QNAP TS-419P+ Turbo NAS
Feb 3rd, 2011 | By SimonTypically, 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 was hard to accurately gauge the QNAP TS-419P+ Turbo NAS, and even harder to do so across different RAID configurations. 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.
The chart above really summarizes the performance of the QNAP TS-419P+. In general, you can expect about 100MB/s write and 60MB/s read with JBOD configuration, 75MB/s write and 85MB/s read with RAID 5 and 55MB/s write and 87MB/s read with RAID 6. There’s not too much of a surprise given the overhead requirements for single and double parity.
It’s not until file sizes of over 1GB where system cache isn’t the dominating factor.
RAID 5 and RAID 6 have very similar performance profiles when completing Read and Re-Read tests. JBOD falls to an average of 40MB/s whereas RAID 5 and 6 stay in low 80MB/s.
