Finally, we ran Aja Video Systems’ Aja System Test, a free benchmark that’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 StarTech’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 Belkin’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 testsįor 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. dotcom-tools.We wanted to see if USB 3.0 lives up to its hype, and if Thunderbolt is in fact a faster alternative. if the server you're trying to get to is being slow, it might be that it is on a poor connection while your own connection is fine. That doesn't tell the whole story though. This tests the bandwidth, up and down, between you and one of Speedtest's servers. If you want to measure the bandwith of your connection, is a good place to start. ADSL and Cable connections have slower upload than download speeds (the A in ADSL is for asymmetric). The transfer will run at the speed of the slowest site. The 'real' speed of the provided network connection (eg ADSL is shared (contended) between many usersĪlso bear in mind that if site-A has 1Mbit upload speed and site-B has 10Mbit download, the speed of transferring from A to B will be, at best, 1Mbit. Network protocol overhead (http in the case of Archiware P5) Network latency (time taken for packet to travel through all the routers between A and B) Some examples below (in no particular order):

There are lots of factors that mean that these speeds will not be achieved in a real-world implementation. However, as anyone paying attention and using 100Mbit ethernet will find, when they copy a file from a server, the maximum speed they'll get will be around 8 MB/second and not 10 as the theory states above.
