So where do I stand when it comes to evaluating the QNAP TS-219P as an overall unit? The benchmark results are certainly respectable. You can count on performance in the range of 20 to 40MB/s depending on file size and transfer rate. The difference between RAID 0 and RAID 1 is large enough that you'll notice a small increase in speed but at the same time small enough that you won't be waiting forever while data is duplicated to both drives.
