G-Technology G DRIVE mobile PRO SSD (1TB) Review

ATTO DISK BENCHMARK VER. 3.05

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.

This is an outstanding ATTO result where we see performance increase commensurate with sample test volume increase.  The high read result of 2.8GB/s is about as high as it is going to get for Thunderbolt 3.  The write performance of 2.4GB/s is much higher than expected.

CRYSTAL DISK BENCHMARK VER. 5..5.0 X64

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 Crystal DiskMark results for the G Drive are much better than the Tekq Rapide and we couldn’t ask for much better than 2.8GB/s read and 2.5GB/s write.  As well, the low 4K results are just as impressive.

AS SSD BENCHMARK VER 1.9

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. Transfer speeds are displayed on the left with IOPS results on the right.

These marks are pretty exciting and certainly something we never thought we would be seeing through an external storage medium.  The throughput has already been discussed but how about 422K IOPS read and 404K IOPS write?  

ANVIL STORAGE UTILITIES PROFESSIONAL

Anvil’s Storage Utilities (ASU) are the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.

How you do thinking third party SSDs like Intel’s 2TB 660p will work with the G-Drive mobile Pro enclosure?
