Apricorn Aegis Secure Key 3.0 Review – Data Protection For Every Security Need


ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

Our initial ATTO benchmark results of 202MB/s read and 151MB/s write are excellent, considering that the Aegis Secure Key 3.0 uses on-the-fly encryption to ensure completely secure data storage.


Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.

The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance. For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs.

Looking at both the Crystal Diskmark and AS SSD Benchmarks, we can see that the Apricorn Aegis Secure Key 3.0 does very well with highly incompressible data, exceeding the listed read specification continuously, although falling just under with write data transfer just a bit.  We ONLY test in high sequential performance for this software as it takes much too long to let all tests complete, well in excess of 45 minutes.
