How do you perform performance tests on local storage units?

I use tools like CrystalDiskMark or ATTO to measure read/write speeds, and you can compare the graphs to see which one suits you better. Random access performance is especially noticeable in multitasking or games (like the pauses on loading screens), so I think it’s one of the most important parameters. In real‑world use, read/write speeds matter more for file transfers, but games constantly read and write data, making random access just as critical.

When it comes to performance testing in local storage, the simplest way is to start with the manufacturer’s datasheets, but the game changes once you throw real‑world scenarios into the mix. I use free tools like CrystalDiskMark and ATTO Disk Benchmark to measure read/write speeds; the former shows how disks perform on small files with 4K random tests, while the latter lets you see linear read/write bandwidth. For example, a Samsung 990 Pro NVMe will show 7,000 MB/s read/write speeds, but in a 4K Q1T1 test you might see numbers as low as 50 MB/s—that’s the load imposed by the file system. When it comes to random access, it’s all about IOPS (Input/Output Operations Per Second). The higher the 4K random read IOPS, the lower the latency you’ll experience when many small files are accessed simultaneously. This is felt directly in Windows page‑file activity or when loading shaders/assets in games. In real‑world usage, CrystalDiskMark’s tests with 512 KB‑1 MB blocks simulate game installs, while tools like FileCopy mimic actual file transfers. In my experience, games mostly run sequential small files, so NVMe linear performance shines, whereas video‑editing workloads benefit from both linear throughput and random IOPS. From a beginner’s point of view, the key metrics to watch are sequential read/write (Seq Q32T1), 4K random IOPS (QD32), access time, and drive temperature. If you’re on a laptop, Samsung/​SK Hynix tend to manage heat better, while models like the WD Black SN850X stand out for stability. In the systems I build, I constantly combine CrystalDiskMark, HD Tune Pro, and DiskBench to get average values—this way I avoid one‑off measurements and can test stability under different conditions.

I felt the same stress when I built my first PC. I even came across such contradictory sources online about performance tests that I was almost losing my mind. I did some simple measurements with CrystalDiskMark, running it in the background while loading games. For example, I compared an SSD to an HDD while loading a game—while the HDD took 2–3 minutes for about 80% of the games, the SSD cut that time roughly in half. I was just like you, wondering what random access actually means; it basically represents the small file reads/writes Windows does in the background. In my experience, those numbers don’t directly affect game performance, but they noticeably improve the system’s overall responsiveness (like in menus or when switching maps). In the end, I bought an ADATA SX8200 Pro that fit my budget, and it handled both games and file transfers much more comfortably.

Ehh bro, for local storage tests to see the difference between HDD, SATA SSD, and NVMe SSD, I’d first recommend CrystalDiskMark. For example, my old SATA SSD gave me around 500 MB/s read/write, while the new NVMe hits 3000 MB/s, no joke. In random access (like 4K tests) HDDs are around 100 MB/s, whereas SSDs can reach 30‑50 MB/s – that directly shows up in game loading times. In the real world, bro, AnandTech’s benchmark shows that even a 10 GB file transfer can be more important than the game itself. For instance, uploading Cyberpunk 2077 takes about 20 seconds on an NVMe, but 50 seconds on a SATA SSD. I personally do gaming and video editing – projects open on an NVMe at light speed. If you only need file backups, an HDD is fine, but if you want performance, I’d say grab a 1 TB NVMe and…warning
