Top 10 best external hard drives 2.5-inch


Easy to transport, these portable hard drives offer storage capacity of 120 GB to 4 TB and good performance thanks to their USB 3.0 interface.

For all its files always at hand, the simplest solution is to store them on a portable external drive. 2.5-inch format, they offer much more capacity than a regular USB drive – 500 GB to 2 TB – but still compact enough to fit in a bag or in a pocket. In addition, their prices drop regularly: a 1TB drive is trading around 100 euros, a very affordable price to store movies, music, and photos.And the champion of the genre, Seagate, downright welcomes 4TB of data by combining two 2 TB drives of only 9.5 mm thick each. The 2.5-inch internal hard drives become finer, hence the appearance of external models “Slim” measuring less than 1 cm thick for 500 GB or even only 1.2 cm to 2 TB.



High data throughput USB 3.0, especially for large files

All models in our ranking feature a USB 3.0 interface that offers excellent rates for file transfers, especially if their size is high. With videos, hard drives beyond 100 MB / s read and 90MB / s write. The Touro Mobile Pro of HGST going even above 130 MB / s because it embeds a disk at 7200 revs / min instead of 5400 rev / min. But the LaCie P’9223 goes even further by exceeding 200MB / s! For this, the manufacturer no longer uses the mechanical drive, but an SSD (Solid State Drive). Besides speed, flash memory usage increases the robustness of the drive that contains thus no mechanical part.The only problem, the capacity is reduced: the only 120GB, resulting in a cost per gigabyte ten times higher than a mechanical hard drive. If the disks are proving swift for large files, they drop considerably with the file smaller. For JPEG photos, play speed remains above 100 MB / s but writing falls to 40 MB / s or 20 MB / s for some models.

Beyond pure performance, it is also the design and strength of the housing that makes the difference. If you need to transport your disk every day, choose a model with a metal case, stronger than plastic. Finally, the bundled software may be a significant factor of choice if you want to use the portable drive for backing up your computer or store sensitive files by protecting them with a password. In this area, offering manufacturers is sometimes very attractive.
