Buffalo unveils 'world's most capacious' pocket hard drive
Portable storage, and lots of it
Buffalo has launched a 320GB handheld hard drive, which it claims is the world’s first 2.5in drive to boost such a quantity of storage capacity.
Buffalo's MiniStation TurboUSB
Dubbed the MiniStation TurboUSB, the range is protected by a “tough armoured outer case”. The 5400rpm hard drive is powered through a USB 2.0 connection, with the cable wrapping neatly around the device’s outer rim. File encryption and auto-backup software also ship with the drive.
Buffalo said the drive’s compatible with all Windows OS versions and Mac OS X - including the recently launched Leopard.
The MiniStation TurboUSB will available from next month, with prices ranging from £46 (€70/$93) for an 80GB model to £155 (€195/$310) for the 320GB version.
USB 1.0 / 1.1 are not capable of supplying the juice hence a power jack is supplied for backward compatibility.
As said above, they're common place now... very few devices i have actually ship with the DC adaptor anyway, but it's there if you need it...
ooh nit picky picky picky
I don't know any other 2.5" portable hard drive that can't be powered by USB alone, but maybe, just maybe they put that power connector on their for other uses of the hard drive, eg mp3 storage in a car attached to a car stereo.. that requires external power almost always!
I think someone is a little tired and cranky and needs to go for the afternoon nap!
Re: it's powered... why
"Look carefully on that picture and it has a DC-in area. That mean it has to be powered to use?"
Not necessarily - there's a better than even chance that it'll come with a 'dual headed' USB cable so it can take power from two USB ports rather than one. The DC-in socket is handy if this isn't possible for some reason.
So, it'll probably USB powered *or* mains powered at the discretion of the user.
Haven't been around long, have you?
Ignore the DC input. If you know anything about PCs, USB, and HDDs, you'd know exactly why it's there on a USB-powered HDD.
USB-powered hard drives operate outside of powered USB specifications. Even within spec, not all USB ports are powered, and I don't just mean those from an unpowered hub. Apple notebooks have long shipped with unpowered USB ports to sell their iSight firewire web cams (though they claim that it is to save batteries of something). Users of these notebooks will either need a direct power plug or a medusa cable that draws power from either A: additional ports or B: a power plug (often a USB-charger wall plug).
Just like Western Digital USB-powered 2.5" drives, the auxiliary power is optional.
