USB 3.0 Performance - Can You Make It Better?

Posted by Brad Wasson in "Digital Home Talk" @ 04:30 PM

http://www.tomshardware.com/reviews...turbo,3215.html

"Why is it that an interface that operates at 5 Gb/s never reaches corresponding transfer rates? Our investigation reveals that not all USB 3.0-based solutions are created equal, and we explore two technologies used to bolster the performance of USB 3.0."

Not getting the USB speed you felt was promised when you moved to USB 3.0? You may have seen advertisements suggesting USB 3.0 could bring you a maximum throughput of 625 MB/s. Not getting it? You are probably not alone. Tom's Hardware decided to have a look at the issue and see if there was a way to improve USB 3.0 performance. Indeed, there seems to be some good news coming in the future. In the meantime, a read through the Tom's article does a very nice job explaining why the theoretical throughput is not achievable, and what is being done to improve performance. It is a detailed read, but very interesting if you have pondered the performance question in the past.

Windows 8 to Work at Super Speed!

Posted by Hooch Tan in "Digital Home News" @ 02:00 PM

http://www.anandtech.com/show/4665/...ng-to-windows-8

"Windows 8 will be bringing with it native support for USB 3.0 controllers, writes Microsoft's Dennis Flanagan, Director of Program Management for the Devices and Networking Group. This is in contrast to previous versions of Windows, which continue to require separate drivers for USB 3.0 controllers."

I am old enough to remember the days when Windows did not come with native USB 2.0 drivers. That lovely reminder that when plugging in that USB device, warnings would pop up either telling me that the device could work faster and better no longer plague my dreams, but remind me of a time when drivers were a nightmare. Drivers still are a nightmare, but with a stable computing environment over the past decade has created a nice environment where some devices such as keyboards, mice and USB flash drives, worked without any hassle, at least to some basic level.

With USB 3.0, it looks like we will have to suffer a short period of time where extra drivers will be needed. Now if they could only make it so things like standard functions for printers and only need drivers for extra functionality, the job of an IT tech would be that much easier.

Verbatim Store 'n' Go SuperSpeed USB 3.0 Portable Hard Drive

Posted by Chris Sacksteder in "Digital Home Hardware & Accessories" @ 09:00 AM

Verbatim Store 'n' Go

Product Category: Portable Disk Drive
Manufacturer: Verbatim
Where to Buy: Amazon [Affiliate]
Price: $75.24 USD
System Requirements: USB 3.0 port
Specifications: Available in 500GB, 750GB, and 1TB capacities. Size 121mm x 80mm x 15mm. Weight: 115g. Supplied cable: 62cm.

Pros:

  • Small and light.
  • Good value.
  • Great warranty (seven years)

Cons:

  • Not close to "transfer speed up to 10x faster than USB 2.0"
  • Supplied cable is rather short.

Summary: At last, USB 3.0 devices are becoming widely available and at prices close to 2.0 disks. With transfer rates theoretically 10X as fast as USB 2.0, should you consider a USB 3.0 disk for backups and data transfer? Yes, but don't get your hopes too high. Your backups won't be going 10 times faster. Read more...

Seagate Releases The GoFlex Slim Portable Hard Drive

Posted by Jason Dunn in "Digital Home Hardware & Accessories" @ 02:05 PM

http://www.seagate.com/www/en-us/pr...ro1-goflex-slim

If you're looking for the most portable hard drive on the planet, look no further: Seagate has released the GoFlex Slim. It's a 320 GB, 7200 RPM hard drive that even inside the enclosure is only 9 mm thick. I'll be writing a brief review about this product in the coming weeks, but let me say this: it's crazy thin, and crazy fast - the USB 3.0 connection slurps down big files at over 150 MB/s based on a test I just did. Pricing is reasonable at $99 USD, and the drive has a really nice anodized finish. Mac compatibility right out of the box as well of course!

Convert USB 3.0 Ports to Accept eSATA Devices

Posted by Jason Dunn in "Digital Home Hardware & Accessories" @ 09:00 PM

http://www.engadget.com/2011/01/31/...legacy-externa/

"Newer Technology, Inc. announced today the NewerTech eSATA to USB 3.0 Adapter for using an eSATA interfaced equipped external hard drive with computers offering the 'SuperSpeed' USB 3.0 interface. The $29.95 MSRP adapter offers benchmark proven performance of up to 247MB/s reads and 206.4MB/s writes for the fastest data transfer rates available with external data storage/backup. NewerTech's exclusive distributor, Other World Computing (OWC)..."

Ports, ports, port. Sometimes it seems like we never have enough of them, or if we do, they're of the wrong type - this $30 accessory solves the problem of having an eSATA device and a USB 3.0 port on your computer. The read/write speeds are impressive, so if you need this kind of solution, it should be a no-brainer.

