Plextor M5M 256GB mSATA 2-Drive SSD RAID Report

By: Jon Coulter | RAID in Storage | Posted: Jun 17, 2014 10:07 pm



Version and / or Patch Used: 2.47


ATTO is a timeless benchmark used to provide manufacturers with data used for marketing storage products.




Read transfers max out at 1.018 GB/s, while write transfers max out at 0.807 GB/s.


Sequential Write




Sequential write transfers ramp up faster than the rest of the arrays on our chart.


Sequential Read




Sequential read transfers ramp up quickly, but finish second to last.



Anvil Storage Utilities


Version and / or Patch Used: RC6


Anvil's Storage Utilities is a storage benchmark designed to measure the storage performance of SSDs. The Standard Storage Benchmark performs a series of tests; you can run a full test or just the read or write test, or you can run a single test, i.e. 4k QD16.




8500 points is good performance. It's even better when you consider these drives are handicapped by a lack of NAND channeling.


Read IOPS through Queue Depth Scale




Read performance is lower than most of the arrays on our chart.


Write IOPS through Queue Scale




A lack of NAND channeling is delivering lower than average write performance. Samsung's mSATA EVO, with its "Turbo Write" technology, writes much faster as long as the amount of data being written fits within the EVO's emulated SLC layer.





Version and / or Patch Used: 3.0 Technical Preview


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


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.




Overall, a very good performance.




4k:QD32 read performance is excellent, surpassing our mSATA EVO array.




Write performance overall is below average; however, our M5M array has excellent 4k:QD4 performance.





Version and / or Patch Used: 1.7.4739.38088


AS SSD determines the performance of Solid-State Drives (SSD). The tool contains four synthetic as well as three practice tests. The synthetic tests are to determine the sequential and random read and write performance of the SSD.






With the last of our synthetic testing completed, let's move to our light usage model testing to give us a better idea of what's under the hood of our M5M array.
