USB 3.0 vs 2.0

[pparks1]

When does 3.0 come out?

It's already out.

Can you buy the laptop express cards yet? I know they made the PCMIA cards for laptops when USB 2.0 came out.

EDIT: I must be living under a rock. I feel stupid not knowing these weren't out yet.

I'm answering my own question. Here is a express card slot I'm going to buy:

OR http://www.frys.com/product/6149939?site=sr:SEARCH:MAIN_RSLT_PG

Thanks for letting me know that this is out!

USB 3 should be backwards compatible to USB 2.
I was thinking perhaps getting a HDD dock and then buy some external USB 3 HDDs. Have to wait a while though.

Just ordered this WD 1TB USB 3.0 The supplier ran CrystalDisk to test

Is that compatible when connected to a USB 2.0 port ???
or can it plug into a USB 2.0 ???

USB3.0 are backwards compatible. Obviously tho you'll only get USB2.0 speeds

When will you start being able to buy them built into laptops.

Also, where can you buy a usb 3.0 thumb drive?

Not readily available yet (but I doubt it will be much longer)

Check this out

I’ve been looking at this USB 3.0 Enclosure .. And this SATA 6.0Gb/s HDD to put in it.
But .. Would rather find an enclosure for a SATA 6.0Gb/s HD.

Take that WD external apart .. and tell us what HDD is in it .. please

lol..I don't have to. It's this

Thanks ... Not sure if this helps any .. But for a comparison ...
Here's a WD 1TB Green (32MB cache) in an External enclosure ....
connected via eSATA and then connected via USB 2.0

I'm wondering if SATA 3 and USB 3.0 are faster than the current drive technology can feed ??

Definitely. The devices that can feed it at full capapcity have still to be invented. Even SSDs are too slow.

SATA 3.0Gbps is still faster than hard drives can supply data...let alone SATA 6.0Gbps. Technically, SATA 3.0Gbs can support a max of 385MB/s...but with overhead it's more like 300MB/s...which is faster than any consumer mechanical or SSD drive out today.

With regards to USB 3.0...the spec calls for 4.8Gbps. With overhead, they say it will reasonably run at 3.2Gbps or around 400MB/s....which again is faster than any drive including SSD can dish out.

Here is a SATA III SSD to compare with: The new Crucial Real SSD C300.

Somewhere, I've read that the OS system is also a speed bottleneck ..
But I didn't understand what I was reading.
Just for grins ... I've compared my HDD in an external (USB 2.0 and eSATA) and connected directly via SATA ... With different systems in the same computer.
Looks like USB 3.0 is about the same as SATA 3Gb/s .. If anyone is interested

That's because the bottleneck is the drive itself. Both SATA 3.0Gbps and USB 3.0 are significantly faster than your hard drive. Thus, I would expect the tests to show the same thing as it's really the hard drive that is now being tested.

I figured that .. I'm thinking about trying a new HDD .. May order one this week ..
Then I can compare it to my Others
I've been looking for an enclosure that will take a SATA 6Gb/s HD and output USB 3.0.
Then I might go shopping for a new Mobo and Processor .. But the HDD will probably still be the Bottleneck.

What I was reading about the OS System had something to do with sector size and the way the files are managed in the OS.
I'm thinking it's a little early to get excited about all this ... It'll probably all be obsolete soon anyway.
My current computer is faster than I am anyway

I'm getting this and this instead of this.

I'm getting this and this ...

Any chance you can get them from Newegg ?? ....... This & This
You will post test results .. Right ??

My New HDD will arrive Tomorrow ..
Was going to wait to get the card and enclosure.

I'm in Australia so even if they ship here at all, freight will be expensive. I have organised a great deal with a local supplier. And absolutely I will post benchmarks

For right now .. I was interested to see what performance improvement I'd get with the twice sized cache and dual processors running @ SATA 3Gb/s .. as compared to This One
My main computer won't take the card.

Yeah, that'd be good to know