Seagate Sets New Areal Density Record for Portable Hard Drives

Posted by Jason Dunn in "Digital Home Hardware & Accessories" @ 05:32 PM

http://consumer.media.seagate.com/2...density-record/

"What's more significant about 1TB in this new form factor is that in order to make a drive at this capacity, Seagate reached a NEW areal density record-500GB-per platter! Areal density, which is also alternatively referred to as bit density, is the measurement of how much data can fit on an electronic storage device and is expressed in the number of bits that can be found in every square inch of space on the device. Translated into layman's terms , this essentially means that the greater the areal density, the more data can be stored in a smaller amount of physical space. Larger areal density also means faster transfer of data on a computer because the device drive doesn't have to look as far for the data."

It's quite staggering how much storage they can cram into a portable hard drive these days - yesterday afternoon a Seagate 1.5 TB FreeAgent GoFlex drive appeared on my doorstep, and I was amazed that 1500 GB worth of storage could be so small. I think this announcement is even more impressive though - Seagate has been able to shrink the chassis size down considerably (above is a before and after image), and even better boost speed. I've been told that the new 1 TB drive, using H2Bench as a measurement tool, cranks out 100 MB/s (not sure if that's read or write) compared to 83 MB/s from the previous 750 GB drive. Smaller? Faster? And USB 3.0 right out of the box? Sold!

Maximum PC's OCZ Enyo 128GB USB 3.0 SSD Review

Posted by Andy Dixon in "Digital Home Hardware & Accessories" @ 12:00 PM

http://www.maximumpc.com/article/re...b_30_ssd_review

"We've seen a few USB 3.0 external drives here at Maximum PC, and we do appreciate the long-overdue speed boost. It's nice to have file transfers limited by drive speed again, rather than the interface-the 33MB/s maximum was killing us. And while we appreciated the boost we got from USB 3.0 in WD's My Book 3.0 and the Vantec NexStar 3 SuperSpeed enclosure, the former was only as fast as the mechanical drive within it and the latter couldn't even match the speeds of the drives it enclosed."

USB 3.0 hasn't quite become mainstream yet, but it is good to see manufacturers starting to produce devices that make full use of the extra bandwidth capacity that USB 3.0 brings us. As the technology is still new it is therfore quite expensive at $410 for this external 128Mb SSD drive, but with the drive being to read files at and average of 180MB/s and write files at 166MB/s compared with a USB 2.0 drive that reads at 33MB/s and write files at 30MB/s you can see the performance boost that USB 3.0 will give.

Tom's Hardware Checks Out USB 3.0 Flash Drives

Posted by Hooch Tan in "Digital Home News" @ 02:00 PM

http://www.tomshardware.com/reviews...speed,2691.html

"Imagine if you were in a real-life role similar to Daniel Zavitz in the film Enemy of the State. You’re locked in your apartment when you realize you have to transfer a huge video file quickly before leaving. Bad guys will be busting your door down any second. If your options were based on modern USB 3.0 solutions, which drive would you grab?"

Flash drives were a great idea. When they first arrived, USB ports were already becoming common place and storage needs for transporting files were exceeding what the ancient Floppy drive could support. There were some alternatives, the most common being CD-Rs and CD-RWs, however, the process in using them was complex and annoying. I believe that flash drives really took off when USB 2.0 was widely adopted. Using older USB 1.1 ports, transferring files was still agonizingly slow. With USB 2.0, files moved at a cheerful rate. With larger files though, this no longer seems to be the case. USB 3.0 seems to be the solution, but have you seen the size of some of those drives? USB flash drives are handy because they are portable, and by "portable," I mean "fit-on-your-keychain-and-not-have-to-worry-about-it-stuffing-your-pocket" portable. Some of these look like they pack hard drives in them. I guess it will be a few more months, maybe years, before we see everyone using USB 3.0 flash drives, unless some of you out there need that extra speed more than pocket space.

When High-Speed Is No Longer Fast Enough

Posted by Hooch Tan in "Digital Home News" @ 02:00 PM

http://www.trustedreviews.com/perip...You-Want-It-/p1

"When it comes to backwards compatibility, you can easily plug USB 2.0 devices into USB 3.0 controller ports as they're exactly the same shape and size, differentiated only by their, blue rather than black, colour – so when USB 3.0 becomes universal you will still be able to use all your favourite stuff. You can also plug USB 3.0 devices into older ports so you could, for instance, plug your new USB 3.0 storage device into your mate's old computer to swap some files but it will of course be limited to the speed of the older standard."

Good old USB 2.0 has definitely been a boon to the computer industry. A wealth of peripherials have come out using the standard and with a single connector (usually) everything hooks up nice and easy. It kind of makes you wonder why it needs updating, but as anyone who has tried to transfer a lot of data on a USB drive can attest, it is starting to show its age. Enter USB 3.0, otherwise known as SuperSpeed USB! I am glad that they kept backwards compatibility with the new specification, however, I am saddened to learn that to make full use of USB 3.0, you need new cables. It is understandable, but now my tub-o-USB cables seems outdated and useless. With all that extra bandwidth (full duplex no less) what new peripherals will we see?
