Is the Surface Pro a tablet or a laptop? Well, let's put it this way: benchmarks put it squarely in the laptop category, leaving Apple and Android tablets in the dust.
It's a "full blown" SSD, wrote Anand Shimpi of Anandtech, referring to Micron Technology's C400 solid-state drive in the Surface that Anandtech tested.
The Micron SSD posted speeds of 400 megabytes-per-second when reading data and just under 200MB/s in writes.
"The fastest sequential transfer rates I've managed on the 4th generation iPad are typically on the 20-30MB/s range," he wrote, adding that the flash drives in most tablets are, by comparison, "horribly slow."
Other benchmarks such as Mozilla Kraken (above) show just how fast Pro is compared with tablets and high-end smartphones.
There is a downside to blistering data transfer speeds and a fast processor, however.to address concerns with battery life.
While the iPad has a rated 10 hours of battery life, the Surface Pro has trouble squeezing out much more than four hours.
So, does all of this make the Surface Pro a laptop? Internally, the answer is obvious: it's clearly an ultrabook, replete with an Intel Ivy Bridge processor, 4GB of memory, and a laptop-class solid-state drive.
Future iterations of Surface will undoubtedly offer better battery life as Intel moves to its more power-efficient Haswell generation of processors this summer and Microsoft tweaks the design to allow it to run longer on one charge.
For now, Microsoft has bragging rights to the fastest "tablet," albeit with very untablet-like battery life.
