Strictly speaking, the Wireless Plus drive doesn't use a Seagate hard drive because the company has yet to officially announce a 2TB 2.5-inch model.
Instead, it uses a Samsung SpinPoint M9T HDD (Seagate purchased the storage division of Samsung not so long ago).
The M9T is a 9mm model with a 5400RPM spinning speed, three 667GB platters, 32MB cache and rated latency and power consumption of 5.6ms and 2.3W respectively.
The manufacturer claims that the portable HDD should deliver up to 10 hours which is pretty spectacular but ultimately depends on usage. You can charge it via a PC while transferring files to it, which is pretty handy, but it will take much longer to fully charge it.
Seagate quotes three hours when connected to the wall plug and nine hours when connected to a USB 3.0 and in idle mode.
The Seagate Wireless Plus generally fared better than the comparable LaCie Fuel 2TB or the Samsung Wireless 1TB. It scored 2125 points on Futuremark's PC Mark 8 synthetic benchmark, higher than either.
The time it took to complete the 10 components of the benchmark suite ranged from 26.9 seconds (Microsoft PowerPoint) to 489.2s (Adobe Photoshop – heavy duty).
Keys: WoW = World of Warcraft, BF3 = Battlefield 3, PS L = Photoshop Light, PS H = Photoshop Heavy, ID = Indesign, AE = After effects, Ill = Illustrator, all times are in seconds, shorter is better.
