ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. The test was run with the default runs of 0.5kb through 8192kb transfer sizes with the total length being 256mb.
Benchmark Results: The Kingston DataTraveler Locker+ G2 16MB fairs a little better than the specifications let on. Reads, only rated at 10MB/s hit nearly double that and writes, rated at 5MB/s, nearly tripled that throughput. All of this was on larger file sizes which is desirable for a flash drive since rarely would you be making extremely small file transfers in favor of larger files like JPGs, Word docs, etc.
CrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds. Note that CDM only supports Native Command Queuing (NCQ) with a queue depth of 32 (as noted) for the last listed benchmark score. This can skew some results in favor of controllers that also do not support NCQ.
Benchmark Results: Again, the speeds exceed specification on the sequential tests. The writes on the 4k files sizes crawled and the benchmark took forever to complete.
HD Tune Pro 4.01 is an extended version of HD Tune which includes many new features such as: write benchmark, secure erasing, AAM setting, folder usage view, disk monitor, command line parameters and file benchmark. It’s a popular benchmark and perfect for testing thumb drives.
Benchmark Results: The file benchmark here showed the writes more in line with the rated specifications but the reads still hit above 15MB/s. Again we see the larger file sizes faring better.
