We put the 256 GB AXE USB flash drive through a detailed test. You can find the test result / test report here:

AS SSD Benchmark

Standard performance test

The standard test was performed with a 1 GB file. A total score of 118 points was achieved.

AS SSD Benchmark Screenshot: TEST: AXE Speedy 256GB

AS SSD	Read:	Write:
Seq in megabytes per second	392.42 MB/s	196.20 MB/s
4K in megabytes per second	12.31 MB/s	2.54 MB/s
4K-64Thrd in megabytes per second	12.48 MB/s	3.75 MB/s
Access time in milliseconds	0.415 ms	0.811 ms
Score	64	26
Total score	118

Copy performance test

A common everyday scenario is simulated here. Three test folders are created:

ISO (folder with two large files)
Program (folder with many small files)
Game (folder with small and large files)

The three folders are copied using the Windows copy command (cache remains enabled). The real-world test from 15 January 2026 shows performance during simultaneous write and read operations. The lower the duration, the better.

AS SSD Copy Benchmark	Transfer rate:	Duration:
ISO two large files	262.63 MB/s	4.09 s
Program typical program folder with many small files	106.01 MB/s	13.27 s
Game a game folder with small and large files	118.67 MB/s	11.64 s

Compression performance test

Here, speed is measured depending on how compressible the data is.

CrystalDiskMark Benchmark

Similar to AS SSD, two sequential and two random performance tests are carried out here and the write and read speed (manufacturer: 400 MB/s and 200 MB/s) the AXE USB flash drive is determined.

HD Tune Pro long-term test

A long-term test was performed to fully utilize the storage. You can see from when a possible cache is full and write performance drops. A test file of 10 GB was written to the medium.

HD Tune Pro Benchmark

HD Tune writes a 1 GB file to the 256 GB AXE USB flash drive. The transfer data of the read speed is displayed graphically. The minimum, maximum and average values are also determined. The measured access time and burst rate are also shown.

ATTO Disk Benchmark

Here, a 256 MB file is written to the 256 GB AXE USB flash drive multiple times. The I/O block size varies (from 512 bytes to 64 megabytes). The larger the blocks, the faster writing and reading usually becomes.

SSD-Z Benchmark

Similar to HD Tune, a 500 MB file is written to the 256 GB AXE USB flash drive here. The transfer data is displayed. The more consistent the line, the better. Unfortunately, the tool no longer works correctly from around 4,000 MB/s and no line is displayed (and sometimes incorrect min/max data is shown).

Power consumption

The following screenshot shows the USB flash drive's power consumption at idle (standby) and during a read operation followed by a write operation. The drive consumes approx. 0.21 watts at idle. Maximum consumption was approx. 0.75 watts.

The benchmark test review was performed on 15 January 2026.
