G-Technology may be a lesser-known brand at first glance, but when I say names like WD and SanDisk, you’re sure to know what I mean. Of the three interconnected brands, G-Drive is profiled as the premium one, aimed mainly at creators and MacOS users. Mobile Pro SSD is a new addition to the family, which will impress with its Thunderbolt 3 connection and extreme speeds well above 1 GB/s.
Read: practical tests
Concerns about testing the drive correctly disappeared immediately when looking at the read. Here, the G-Drive won in basically all tests except the smallest 12–59 kB files, where the PXD has an above-average result. But let’s go gradually. The 9 GB file was transferred the fastest of the tested disks at a speed of 1445 MB/s, which is 5% more than with Fusion Drive. The fastest USB SSD, the P50, is up to 76% slower. We see the same 5% difference with 24–36 MB files, where we also exceeded 1 GB/s. The P50 lags here by 52%. Just below the 1 GB/s limit is the transfer of 5–10 MB files, where the difference compared to Fusion Drive is only 1%. The lead over the P50 also decreased to 37%. We also see a very good result with 427–1235 kB files, where the G-Drive achieves a 32% lead over the second fastest PXD. The smallest files are the fastest on the PXD, the G-Drive loses by 30%. So we can see that the SSD works properly and the slower writing in the previous chapter is real and not a wrong result, as I feared.
Read: synthetic tests
Synthetic reading tests are, except for one, fully in the hands of the G-Drive. In the sequential test we see almost 2 GB/s and a great result is also with 4K (64 threads), where the G-Drive is up to 3 times faster than the second fastest SSD. The access time of only 0.037 s is also great. 4K read is the only thing that the Mobile Pro SSD lags behind the P50, by 58%, which in practice is a difference of 13 MB/s.
