AS SSD Benchmark FAQ
Straight answers to the questions people actually ask about AS SSD Benchmark — the version, the official site, Windows 11, the German interface, health data, and cloning. Everything here follows the documented facts about the program: final version 2.0.7316.34247 (January 2020), freeware by Alexej Schepeljanski, official site alex-is.de. This site is an unofficial resource and is not affiliated with the developer.
Is AS SSD Benchmark free?
Yes. AS SSD Benchmark is freeware by Alexej Schepeljanski and is distributed free of charge from the official site, alex-is.de. There is no paid version, no licence key, and no feature unlock — if a site asks you to pay for it, you are in the wrong place.
What is the latest version of AS SSD Benchmark?
The latest and final version is 2.0.7316.34247, built in January 2020. The program has not been updated since, and any site advertising a newer version or a 2025 or 2026 release is not telling the truth.
Is this the official AS SSD Benchmark website?
No. asssdbenchmark.com is an independent, unofficial resource site and is not affiliated with the developer. The official site is alex-is.de, run by Alexej Schepeljanski (Alex Intelligent Software). We link directly to the official file for downloads so you always get the genuine program.
Does AS SSD Benchmark work on Windows 11?
Windows 11 is not in the program’s official system list, which runs from Windows XP to Windows 10. In practice, community users run version 2.0.7316.34247 on Windows 11 successfully, but treat that as community-tested rather than an official guarantee from the developer.
Is AS SSD Benchmark portable? Does it need installing?
Yes, it is portable. There is no installer: download the ZIP, extract it, and run the executable. Keep the executable in the same folder as its language subfolder (for example en-US), otherwise the interface may fall back to German.
Why is the interface in German? How do I switch it to English?
The program defaults to German when it cannot find its language files. This usually happens when the executable was separated from the en-US language folder inside the ZIP. Extract the complete ZIP and run the program from the extracted folder, and the interface will follow the language files it finds there.
What is a good AS SSD Benchmark score?
There is no single good number, because scores depend on the interface and drive class: a SATA SSD, a PCIe 3.0 NVMe drive, and a PCIe 4.0 NVMe drive live in completely different ranges. Compare your result only with drives of the same class, and use the per-class guidance in our Score Guides section.
Does AS SSD Benchmark work on Mac or Linux?
No. AS SSD Benchmark is a Windows-only program. There is no official Mac, Linux, Android, or online version. Mac users usually turn to tools such as Blackmagic Disk Speed Test instead.
Can AS SSD Benchmark check my SSD’s health, SMART data, or temperature?
No. AS SSD Benchmark measures performance only; it does not read SMART attributes, health percentages, or temperatures. For health monitoring, use a dedicated tool such as CrystalDiskInfo, and use AS SSD Benchmark for what it is designed for: speed.
Can AS SSD Benchmark clone or migrate my drive?
No. It is a benchmark, not a cloning tool — it cannot copy your system to a new drive. For that job you need cloning software; our SSD Guides section compares the options, including the free Samsung Data Migration tool for Samsung target drives.
Is the download on this site safe? What is the file hash?
Our main download link serves the file directly from the official site, alex-is.de. The ZIP is 266,905 bytes and its SHA-256 is 56b80a3dde4537a77f9f7fb6bf45372b9b3d0a75e030d5373e5661913d7ef057, which we verified by downloading the official file ourselves on 22 October 2026. You can compare the hash of any copy you download against that value.
Why does AS SSD Benchmark say alignment BAD or ‘could not open physical device’?
An alignment BAD warning means your partitions are not aligned to the SSD’s block boundaries, which costs performance; our troubleshooting guides show how to check and fix it. ‘Could not open physical device’ is a known issue noted in the final version’s own changelog (‘Bugfix: Could not open physical device’) and is usually resolved by running the program as administrator.
