Performance: Intel IOMeter DataBase Pattern
A special Database pattern allows to study the peculiarities of HDDs firmware in greater detail. The requests size is 8KB. To evaluate the ability of different firmware versions to combine the reads and writes the reads/writes ratio has been changed from 0 to 100%. The measurements are all taken in operations per second.
All Barracuda drives show very smooth graphs, without any splashes or drops, although they still behave very differently. If Serial ATA drives are pretty loyal to the writes, the ATA modifications are completely indifferent to them. Barracuda SerialATA V manages to combine reads and writes very efficiently, while the new generation of Barracuda 7200.7 drives still needs to catch up with it on that.
