So time to test these suckers, I did some benchmarking using ATTO Disk Benchmark. Whilst testing the content never changed I just swapped the HDD from one enclosure to another.
As you can see the Revoltec enclosure reached a peak of 26 Megabytes a second on USB no bench for the firewire cause the Revoltec dint have a firewire connection.
Now lets see how the Vantec NexStar3 preformed…
And hey look at that its faster beating the Revoltec one with over 1 Megabyte in speed difference, lets have a look at the firewire results. The firewire clocked in at about 20 Megabytes Write and 25 Megabytes Read. Now the reason why it’s a little slower then USB is because of the bandwidth since firewire is running at 400Mbps and USB2.0 at 480Mbps, however that doesn’t explain why the Read is just about the same as on USB, so I tried another test writing a 7Gigabyte file.
USB vs. Firewire
| USB | firewire | |
| Size | 7572881408 | 7572881408 |
| Time | 285047 ms | 395375 ms |
| Transfer Rate | 25,336 MB/s | 18,266 MB/s |
So what’s causing this? Well I don’t have a clue but I recon the Vantec’s firewire ports aren’t that super. Apparently Read isn’t a problem but writing is, but I get similar results on other PCs as well, I’ve asked Vantec for an explanation but till now I still had no response what so ever…
