AS SSD Benchmark

If you're looking to see how fast your SSD really is, AS SSD Benchmark is one of the best tools out there. It runs a series of tests that push your drive to its limits, giving you a clear picture of its performance no smoke and mirrors.

First up, it checks both sequential and random read/write speeds, but here’s the catch: it completely bypasses the cache. That means you’re seeing the raw speed of your SSD, not some temporary boost. The tool writes and reads a full 1GB file, plus it throws random 4K blocks at your drive to simulate real world use. It even runs these tests with 1 thread and then with 64 threads to see how well your SSD handles multitasking. Oh, and it measures access time too so you know exactly how quickly your drive responds when you ask for data.

But that’s not all. AS SSD Benchmark also includes two extra tests that dig a little deeper. One test mimics everyday tasks like copying a bunch of large files, a ton of small ones, or a mix of both using your operating system’s built in copy functions. The other test checks how your drive performs with compressible and incompressible data, which is super useful since some SSDs work better with one type than the other. All in all, it’s a thorough way to see what your SSD is truly capable of.
