Benchmark:Seagate Backup Plus Slim 1TB

Sadly, my HGST Touro drive is giving out. The drive itself is fine, it’s the USB connector that seems to be going bad. To avoid a difficult data recovery situation, I replaced it early with a Seagate Backup Plug Slim 1TB drive. Let the benchmarking begin!

TL;DR

The quick summary for those who don’t care to read all the metrics, over a USB 3 port, the drive maxed out at 129 MB/s sequential write and 128 MB/s sequential read.

Note
This benchmark was performed using a tool I wrote in bash called dd-bench. It’s open source (GPLv3), so please feel free to use it and send feedback and pull requests to nullspoon@oper.io.

1 KB Block Size

Note
The other block size benchmarks go up to 20 GB of data. Due to the time consumption of doing that in 1 KB increments, I capped this one at ~80 MB.
