CCrystalDiskMark as the Standard Storage Benchmark

Posted by

Have you just purchased a new NVMe SSD and want to make sure it's as fast as advertised? Or are you feeling like your device is starting to slow down and want to check its health? CrystalDiskMark 9 is the answer.

What is CrystalDiskMark ?

CrystalDiskMark is free, open-source software used to test the read and write speeds of storage media, from hard disks (HDDs), SATA SSDs, NVMe SSDs, to memory cards (SD cards) and USB flash drives.

The current version 9 is an improvement over the previous version, bringing a fresher interface and retaining the test profile feature introduced in version 8.

Key Features of CrystalDiskMark 9

Dual Test Profiles :
- Default (Peak Performance): Measures the theoretical maximum speed your drive can achieve (often used to verify manufacturer marketing claims).
- Real World Performance: Real World Performance: Measures performance in real-world, everyday usage scenarios. This is typically lower but more accurately reflects the user experience.
Customizable Interface : Version 9 is known for its various themes (skins), including the anime character theme (Shizuku Edition), which is a unique feature of this software.
Lightweight and Portable : It doesn't burden the system and is available in a portable version (no installation required).

How to Read Test Results (Important!)

When you press the "All" button, the software will display a series of numbers that can be confusing. Here's how to read them:

SEQ1M Q8T1 (Sequential): This measures the speed at which large files are transferred sequentially (such as copying a 4K movie or a game ISO file). A high number here is good for content creators or video editors.
RND4K Q1T1 (Random 4K): This is the most important number for general users. It measures how quickly the drive handles small, randomly scattered files.
Note: Windows boot speed, application loading, and computer responsiveness when browsing are heavily dependent on the RND4K score, not the Sequential score.

Why Should You Use It ?

Authenticity Verification: Ensures the SSD you purchased isn't a counterfeit with slow speeds
Problem Diagnosis: If your computer feels slow but the CPU and RAM are fine, dropping benchmark results could indicate your drive is failing.
Comparison: Compare performance before and after tweaking your system.

CrystalDiskMark 9 is a must-have tool for anyone concerned about their computer's health and performance. It's easy to use: simply select the drive, click "All," and let the software run for a few minutes. The results will appear as below:

Here's a health and performance analysis of the CrystalDiskMark 9 results for the Colorfire 1TB NVMe PCIe SSD:

1. Healthy NVMe PCIe Gen 3.0 SSD

The Read score of 3277.90 MB/s is a strong indicator that this drive uses the PCIe Gen 3.0 x4 interface.

Gen 3 Maximum Limit : Approximately 3500 MB/s, while the result for the Colorfire 1TB PCIe NVMe SSD is 3277 MB/s. This means this drive is operating close to the maximum capacity of the Gen 3 slot. This is excellent (high-end) performance for the Gen 3 class.

2. Detailed Analysis of the Numbers

Sequential - Large Files :

Read: 3277 MB/s | Write: 2328 MB/s. Very fast for copying large files, installing games, or rendering video. For comparison, a typical SATA SSD (2.5-inch box model) caps out at 550 MB/s. So this drive is 6x faster than a regular SSD.

Random 4K Q1T1 - Responsiveness :

Read: 53.25 MB/s | Write: 155.94 MB/s. These are the most important numbers for everyday use (booting Windows, opening applications). A score of 53 MB/s for random reads is considered solid. Typically, mid-range NVMe SSDs are in the 40-50 MB/s range. Anything above 50 MB/s ensures a very responsive and snappy computer.
