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.
TxBench is one of our newly discovered benchmarks that we works much the same as Crystal Diskmark, but with several other features. Advanced load bench-marking can be configured, as well as full drive information and data erasing via secure erase, enhanced secure erase, TRIM and overwriting.

TRUE DATA TESTING
For our true data testing scenario. we elected to put a number of portable SSDs side by side, including a TB3 drive as well as the Samsung T7 being used with the USB 3 adapter. The test consists of placing four 15GB data files (pictures/video/music/OS data) onto each device and copying that file to a new location on that device.
A bit surprising is the fact that the new T7 completed its downloads faster than the T7 Touch that we reviewed in January. Downloading with the USB 3.1 to Type-C cable shows how much slower USB 3.1 is, as can be seen with the times in the last result on the right.
REPORT ANALYSIS AND FINAL THOUGHT
If you are looking for a portable SSD, you might want to take a good look at this Samsung Portable SSD T7. It is available in a number of capacities up to 2TB, has a 3-year warranty, is rock solid in its build and it’s performance of 1GB/s read and write will attract those into media.
Although we might really like to see prices come down just a bit, the T7 has very competitive pricing and mass availability, which is all one might ask for with a product of this build.
