The 850 Evo 500GB boasts read and write speeds of 540 to 520MB/s over SATA 6Gb/s. Since USB 3.0 offers slightly less bandwidth, the new T1 is limited to read and write throughputs of 450MB/s which is more than twice that of the fastest thumb drive we've ever tested.
Being based on an mSATA SSD, the T1 measures a compact 71.0mm wide, 9.2mm thick and 53.2mm deep (2.79 x 0.36 x 2.09 inches). More impressive than the T1's size is its weight, which amounts to no more than a thumb drive at 30 grams.
Being compact and light, the T1 feels sleek but it also looks the part despite being wrapped in plastic. This is admittedly a bit disappointing for a premium mobile storage product as the thin plastic case doesn't feel especially durable, and while it will likely survive being dropped thanks to its lightweight design, make sure no one stands on it once it has hit the ground.
Included is a 11cm USB 3.0 cable that's been custom designed for the T1, though there is nothing special about the cable besides its appearance. The cable is short as the T1 is designed to be used much like a thumb drive and thanks to its lightweight design it can hang from the cable safely while it's plugged in. If you want a longer wire any USB 3.0 cable will do the trick.
Samsung's portable SSD works effortlessly with both Windows and Mac PCs using the exFATfile system, eliminating the hassle of having to reformat for every type of computer.
Additionally, those concerned with security will appreciate the T1's support for AES 256-bit encryption along with an optional password to access the drive. Samsung has included some basic software to set up the T1 for the first time and this lets you apply a password.
The T1 is set at $180 for the smallest 250GB model, $300 for the 500GB unit that we're testing and $600 for the 1TB flagship. Samsung backs the drive with a three-year warranty. Ideally, we would have appreciated an extended five-year warranty, particularly for the $600 1TB model.
