Pegasus2 R2+ Pod Testing

To begin our testing of the Pegasus2 R2+, we gave the SD pod a run through with our UHS-II SanDisk Extreme Pro. Quite surprisingly, we quickly figured out the pod was capable of UHS-II performance as our card reached 223 MB/s read and 131 MB/s write.

Swapping the SD pod for the SSD pod, we installed our 480GB Intel 730 SSD and gave it a run through DST. As you can see, we reached solid results of 465 MB/s read and 366 MB/s write.

 

Benchmarks - Black Magic Disk Speed Test

Moving over to our array, we start off with RAID 0, where we find the R2+ pushing 361 MB/s read and 350 MB/s write - quicker than the original Thunderbolt MyBook from WD and right with the 2Big from LaCie.

Moving over to RAID 1, we start off with read results coming in at 188 MB/s followed by write at 185 MB/s. Our RAID 0 testing put the R2+ ahead of the WD by a fair margin while the LaCie was a touch quicker.
