Default USB 3.0 (SuperSpeed USB) is here

For those of you using external hard drives, you may want to know that USB 3.0 based devices are hitting store shelves now.

USB 3.0 (a.k.a., SuperSpeed USB) allows transfer speeds up to 4.8Gbps (roughly 10 times as fast as USB 2.0).

You can find adapter cards right now giving you USB 3.0 ports if you have an open PCIe slot on your PC. Here are some examples (and you'll be seeing more choices hitting store shelves soon):

http://www.newegg.com/Product/Produc...Add-On%20Cards

You can also find USB 3.0 external hard drives now, as well as hard drive enclosures supporting USB 3.0. Here's one example of an enclosure.

http://www.newegg.com/...16817145077&cm_re=usb_3.0-_-17-145-077-_-Product

Western Digital is now shipping a USB 3.0 My Book External Drive (available in 1TB and 2TB sizes), and you can also get one including a USB 3.0 PCIe adapter card. Amazon.com has them in stock now (and so do some other vendors around). Here's an example:

http://www.amazon.com/Desktop-Extern.../dp/B0031RG2JC

You can read more about that one here:

http://www.westerndigital.com/en/pro...sp?driveid=777

Some of these types of products (external hard drive enclosures, drives, etc.) supporting USB 3.0 have only started hitting store shelves within the past few weeks.

But, a number of manufacturers have already announced they're shipping these types of products. Here's one article on the subject:

http://www.pcworld.com/article/18656...y_arrives.html

So, if you need fast external storage, rather than going eSATA, you may want to take a look at the latest USB 3.0 offerings as they start showing up at more vendors.

Thanks, Jim. I was going with the 27" iMac, but I think I'm going to build another PC. Dell has a couple of good 27" monitors, and I think I'll have a better machine for the same or less money.

Any word on when/if USB 3.0 flash drives will be here?

The Super Talent USB 3.0 flash drives are supposed to be shipping already (they announced they'd started shipping last month). But, I can't find any on vendor shelves here in the U.S. yet. PQI is supposed to start shipping theirs, too.

It shouldn't be much longer before they start hitting shelves in the U.S.

P.S.

I am seeing some listings start to show up for some of them. But, they're not in stock yet. Here's one of the vendors Super Talent shows on their web site that usually stocks their products:

http://www.ewiz.com/detail.php?name=...SSD-RAID-Array

These drives aren't going to be cheap though. ;-)

Basically, this one is using built in RAID 0 in the Flash Drive for increased performance (keep in mind that just because the interface is faster, you'd still need a controller and flash memory that can take advantage of the increased speed) and is available in 64GB and 128GB sizes (it's supposed to be shipping now, but it's still not on dealer shelves).

Just saw a PC Mag article by Michael Miller - testing an external drive for laptops:

I read it yesterday and almost left some comments, since it seems pretty obvious to me that something must be wrong with the test procedure (or the Express Card controller and/or drivers being used with it) , as it looks like he wasn't even maxing out what you can get from USB 2.0 with the tests

IOW, that test doesn't "jive" with other tests I've seen of USB 3.0 hard drives, which tend to test several times as fast as similar USB 2.0 attached hard drives. Here's one example:

http://www.pcworld.com/article/18597...s_through.html

Here's another example, that also includes benchmarks of the same Black Armour drive the author of that article you posted a link to wrote:

Yeah, it's interesting to see these kinds of review "anomalies." That's one of the helpful things about the Internet, isn't it? It's so useful to see multiple takes/reviews of the same item.

I decided many years ago to not be a "new technology" adopter - as soon as the stuff comes out. It's a lot cheaper and less frustrating to let others find the problems, first. The quick turnover cycle for tech products means, at least to me, that most of us are "beta testers" anyway, even though we think we're paying for a mature product.

Here's the relevant excerpt...

Quote:
\Because almost no machines come with USB 3.0 ports, the drive ships with an ExpressCard USB 3.0 connector and software that makes it work with a Windows laptop. Because ExpressCard doesn't carry as much power as USB, you also have to plug the card into a USB 2 port.
In other words, he's basically running a hyped up version of USB 2.0, and no real comparison is being done.

I don't think that's what he's saying, Dave. I read this excerpt as the device is only drawing extra power from the USB 2.0 port; the data is still going though the ExpressCard slot.
