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/arrays 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
Incompressible data slows our LSI SandForce arrays write capabilities significantly in this test.
Read Transfer Rate
Read transfers are a whole different matter. LSI SandForce comes out on top in this test, beating out our EVO array.
Compression technology that's implemented in our Chronos Deluxe array has its advantages and its disadvantages, as you can see.
Faster reads as long as some of the data is compressible, but slower writes when most of the data is incompressible.
