Western Digital positions its external hard drive WD_Black on the market gaming storage products. The classic version – the one tested – rubs shoulders with a version dedicated to the Xbox One: more expensive, this model is similar to the classic version, with the only difference that a 2-month subscription to the Xbox Game Pass Ultimate is offered. Of course, nothing technically prohibits using either version on a computer or with a PS4, especially as the hard drive is already formatted in exFAT.

Although a little thicker than those of a lower capacity, the WD_Black P10 5 TB remains compact enough for a 2.5-inch external hard drive. If the upper side is metallic, the rest of the case is in plastic. The whole seems resistant and the design, with a fairly large and clearly visible operating indicator, is quite interesting.

Western Digital has chosen an interface USB Type Micro-B. We would have preferred a Type-C interface, which tends to be generalized. However, this has no impact on the performance of the hard drive. The lack of a Type-A / Type-C adapter is also annoying, and that of a storage pouch is regrettable.


Inside the WD_Black P10 5 TB (WDBA3A0050BBK), there is a WD50NMZW hard drive, a model natively compatible with USB 3.0 (or USB 3.2 Gen1) and equipped with platforms operating at 5400 rpm, with a cache of 128 MB. The manufacturer announces data rates of up to 130 MB / s, without further details. Rather, it is in the middle of the theoretical performance displayed by other recent models of USB external hard drives.

Sequential rates (AS SSD)

In reading as in writing, the WD_Black 5 TB is placed in the average of the competing models. In absolute terms, the speeds are good and we exceed 110 MB / s in sequential access. We are still a bit far from the 130 MB / s max announced by the manufacturer.

Copy files (ASSSD)

With large files (ISO), the WD_Black 5 TB displays performances equivalent to those noted with AS SSD in the sequential bit rate tests. With medium-sized files (Games) or many small files (Program), this external hard drive even manages to stay above 70 MB / s where other competing models collapse below 60 MB / s, or even less.
