Read Performance Testing
Benchmark Results: The WD My Passport Edge 500GB portable drive had an average read speed of 92.2MB/s with a burst speed of 165.0MB/s and an access time of 16.74ms. The read performance is fairly linear and started out at 120.2MB/s on the outer edges of the platters before slowing to 54.4MB/s on the inner sectors.
Write Performance Testing
Benchmark Results: The WD My Passport Edge had an average write speed of 87.9MB/s with a burst speed of 149.9MB/s and an access time of 14.9ms. These are great write performance numbers!
Benchmark Results: The file benchmark results look good with ~110 MB/s writes for most file sizes over 16KB. Our real world testing and file backups bounced around a bit, but for the most part were between 75-100MB/s. The drive also felt warm to the touch during use, but never got much hotter than 32-34C during use.
