Test Corsair EX400U: the portable SSD that wants to magnetize content creators

It seems that everything that is small is cute. Nevertheless, Failing to use such a qualifier for the SSD Ex400U of Corsair. Furthermore, it can nevertheless be said that its reduced size gives it a certain charm. Nevertheless, Large and 62 mm long, weighing just less than 100 g, the module is highly portable. Nevertheless, The magsa -face magsae compatible ring. Meanwhile, also allows it to hang securely on metal surfaces and iPhone, test corsair ex400u: portable ssd new even in reduced format of the 13 mini. In addition. In addition, In test corsair ex400u: portable ssd new addition. Meanwhile, A good point for content creators in search of an external SSD practical to transport, without closing additional pockets.

However. Nevertheless, Additionally. In addition. Therefore, if the grip seems solid, we regret that the ex400U does not also benefit from an IP54 certification, or at least resistance to falls of more than 1 m in order to ensure against any bad accident. However, This is all the more important on a module designed to be transported. In addition, the Corsair test corsair ex400u: portable ssd new EX400U has a single USB-C to USB-C certified 40 GB/S cable of 30 cm. For example, This is enough to use test corsair ex400u: portable ssd the module capacities as much as test corsair ex400u:. Furthermore, portable ssd new possible. but we would have appreciated a cable a longer hair, at the expense of use with smartphone via Magsafe, necessarily.

Question heats up, the ex 400U rises quickly in temperature once used to be used by CrystalDiskmark. Its upper aluminum plate leads heat and a peak at 41.6 ° C is observed. Nothing unbearable, but enough to let go “Oops, it’s hot” test corsair ex400u: portable ssd new After taking it in hand.

Cache memory management

SSD external obliges. the memory cover of the ex400U. which requests the nand more swift memory for optimal access to the data, is not up to the internal modules. However. this model comes out extremely well on our file test corsair ex400u: portable ssd new writing benchmark via HD Tune Pro. holding an average of 3345 MB/s in reading. 1824 MB/s in sequential writing, once test corsair ex400u: portable ssd past the CAP of 280 GB. A standard cache memory size for a 2 TB SSD, but whose velocity remains perfectly satisfactory.

Corsair had promised to use the speed latitude offered by the USB4 standard as much as possible. its ceiling at 40 GB/s. The promise is widely held, at least in our first benchmarks on Crystaldiskmark. Whether we talk about the reading (4058 MB/s) or writing (3715 MB/s) flow rate, the specifications are actually filled. With its USB4 accounting. test test corsair ex400u: portable ssd new corsair ex400u: portable ssd the ex400U rose – for the moment – far ahead of the competition on. our comparison. even the very good Samsung T9 tested recently.

How do these figures translate? The performance ratio compared to USB 3.2 is not from test corsair ex400u: portable ssd new simple to double. so much even the theoretical ceiling of 40 GB/s is twice higher. In our transfer test of a large file (27 GB). the ex400u reaches an average of 1707 MB/s in reading. 1338 MB/s in writing. that is to be speeds always superior to the Samsung T9, but also to the Corsair Ex100U, its direct predecessor.

Ditto for the transfer of several hundred photos, much more likely to saturate the bandwidth of the storage module. The ex400U then fluctuates around 1091 MB/s in reading. 1130 MB/s in writing, which is always much better than a limited SSD by the USB 3.2 interface.
