These speeds are fine for copying small files but if you are doing large scale backups etc, you’re going to pine for the faster FireWire connection. We saw slightly better than that on the Mac USB 2.0 performance and it’s well below what the FireWire connection was able to muster. The test was run with the default runs of 0.5kb through 8192kb transfer sizes with the total length being 256mb.īenchmark Results: Clearly things are reads are maxing out at 35MB/s and writes at 27MB/s. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. ATTO measures transfers across a specific volume length. Overall the read speed maxed out at 74.30MB/s and the writes at 79.94MB/s.ĪTTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world. OS X 10.7.2 – XBench Benchmark – FireWire 800īenchmark Results: In the sequential tests, the FireWire rates were double than USB rates in most instances with the randoms being much closer. Next up is a free benchmark for OS X called XBench that also performs random and sequential reads/writes in 4K and 256K blocks. Clearly, using the FireWire 800 connection is the better way to go which most modern Macs have by default. The differences in writes were even more pronounced with the FireWire 800 hitting 40MB/s more at max.

Where the USB read scores topped out at 43MB/s, the FireWire 800 reads hit over 54MB/s. OS X 10.7.2 – SpeedTools Test Suite – QuickBench 4.0 – FireWire 800īenchmark Results: While the two charts look similar, have a look at the Y axis scale.

OS X 10.7.2 – SpeedTools Test Suite – QuickBench 4.0 – USB 2.0 We ran the test on both USB 2.0 and FireWire 800 to demonstrate the difference. It measures reads and writes, both sequential and random at various size intervals, similar to that of ATTO.

First up is SpeedTools Test Suite from Intech Software where we ran the QuickBench 4.0 benchmark.

Since the G-DRIVE Mini is targeted to the Mac folks, we did most of the testing on a 2.66GHz i7 MacBook Pro with a few benchmarks and also performed a few on our Windows test bench for comparison’s sake.
