Sony's blazing fast BDX-S500U Blu-ray drive tests USB 2.0's true transfer chops
Here's a lesson in actual vs. theoretical. Sony Optiarc America has announced the new BDX-S500U external USB 2.0 Blu-ray drive capable of burning single-layer BD-R discs at smoking speeds of 6x or dual-layer discs at up to 4x. If you do the math, those specs imply transfer speeds of 27Mbps for single-sided 25GB discs and total burn times of roughly 20 minutes. That's great news for folks with PCs looking to use the high-storage medium or watch 3D Blu-rays -- except for one tiny hitch. See, USB 2.0's theoretical maximum transfer speed is 60MBps, but in the real world most are lucky to get even half that rate. According to tests by Techworld, those with certain USB 3.0 chipsets can even experience USB 2.0 rates as low as 11MBps. In that light, the BDX-S500U's impressive speeds -- just like Paul Walker -- may be too fast and too furious for its computer counterparts to keep up, making it a different kind of bag of hurt for buyers. While no official pricing has been offered the drive will go on sale later this month and online retailers are already listing prices in the range of $214 to $240.

Weekend project - DIY cheap 500GB external drive
Ah, the weekend; it stretches out before you like an open field, waiting to be plowed into furrows of laundry, errands, home improvements and recreation. Of course, for us, recreation = new stuff for our beloved Macintoshes! Ready to load up that shiny new Airport Extreme with some capacious shared storage to hold your iTunes library? Let's see... mix one part Staples $140 closeout deal on 500GB Maxtor PATA internal drive, add in one part external FW/USB enclosure with wicked flame graphics for $30... result: one excellent drive that wouldn't look out of place alongside the Mystery Machine. If you prefer the MacAlly cases (rugged!), there's a free shipping deal on those too.Now, for only $20 more you can have these guys assemble the USB-only case and drive for you, or these guys I've never heard of for only $145... but no pretty flames. Of course, if you want it to actually look good under the base station, then the Newer MiniStack is probably a better bet: the empty USB enclosure is only $60/$40 for an open-box unit, so add that Maxtor for some storage that's both functional AND stylish. Happy shopping!Update: The trend of the comments is decidedly unfavorable towards the reliability of both the Maxtor drive and the Metal Gear case, so: message received. Here's a deal on a cheaper DiabloTek enclosure, which makes up for the extra you'll spend on a Seagate or WD drive. If you'd prefer a SATA drive, there is a Maxtor out there for a strangely low $127, as pointed out by Trojan below.
Boot a PowerPC Mac from a USB2 drive
We all know that the Intel Macs can easily boot from USB drives, but that was never really a viable option on the PowerPC machines.At least, that's what most of us assumed. Mac OSX Hints jumps on Yet Another Opportunity To Prove Me Wrong, this time posting a step-by-step guide to booting your PowerPC Mac with a USB 2.0 device. The procedure has been tested on the newer iMac G5 models (with the ambient light sensor onward) and the 1.33GHz 12" PowerBook G4, but it's worth giving it a try on other newer PPC Macs, too. It's pretty tricky, involving some fancy Open Firmware manuevering, but the procedure looks promising.Give it a try and let us know how it works, ok?
Intel Macs can boot from USB drives
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.
