Performance in Intel IOMeter
Sequential Read & Write Patterns
IOMeter is sending a stream of read and write requests with a request queue depth of 4. The size of the requested data block is changed each minute, so that we could see the dependence of the drive’s sequential read/write speed on the size of the data block. This test is indicative of the maximum speed the drive can achieve.
The numeric data can be viewed in tables. We will be discussing graphs and diagrams.
The Samsung F3 is brilliant at sequential reading and writing, being much better than its predecessor from the F1 series. The Hitachi 7K1000.C, yet another 7200RPM HDD with 500GB platters, competes with the leader when processing large data blocks but fails to do so with small data blocks. Moreover, this Hitachi is actually the slowest among all, including its predecessor and the 5400RPM models, with small data blocks. The Samsung F2 is somewhat slower than the other power-efficient drives whereas the 5400RPM HDDs from Western Digital are very close to each other.
