Samsung Portable SSD T5 Review: Speedy, Durable External Storage


Samsung Portable SSD T5 - ATTO And AS-SSD Tests

ATTO is another "quick and dirty" type of disk benchmark that measures transfer speeds across a specific volume length. It measures raw transfer rates for both reads and writes and graphs them out in an easily interpreted chart. We chose .5kb through 8192kb transfer sizes and a queue depth of 6 over a total max volume length of 256MB. ATTO's workloads are sequential in nature and measure bandwidth, rather than I/O response time, access latency, etc.

Once again we see the Samsung Portable SSD T5 keep pace with the internal SATA-based solid state drives, but clearly outpacing the USB 3.0 thumb drive.

AS SSD Compression Benchmark

Next up we ran the Compression Benchmark built-into AS SSD, an SSD specific benchmark being developed by Alex Intelligent Software. This test is interesting because it uses a mix of compressible and incompressible data and outputs both Read and Write throughput of the drive. We only graphed a small fraction of the data (1% compressible, 50% compressible, and 100% compressible), but the trend is representative of the benchmark’s complete results.

The compressibility of data being transferred on the Samsung Portable SSD T5 had no impact on performance. Transfer rates were consistent across the board here.
