Disk Speed Test - RAID 0 Mode
With the 2 TB Western Digital My Passport Pro in RAID 0 mode, Disk Speed Test was able to achieve a peak throughput of just under 214 MB/s in both reads and writes. It's sobering to note that even with such high throughputs, the My Passport Pro is only fast enough to support the streaming of 1080p video at 30 fps, or 1080i video at 50 fps.
