TRENDING NOW: 10TB SSDs are on their way thanks to Micron and Intel's new 3D NAND

Plextor M5 Pro 256GB PX-256M5P Solid State Drive Review - Benchmarks - CrystalDiskMark

CrystalDiskMark is a disk benchmark software that allows us to benchmark 4K and 4K queue depths with accuracy.


Key Features:-


* Sequential reads/writes

* Random 4KB/512KB reads/writes

* Text copy

* Change dialog design

* internationalization (i18n)


Note: Crystal Disk Mark 3.0 Technical Preview was used for these tests since it offers the ability to measure native command queuing at 4 and 32.




In CDM we're looking at 4K and native command queuing performance. The QD1 4K read speed of nearly 37MB/s is the fastest out of the Plextor group of drives. When scaling up to QD4, the M5 Pro leaps ahead by 10MB/s over the second fastest Plextor in the same test. When we ramp up to QD32 the M5 Pro walks away from every other SSD in our chart.




This isn't the first time Plextor has broken the QD1 100MB/s mark, the M3 Pro managed to do that as well. These days, 100MB/s in 4K writes is just a starting point, but it is still very impressive. In the QD4 test the M5 Pro separates itself from the four month old M3 Pro and it stays ahead in the QD32 test as well.

CDM uses incompressible data to deliver performance data and in this test we also get to see sequential write speed compared to drives based on SandForce controllers. When writing sequential incompressible data the Plextor M5 Pro is a rocket, but the Vertex 4 still retains its lead.
