2020-09-30

High-performance bus-powered direct-attached storage units have become very popular, thanks to the advent of high-speed interfaces and technologies such as USB 3.2 Gen 2, NVMe, and 3D NAND flash. Flash manufacturers such as Western Digital / SanDisk, Crucial (Micron), and Samsung produce and market external solid-state drives (SSDs) under their own brand. In addition, manufacturers such as Patriot Memory also buy flash in the open market and bring their own value additions to the external SSD market.

Introduction

High-performance external storage devices use either Thunderbolt 3 or USB 3.2 Gen 2 for the host interface. Traditional SATA SSDs (saturating at 560 MBps) can hardly take full advantage of the bandwidth offered by USB 3.2 Gen 2. In the last 18 months or so, we have had a steady number of of NVMe drives behind a USB 3.2 Gen 2 (10Gbps) bridge entering the market.

Patriot Memory had a paper launch of the PXD external SSD back in April, and the units started hitting the market a couple of months after. The PXD has a gumstick form-factor, weighs 35g, and measures 31.5 mm x 103 mm x 9.8 mm. The aluminum body is sandwiched between two plastic tabs. It comes with a single Type-C port and two separate USB 3.2 Gen 2 cables - a Type-C to Type-C, and a Type-C to Type-A, each measuring 30cm.

In this review, we compare it against the following DAS units that we have reviewed before.
