DiskBench - Directory Copy
Version and / or Patch Used: 188.8.131.52
Developer Homepage: Nodesoft
Product Homepage: DiskBench
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, insuring an accurate test result.
Write Transfer Rate
The Extreme II's real-world random write performance is outstanding.
Read Transfer Rate
Random read transfers for three drives in RAID 0 are pretty outstanding.
Looking at the chart, we see that a two drive Extreme II array has better write performance than all the other arrays on our chart. Compressed data is choking the Chronos array and the EVO array has run out of its "Turbo Write" emulated SLC layer capacity. When it comes to reading random data, the Chronos array and the EVO array have the advantage.
