USB 2.0 posts

Some Mac users just don't want to be limited to one monitor, but would like two... or three... or more.

Having only one display port on your Mac can put a real crimp in your plans to be the master of the monitor universe, so NewerTech has launched the USB 2.0 Display Adapter. The adapter, with a suggested retail price of US$96.00, lets users add an extra HDMI, DVI, or VGA display to their Mac. Up to four of the bus-powered adapters can be hosted on each Mac, and each adapter can support a maximum resolution of 2048 x 1152. The device also supports Windows, and can be used with Boot Camp.

Cloning and extended desktop modes are supported by the USB 2.0 Display Adapter. A secondary adapter (VGA and HDMI adapters are supplied) must be attached to connect VGA or HDMI displays. Unfortunately, the adapter doesn't allow OpenGL acceleration, so applications that use Quartz Extreme, Quartz Composer, and other related frameworks are not full supported. This means that Keynote, iPhoto, and iMovie will not see the benefit of OpenGL acceleration.

To use the adapter, your Mac must have an Intel processor and be running Mac OS X 10.4.11 or better.

Are you wondering what to do with the 2.5" SATA drive that you yanked out of your MacBook or Mac mini so you could replace it with a SATA Solid State Drive? For $19.99, the OWC Express USB 2.0 bus-powered enclosure provides a new home for that old drive so you can use it as a backup or spare drive.

The Express enclosure is just slightly larger than an iPhone at 3.07" x 5.12" x .55" (78mm x 130mm x 14mm), and weighs just 2 ounces (56g) empty. Just toss in your old 2.5" SATA drive and you have a bus-powered USB 2.0 drive that easily fits in your pocket. You can also shop around for new bare SATA drives; a 500GB, 5400 RPM drive can be had for as low as US$97 (I'm sure you can find them for less!), making for a low-cost and portable backup solution.

There are other similar USB 2.0 enclosures out there; MacAlly's PHR-250A (US$19) and StarTech SAT2510U2 Infosafe (US$17.96) are about the same size and weight as the Express, while the Vantec NexStar SX NST-285S2-BK (US$22.02) and Sabrent EC-UST25 (US$14.97) are larger and heavier.

For those of you who were waiting to buy a Data Robotics Drobo, wait no longer!

Data Robotics announced the release of the second iteration of their 4-bay expandable storage solution, Drobo. Many potential buyers were aghast at the original version's lack of FireWire, so the company added FireWire 800 (FireWire 400 compatible) ports to the original USB 2.0 connection. Transfer speeds with FireWire 800 are expected to be about double those of the USB connection.

The new Drobo also has improved software. The old model would see a drop in performance after the array reached about 50% of capacity. With the new software, performance remains steady regardless of how much data you've packed into your Drobo. Data Robotics says Mac users can expect a performance increase of 10 - 200%.

When new, higher-capacity drives become available, you'll be able to expand the capacity of your Drobo to up to 16 TB. That should be enough to handle all of my TUAW comment email! The second-generation Drobo becomes available in about three weeks, and the original $499 price tag is still in effect for an unpopulated box (no drives included).

Updated to note that no FireWire 400 ports are included. Thanks to Neg and See3Pio for the heads-up!

Do you need a bus-powered 1 TB hard disk? You're in luck - LaCie announced the Little Big Disk Quadra today.

Available in early July, the Little Big Disk Quadra uses a pair of drives in a RAID 0 configuration for speedy response. My personal concern is that if one of the two RAID drives goes out, you'd lose all of the data in the array. Although LaCie states that it's "Compatible with Time Machine", the Little Big Disk Quadra is probably better-suited as a scratch drive for video work on the go.

This is a tiny drive considering the capacity - the outside dimensions are 1.6 x 3.3 x 5.5 in. (40 x 85 x 140 mm) and it tips the scales at 1.4 lbs (650 g). You don't need to use the included AC adapter when using the Little Big Disk Quadra with FireWire 400 or 800, but you will need it when using the drive with eSATA or USB 2.0.

Some sites are stating immediate availability, but LaCie has confirmed that it will be several weeks before the Little Big Disk is available.

Last week Dan posted about the new complications of Intel OS X drives not being bootable on PowerPC Macs, and vice-versa. The report came from Jon 'Wolf' Rentzsch, who recently updated the originating post with some specifics about booting and partition schemes, with one fairly positive detail: Intel based Macs can boot from USB2 drives.

While many in the Mac community prefer FireWire over USB2 for various reasons, this will nevertheless open the doors for OS X to be bootable from more external hard drives. What are the chances I can bring a slimmed down OS X installation along with me on a 2 or 4 GB USB2 flash drive? I guess a geek can dream.
