Customer Review

It's small (but heavy: it must fit the 2 TB), it is beautiful, it is not noisy, it does not heat ... But as external hard drives are more likely to have these qualities, talking its performance! The disc has an actual capacity of 1.81 TB I tested its performance USB 2 and USB 3 with three file types.:

Gros: a film 8GB
Vehicles: 2000 music files 4 mo average (OGG format)
Small: 5000 TXT files of 5 kb

The results are those of everyday use (Windows Seven and with a recent SATA hard drive). No benchmark here, just a stopwatch, a calculator and SuperCopier software, which displays the copy speed in real time. Here's what I got:

USB 2: WRITING

Gros: 28-29 MB / s
Means: 20-25 MB / s
Small: 300-400 kb / s

USB 3: WRITING

Gros: 90-100 MB / s
Means: 68-70 MB / s (peak at 75 MB / s)
Small: 1.5 MB / s

***

USB 2: READING

Gros: 34-35 MB / s
Means: 25-28 MB / s
Small: 700-800 kb / s

USB 3: READING

Gros: 95-100 MB / s
Means: 80-85 MB / s on average (but peaks at 91 MB / s)
Small: 2 MB / s

I just wish there was a switch, because it almost hurts my heart to remove the cable while the disc is still spinning ... I do not always have time to wait snaps into eve.

Latest: the cable is a little less than 50 cm (40 cm without connectors).
