Not much to say here. We fired up the HD Tach v22.214.171.124 and prepared the full length test:
The full bench test scans the entire capacity of the module and creates a graph with its average reading/writing performance:
The performance indicates that we have to do with an "entry level" product here.. The reading was linear at an average speed of 20MB/sec, while the writing was slower with 11.4MB/sec.
