CrystalDiskMark
CrystalDiskMark is a small HDD benchmark utility for your hard drive that enables you to rapidly measure sequential and random read/write speeds.
Here are some key features of “CrystalDiskMark”:
- Sequential reads/writes
- Random 4KB/512KB reads/writes
- Text copy
- Change dialog design
- internationalization (i18n)
Unconditioned
Conditioned
Whilst CrystalDiskMark gives a close resemblance to the details seen from ATTO, there is a notable difference on the conditioned read line. Rather than jumping up and down, the line follows a tighter trend with the performance fluctuating by no more than 4MB/s.
Drive Comparison
For the purpose of drive comparison I use the performance figures from both unconditioned and conditioned tests with 0% data fill.
Looking at the real world performance, the M550 does show to not be the strongest drive on the read front – however if we look at the write performance, the Marvel controller shows to be one of the stronger contenders.
