Portable hard drives used to be the poor cousins to their desktop counterparts - both in speed and capacity - making them somewhat of a compromise for those who need to take their work on the road.

We put hard drives through a durability test.
We put hard drives through a durability test.
That’s no longer the case, with portable hard drives now able to hold a terabyte (1TB) of data and with performance, in some cases, that matches or betters their larger desktop cousins.
We bought and tested seven 1TB portable hard drives and three solid state drives (either 64GB or 128GB) to see how much the gap has narrowed. The results are surprising and the next time you go looking for extra storage you might want to consider one that will fit in your top pocket.

How we test
The overall score is made up of:
- Performance (70%) is assessed with drives formatted as NTFS. The performance score is relative for the drives on test and not directly comparable to our previous hard drive tests. However, the average read/write throughput figures are directly comparable as they are raw data. Performance scores and real-time throughput for the Buffalo Ministation Portable were measured with and without the bundled TurboCopy software installed. The TurboCopy score is used in calculation of the Overall score.
- Ease of use (30%)
- Annual energy cost Based on the device being in standby mode 24h per day, calculated at 22c/kWh.
