It was 35 percent faster than USB 3.0 at writing our 10GB folder of files, 17 percent faster at reading those files, 14 percent faster at reading our large 10GB file, and a scant 6 percent faster at writing that file. Thunderbolt was much faster on these SSD tests than it was with the hard drive, and it was faster than USB 3.0 in all six tasks, though to varying degrees. Results were much faster than USB 2.0, but could not keep up with USB 3.0, which was always at least twice as fast as FireWire 800, and in the case of our 10GB file and Aja Write tests, USB 3.0 was three times as fast as FireWire 800. IDGДЇireWire 800 results were flat compared to the hard-drive tests except for the 10GB folder write test: At 62.8 MBps, it was 7.7 MBps faster than it was with the spinning drive. The slowest score for USB 3.0 and the SSD was for writing the folder of many small files, which it did at 144.7 MBps. Aja and file-read test results were a little slower-167 MBps-while reading a folder with 10GB of smaller files took just about 160 MBps.

We saw similar results with Aja System TestвЂ™s write tests.

When writing the 10GB file, the USB 3.0 connection hit nearly 200 MBps. USB 3.0 speeds, on the other hand, definitely benefited from the faster performance of the SSD. In this case, USB 2.0 was the bottleneck. We saw the same 40-MBps scores across all tests, with or without the hub. Again, USB 2.0 results were slow and consistent.

To try and remove the spinning-hard-drive bottleneck, we ran the same tests, but with an OWC Mercury Extreme Pro 6G SSD as the external drive. The Aja System Test Write scores were a little slower with the Hitachi drive connected directly to a USB 3.0 port on the MacBook Pro-107.2 MBps through the Belkin hub, the score was 106.1 MBps, and with the StarTech hub, the score was 102.5 MBps. Regardless of which test we ran or how we connected the drive, all of our USB 3.0 results were in the range of 112 MBps to 115 MBps range. Our USB 3.0 tests were pretty consistent. We used the 2GB File setting with 1920 by 1080, 10-bit, RGB frame sizes.

Finally, we ran Aja Video SystemsвЂ™ Aja System Test, a free benchmark thatвЂ™s meant to see how fast your system is and how it would perform under different video-editing circumstances. We ran a similar test with 10GB worth of smaller files and folders. Our tests included timing how long it took to copy a 10GB file to the external drive (in other words, to write the file) and then to copy that file back to the internal drive (read the file). (We used StarTechвЂ™s $61 6 Port USB 3.0 / USB 2.0 Combo Hub with 2A Charging Port with two USB 3.0 ports, four USB 2.0 ports, and a seventh USB port used for charging devices and BelkinвЂ™s $50 SuperSpeed USB 3.0 4-Port Hub.) We then ran the tests with the drive connected over FireWire 800 and via Thunderbolt with different enclosures. We ran the same tests again, but with the USB drive attached to each of two hubs.

Hard-drive testsДЇor our first test, we used a bus-powered, 2.5-inch Hitachi 750GB, 7200-rpm hard drive and ran a series of tests with it connected over USB 2.0 and USB 3.0 directly to our MacBook Pro. We also tested USB 2.0 and FireWire 800 speeds for comparison.

To give the tests the best chance of success, we connected the USB 3.0 drives to a 2012 15-inch MacBook Pro with a 2.7GHz quad-core Intel Core i7 processor, 8GB of RAM, and a speedy internal SSD drive installed. So we ran a slew of tests using both spinning and solid-state drives that had a variety of interfaces and were plugged in both directly to a computer and through a USB 3.0 hub. We wanted to see if USB 3.0 lives up to its hype, and if Thunderbolt is in fact a faster alternative.
