QNAP TS-419P+ Turbo NAS
Feb 3rd, 2011 | By SimonWhile, IOzone allowed us to very thoroughly assess QNAP’s TS-419P+’s performance at the hardware level, we’re going to look at Iometer to compare two measures of throughput: pure sequential and pure random. Reading and writing sequential data is of course much faster than random access due to the physical nature of conventional drives and the time it takes to retrieve data, but to an extent, the drives’ configuration and system hardware also play a role.
We start with the sequential performance where we see a clear peak in the read results at the 64K transfer size. At about 128K in size the performance begins to degrade. Thankfully most applications use the 64K record size so we shouldn’t be too concern about the results beyond that. With sequential write, the performance also plateaus at 64K for each of configurations.
As expected, the random performance is much worse than the sequential. It falls of the map once the transfer size exceeds 1MB.
