Nextorage NX-PS1PRO Series review
Share:
Blindingly fast for external storage, the Nextorage NX-PS1PRO delivers what we’ve been missing with USB 3.2 Gen 2 or even Gen 2x2. However, it’s not cheap, lacks an 8TB model and its cooling mechanism is passive. Backwards compatibility. Epic transfer rates.

Gets warm in use. Needs caching mode set to achieve speed. Not inexpensive. Why you can trust TechRadar We spend hours testing every product or service we review, so you can be sure you’re buying the best. Find out more about how we test. USB 4.0 has been around for a while, but relatively few devices use it, annoyingly.

The Nextorage NX-PS1PRO Series aims to remedy those missed opportunities by offering an external SSD that performs much better than an internally mounted M.2 NVMe. In theory, this device should be compatible with laptops that have USB 4.0 or Thunderbolt, delivering speeds up to 3,900 MB/s reads and 3,800 MB/s writing from a PC with these interfaces. Surely a candidate for our Best portable SSDs?.

It can be used with a USB 3.2 port (USB-C), but it will only offer roughly a quarter of that speed since USB 3.2 Gen 2 only offers 10Gbps, whereas USB 4.0 can achieve 40Gbps. The shape and scale of the Nextorage NX-PS1PRO are greater than many less rapid designs, as it needs to dissipate the heat generated by such high-speed transfers. But it's still small enough to fit in a jacket pocket or for accessories on a laptop bag.
