Typically, with modern day software, a record size of 64kb is used with larger files. With the sheer amount of data conveyed throughout the last few tests, it would usually be hard to accurate gauge actual performance, and even harder to do so across different RAID configurations. However, as we have seen so far, the N0503 performs fairly identically in all tests. Still, for tradition’s sake in the next section, we will be comparing the data compiled through the tests we ran earlier to gauge performance over the various RAID configurations.

No surprise, as we have found earlier performance tends to fall between the upper 40 MB/s and 50 MB/s range.

With our next set of graphs, things get a bit more interesting. While it does reaffirm that regardless of RAID level performance remains fairly consistent, we also can see how dramatic the effect of cache is on writing. Especially in the re- writer test. With smaller file sizes the effect of cache is enormous which in daily usage of office productivity type activities or even network installed applications will see significant benefits.

Just to finish up our look at IOZone, we are going to have a look at average values of each test with a record size of 64kb further digesting our data for a definitive indicator of day to day performance and what one can expect out of the unit. With read performance the drive achieves a throughput rate of 50 MB/s and for write performance typically 30MB/s- 35 MB/s.
