External drives are very common - mostly people won't put much into deciding what to buy. I myself have repurposed 2.5" SSD by using an external adapter case. But reviewing the Samsung T5 Portable SSD made me realise some of the missing features.
First of all is its very small size. Compared to a 2.5" external adapter the Samsung T5 Portable SSD is miniscule - it measure 57.3mm by 74mm and it's only 10mm thick. This is smaller than your usual business card. It fits in the palm of your hand and most importantly on your shirt pocket, without being too obvious.
Next you will notice the metal unibody with rounded long edges. This gives it a bit more durability than the usual external cases which are just two thin metal sheets slapped into a plastic frame. This means the Samsung T5 Portable SSD can stand drops of up to 2 metres.
Inside the box you will find the drive itself and two cables - USB-A to USB-C and USB-C to USB-C. This means you can plug the Samsung T5 Portable SSD to laptops in general and to other devices with USB-C ports only, such as Chromebooks.
You can plug to the Samsung T5 to an Android device (providing the Android uses USB-C port) and instantly see the storage on your smartphone or tablet, allowing you access to a lot of space for backups or file transfer - you will find the Samsung T5 with storage space from 250 GB to 500 GB (the blue design) and 1 TB to 2 TB (the black version).
The Samsung T5 comes with pre-loaded Windows and Mac software (Android also available from Google Play) that allows you to set password protection for your content. The content will be encrypted thanks to its AES 256-bit hardware encryption built-in. The software also allows you to check for firmware updates for the device.
With support for USB 3.1 Gen2 you will see transfer speeds of up to 540 MB per second in optimal conditions. In my tests I've seen it reaching speeds of up to 400 MB per second, obviously limited by my existing hardware.
The drive comes pre-formated with the exFAT filesystem so it's usable out of the box with all target platforms.
