QNAP TS-259 Pro Turbo NASMar 2nd, 2010 | By Simon
JBOD, at the logical level combines physical disk drives into one larger drive. This comes in handy when dealing with an assortment of drives. Where RAID configuration combines drives at the limit of the smallest disk, JBOD does not.
The caching effects had a huge impact on the write and writer results, not just for JBOD but with the TS-259 Pro in general. The cache effects disappear as the file size increases and as we move towards the 4GB file, we see that the TS-259 Pro hits a peak at 120MB/s with a respectable 88MB/s average.
The read and reader results were not affected by caching and the average read and reader just shy of 60MB/s.
