Seagate's, 500GB Slim is a sexy and thin portable drive. Indeed, at first sight, several colleagues mistook it for a smartphone. What that says about phones is another matter. The downside to the super-svelte, 9mm thick Slim is limited capacity: it's available only with 500GB.
Fortunately, there's no need to go in for the old "beauty is only skin deep" truism, as the Slim is also a very good performer. It read our 10GB mix of files and folders at 62.2MBps, which was good for first place in the roundup; but it fell off the pace slightly when writing those files: 39.5MBps— about 9MBps slower than the WD My Passport and My Passport Edge. It read our large 10GB file at 104.1MBps and wrote it almost as fast: 94.6MBps; again, slightly off the pace set by the WD drives, but faster than voth its Satellite stable-mate and the Rocstor Lancer LX.
The Seagate Dashboard software provided with the Slim lacks the utilities and security features of WD's SmartWare bundle, but it does offer local and cloud backup support. It can also interface to Facebook, Flickr, and YouTube for uploads. A 4GB, 12-month subscription to Seagate's Cloud Storage service comes with the drive.
The Slim is a USM (Universal Storage Module) so you can use bridge adapters other than the USB 3.0 adapter that comes with the drive, as well as Seagate's GoFlex Net dock. Unfortunately, there doesn't seem to be any other adapters that match the styling drive's styling as closely as the bundled USB 3.0 adapter does.
This drive turned in a good performance, but the reason for buying the Satellite Slim is its undeniably eye-catching looks. Just be careful handling this: that super-thin case won't likely provide a lot of shock absorption if your drop it.
This portable hard drive has style in spades, plus good performance and software. It also is a universal storage module that will accept interfaces other than its standard USB 3.0 adapter.
