The synthetic benchmarks are good in the sense that you can see the theoretical speed of an external SSD, but the performance in the real-world is obviously more important. Considering external SSDs are basically used like USB-sticks, we use the same test.
10 GB reading and writing
First of all we tested how long it takes to write and read a 10 GB file. This shows how fast you can process large files, for example videos. We calculate the performance in megabytes per second.
Reading the 10GB file is quite fast at 410 MB/s and writing is done at the same speed.
1000x 5 MB reading and writing
We also tested how long it takes to read or write 1000 files of 5 MB. This is an indication of the performance of the drive when you use it to, for example, store digital photos or MP3-files.
Worth mentioning is that the performance of the different models varies quite a bit. The 500GB model is considerably faster than the versions with more storage capacity. Samsung might have to take a closer look at the firmware to solve this.
