We tested the A-DATA Xupreme 200x 32GB USB 2.0 Flash drive on an ASUS S62J ‘white box’ notebook with a Core Duo T2500 @ 2.0GHz. The Removable Storage test found in SiSoftware Sandra Lite XII was used to get read and write performance numbers of this USB flash drive and several others that we have tested over time on the same notebook.
The A-DATA Xupreme 200x proved to be the fourth fastest USB drive that we have ever tested when it came to read performance in the 256kB file size transfer test. Let’s see what happens to performance levels when a 64MB files test is run.
On the 64MB file test the A-DATA Xupreme 200x fell back to fifth place in the read test and tenth place in the write benchmarks. The A-DATA Xupreme 200x drives 28.80MB/sec read speeds are much better than a standard or value USB Flash drive, but the 7.47MB/sec write speeds left a little more performance to be desired.
To confirm the Removable Storage Benchmark that was used in SiSoftware Sandra we ran the Flash Memory Toolkit v1.20 file benchmark. This benchmark tests 1-5MB file sizes and found that in the 5MB file size test, the A-DATA Xupreme 200x had a peak write speed of 7.4MB/s and a read speed of 28.1MB/s.
