Thecus N0503 NAS
Jan 7th, 2010 | By AnthonyJBOD, 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.
Starting with our first set of tests, the N0503 managed approximately a 50 MB/s throughput rate.
Next, the Re- Reader test measures the system’s caching ability. It is typical that Re- Reader results are significantly higher than those reported in the Reader test as the test measures reading performance of a file that was previously read. In the case of the N0503 however, we saw minimal differences in transfer rates.
Writing averaged out at 20 MB/s which is fairly good. With the Re- Writer test, cache significantly increases system performance.
With cache accounted for, write throughput jumped up into the range of 50 MB/s. When writing a previously written file, the overhead required to process where data will be stored on a specific storage media is already determined, the system in a sense is required to do less thus accounting for the vast improvement in performance.
