Test Results

Test1: ES-8200 RAID Series

Test2: ES-6600 RAID Series

a)1 Worker

b)5 Worker

c)10 Worker

With standard disks, 3-4 workers is the maximum value. With higher number of workers the result stays the same. With Mtron we still see a significant growth for write random values.

Comparison SSD against standard disks (Seagate 1 TB)

Mtron 7500 offers a up to 20 times higher throughput in read random access. Write random looks similar:

Summary

We tested these SSD successfully in our ES-6600 and ES-8200 RAID Systems (Controller by Areca and Infortrend).
In random access mode, i/o rates were much better then with hard disk drives. Especially with read random access, we achieved up to 20 times higher results.
Other observations:
These disks are very lightweight and of course they are absolutely silent. An overall impressive product.
