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.
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.
REPORT SUMMARY AND FINAL THOUGHTS
If you are in the business of needing an encrypted flash drive Apricorn has a solid reputation and is just about the best in the business. I have been using their Aegis Secure Key 3.0 for my own business for several years and it still works as good as the day I received it. Having said that, I have a very deep appreciation for the 480GB capacity and decent data transfer speed of that flash drive, just over twice as fast as the 3NXC we are reviewing today.
The Apricorn Aegis Secure Key 3NXC certainly holds its own though, in that it is the worlds first encrypted flash drive with a USB 3.2 Type-C connector and that opens the doors to what storage devices it can connect to. USB Type-C is the standard. Its security features on both the business and personal level are about as good as it gets and have been very well thought out. Let’s face it. There is nobody that is getting data off this device physically or through hacking unless they have the password. This has been the standard of Apricorn for several years and is the cornerstone of their business. If we had to make a suggestion, increase the capacity and up the data transfer speeds to match the Secure Key 3.0.
