Samsung Portable SSD T3 – good things still come in small packages


We hooked up a variety of drives to our Surface 4 pro via USB 3.0 and ran a bunch of benchmarks.

  • Samsung Portable SSD T1 500 GB
  • Samsung Portable SSD T3 500 GB
  • WD My Passport Ultra (7200 rpm drive)

ATTO Disk Benchmark

We’ll start with the old trusted benchmark ATTO.

There is not much difference between the Samsung T1 and the new T3.  Both are really quick SSD’s.

 Left: WD My Passport Ultra

As a comparison we have the WD My Passport Ultra which is a small slim external drive with a HDD that spins at 7200 rpm. As expected it levels out at around 95 MB/s.

Again the difference is basically non-existing and the one that is there is due to variations in scores that we get when re-running the benchmark several times.


WD My Book Ultra

This benchmark shows in what conditions the HDD simply cannot keep up with a SSD.

Anvil Storage Utilities

The benchmark Anvil Storage Utilities is a bit special as it allows us to set up a kind of workload that mimics “real world” files when it comes to a mix of compressable and incompressable files.

Samsung Portable SSD T1 500 GB


100% compression = incompressable.


46% mix of compressed and incompressable files. 

Samsung Portable SSD T3 500 GB


100% compression = incompressable.


46% mix of compressed and incompressable files. 

In this benchmark we also see the same pattern as the others; the Samsung T1 and T3 are basically the same speed.

No Trim?

Support for the Trim-command has been largely undetermined both with the Samsung Portable SSD T1 and the T3. Using the program we get a “undetermined” rating for the drives. Trim support is important as it helps stop the degradation of speed over time so it is a bit dissapointing that it seems the Samsung Portable SSD T3 does not support it. However – we have been using the Samsung Portable SSD T1 for 7 months since the review and writing and deleting a lot of data on it and when we ran our benchmarks again for this review, albeit on a different computer, we still get similar performance as when it was new so it seems that there might be something Trim-like going on anyway or that the drive does not degenerate in speed as quick as one might think.
