Seeing this, you may be a little confused. Why can’t you see the connection interface on the EX100U? In fact, after pulling out the dustproof bottom cover at the bottom of the EX100U, you can see the USB Type-C 3.2 Gen2x2 interface Hide here.

At the same time, the bottom cover can achieve dust-proof, simple appearance, interface protection, etc., which greatly reduces the frequent occurrence of dust in the USB interface, which causes the interface to oxidize, and then leads to poor contact after the interface has been used for a long time. The block next to the interface is matched with a brushed glossy decorative cover, which also makes the shape of the EX100U achieve a modified and simple look.

The outer ring is surrounded by a black trim strip around the light gray case.

Portable SSD Corsair EX100U 2TB Transfer Performance Test

The Corsair EX100U mobile solid-state drive uses a PC for data transmission performance testing, using Intel’s 12th generation i9-12900K processor with an ASRock Z690 Taichi Razer motherboard to build a Windows 11 test platform.

View the system’s detailed content and data of Corsair EX100U 2TB. The default file system is the exFAT mode, and the usable capacity is 1.81TB. In addition, the default settings for storage devices in Windows 10/11 operating systems are relatively conservative. The removal principle will quickly remove this safer setting, change the removal policy to “better performance”, and turn on “Enable write caching on the device” in the write cache policy to get better system performance, but turn on After these two functions, you must obediently use the exit disk drive function.

The default file system is exFAT, and the usable capacity is 1.81TB.
Enable better performance and write cache settings in the system.

First, check the basic data of Corsair EX100U 2TB through the CrystalDiskInfo software. It adopts the NVME Express 1.0/1.1 standard to support the SMART function, and the standby temperature is 50°C without the direct blowing of an additional fan.

CrystalDiskInfo software to view basic data.

Use CrystalDiskMark software to test the read and write performance of Corsair EX100U 2TB in an empty disk state. In the default mode, the test file capacity is set to 1GiB, and the read and write speeds are 1680.04 MB/s and 1546.23 MB/s.

The Q8T1 test results in the first column represent that a thread has eight queue depths, indicating that there are eight 1MB access items waiting to be completed in the work list. The corresponding situation is, for example, eight 1MB files of different files are read from or written to the hard disk simultaneously. Generally speaking, such operations are rarely performed.

For daily use situations or game players, refer to the range of items from QD1 to QD4. We switch the CrystalDiskMark configuration file to the real-world performance test, and the first column will be changed to Q1T1, although the running results will be lower than Q8T1. Some will be more in line with the performance of the actual daily use experience.

The reason is that the operating system often uses Q1T1’s mode of 1 thread and 1 queue depth in most daily operations, so Q1T1 is more suitable for daily use than Q8T1. In Q1T1 mode, the test file capacity, when set to 1GiB, the read and write speeds were 779.51 MB/s and 1274.57 MB/s.

Next, use PCMARK 10 to test the storage performance. Data Drive Benchmark (Data Drive Benchmark Test) is a data drive storing files as the main test object. It is very in line with the Corsair EX100U 2TB product positioning unpacked today. You can also use this item to test NAS, USB, memory card and other related storage devices. In this test, the Corsair EX100U 2TB has a bandwidth of 93.98 MB/s and an average access time of 303µs. The final total score of the test is 570 points.

In addition to the above-mentioned running test items, the test is carried out according to the photo file transfer of the actual daily use situation. This time, the 10.1GB ARW+JPG pure photo folder is used for the test, which is copied from the desktop to the EX100U. Writing test, the writing process takes about 18 seconds, the speed is up to about 792 MB per second, and then the photo folder is copied from EX100U to the desktop for the reading test, the whole process only takes 5 seconds, and the speed exceeds 3 GB per second.

The daily writing test of copying a 10GB photo folder from the system to the hard disk took about 18 seconds to complete.
It takes 5 seconds to read and copy files from EX100U to the system desktop.

The FastCopy software greatly increases the speed of copying a large amount of data by optimizing the thread work order in the copy operation. It is a software often used to copy a large amount of data and back up files. The author uses the same 10.1GB ARW+JPG photo Folder to test and copies the same desktop to EX100U for the writing test. The total time is 8.78 seconds, and the writing transfer speed is 1172.92 MB/s; copies the photo folder from EX100U to the desktop for the reading test, the total time spent is 8.48 seconds, and the write transfer speed is 1213.83 MB/s.
