Jan 12, 2021 CrystalDiskInfo is a small benchmarking application for hard drives. The usage of the program is pretty simple and allows you to test the speed of connected hard drives. It uses different sizes blocks to test the performance. CrystalDiskInfo is a pretty accurate program because it measures random read and write speeds using differing block sizes. See full list on crystalmark.info.

I have a Samsung 840 EVO 120G SSD, and my CrystalDiskMark results are the following:
The problem is that I don't know what these categories mean (except Seq Read / Write). So I have 3 questions:
1. What do Seq Q32T1 / 4K Q32T1 / 4K mean?
2. What are the equivalents for these in the SSD's specification or how can I calculate them (if there isn't an exact match)?
3. What values would be normal according to the specs?
Thanks,
hazazs

CrystalDiskInfo is a small benchmarking application for hard drives.
The usage of the program is pretty simple and allows you to test the speed of connected hard drives. It uses different sizes blocks to test the performance.
CrystalDiskInfo is a pretty accurate program because it measures random read and write speeds using differing block sizes.
The user interface of the app is pretty straightforward and provides speeds as graphs combined with some speed statistics.
Overall, CrystalDiskInfo completes its tests without leaving much of a footprint in terms of CPU and memory usage but to get accurate results, it is recommended other applications remain closed.
CrystalDiskMark is software which can benchmark hard drive speed.
Features and highlights
- Measure sequential reads/writes speed
- Measure random 512KB, 4KB, 4KB (Queue Depth=32) reads/writes speed
- Select test data (Random, 0Fill, 1Fill)
- Theme support
