Crystaldiskmark Vs Crystaldiskinfo

S.M.A.R.T. technology tracks various internal metrics of the drive, such as how many times it has spun up, how many errors it has corrected, and how hot it runs. CrystalDiskInfo aggregates this raw data into a user-friendly interface.

To the uninitiated, they often appear to serve the same purpose. They have similar logos (a cute anime-style mascot named Suisho Shizuku), similar interfaces, and they both deal with storage drives. However, confusing the two is a critical error. crystaldiskmark vs crystaldiskinfo

| Scenario | Recommended Tool | | :--- | :--- | | My computer feels slow. Is the SSD underperforming? | (run benchmark, compare to expected speeds) | | My PC randomly freezes or crashes. Is the drive dying? | CrystalDiskInfo (check S.M.A.R.T. and pending sectors) | | I just installed a new NVMe drive. Is it running at PCIe 4.0 speed? | CrystalDiskMark (verify sequential speeds) | | The drive shows 100% usage in Task Manager but low throughput. | CrystalDiskInfo (look for high error rates or reallocations) | | I want to see total data written to my SSD over its life. | CrystalDiskInfo (read "Total Host Writes" attribute) | To the uninitiated, they often appear to serve

The problem? S.M.A.R.T. data is raw hexadecimal. To a normal user, it looks like gibberish. | Scenario | Recommended Tool | | :---

is a disk benchmark utility. Its primary function is to measure the read and write speeds of your storage drives. It does not care about the health or lifespan of the drive; it only cares about raw performance metrics.

When choosing between and CrystalDiskInfo , the primary difference lies in their purpose: CrystalDiskMark measures how fast your drive is (performance), while CrystalDiskInfo tells you if your drive is dying (health) .

To understand CrystalDiskMark, you must understand the four key test scenarios it runs:
