Plextor M5M 256GB mSATA 2-Drive SSD RAID Report

Iometer – Disk Response

 

Version and / or Patch Used: 1.1.0

 

We use Iometer to measure disk response times. Disk response times are measured at an industry-accepted standard of 4k QD1 for both write and read. Each test is run twice for 30 seconds consecutively, with a 5 second ramp-up before each test. The drive/array is partitioned and attached as a secondary device for this testing.

 

Write Response

Average Disk Response

Write response times benefit most from RAID 0 because of write caching. There is a slight latency increase in read response times for an array versus a single drive.

 

 

DiskBench ? Directory Copy

 

Version and / or Patch Used: 2.6.2.0

 

We use DiskBench to time a 28.6GB block (9,882 files in 1,247 folders) of mostly incompressible random data as it's transferred from our OS array to our test drive/array. We then read from a 6GB zip file that's part of our 28.6GB data block to determine the test drive/array's read transfer rate. The system is restarted prior to the read test to clear any cached data, ensuring an accurate test result.

 

Write Transfer Rate

Read Transfer Rate

Finally our M5M array redeems itself. Most notable, we can see that the M5M has superior flash in comparison to our EVO array, and as such, it has superior write transfer performance to go along with its vastly superior endurance capabilities.
