards no, since my mobo cant run pc with out crashing when i quit a game and my point went for DDR3 i still question the value off that atm

And I've just had the realisation that decent Lynnfield chips won't ever have PCI-E 3.0 so I can probably scratch waiting for that one.

Lots of conflicting dates but these seem to be the ones that keep popping up;

PCI-E 3.0 - Q2 2010

SATA 6 Gb/s - no idea on a date, but there are boards out there which have the controllers/ports already.

USB 3.0 - Q1 2010

can someone explain to me the point of waiting for sata 6Gb/s if your only running normal hard drives?

i understand if you are planing to have SSDs but why with normal hard drives?

[TooNice]

I'd say none if not for SSD, unless you strip two or more drives.
I am also wondering when we'll see Certified Wireless USB 1.1. Version 1.0 wasn't too impressive by most account, but it would really save me some cable tangle if they improve on it and they can make 2.5" HD and pen drives that supports it.

[mycarsavw]

There is no point for "normal" HDDs.

One of the articles in my post above suggests conventional HDDs are not even close to saturating first gen SATA speeds.

At the moment there's no point, but I tend to keep systems for a rather long time (by enthusiast standards) and hard drive speeds are increasing at a faster rate than they've ever done before so I can say with some certainty that they'll be exceeding sata 2 speeds well before the end of life of my next system. (We're exceeding Sata 1 now, and my current motherboard only shoe-horned in one Sata 2 port via an extra chipset it was that new at the time).

[TooNice]

I don't think any single mechanical drive exceed SATA-1 bandwidth, burst speed excepted. And I'd say that the speed improvement for mechanical drives has been very gradual. The Samsung F3 will allegedly bring 140MB/sec (sequential transfer) into the table, so while SATA-1 does look like it will become a bottleneck, I don't think that SATA-2 is going to any time soon. Of course, the story is different with SSD drives.

Will the new dx11 cards be PCI 3.0?

Will the new dx11 cards be PCI 3.0?

Nope

[j.o.s.h.1408]

Nope

so no point in waiting for pci 3.0 then

PCI-E 3.0 won't make a difference for quite some time....even the most powerful gfx card available today does not shine in PCI-E v2.0 vs PCI-E v1.1

SATA3 won't make much differnece, even with SSDs. 300MB/s should be enough for at least a few more generations.

USB 3.0 - Add-in controllers will be cheap to buy once you have a USB 3.0 device to plug in, if you haven't already got a motherboard with USB 3.0 on by that time.

[TooNice]

Sequential read of SSD is already at 260MB/s, pretty close to capacity. Sure having sequential read capped to 300MB/s may not be such a big deal, but I'd rather do without a bottleneck where possible.
I also find that add-in controllers are not exactly cheap when an interface is still quite new.
